Installing the connector on the antenna cable. How to connect a television cable to each other: splitter, f-connectors, twist and soldering. Instructions for compression - connect with your own hands

To connect the TV to the cable network or digital television antenna, you need to purchase a special television cable and to wear F-plugs on its ends.

With an illiterate solution to this task, the TV when receiving an analog signal can operate unstable or with interference, and the digital image and sound may disappear due to the signal loss in the cable and the places of its connection.

The high-frequency current of the television signal flows through another law. Everyone knows how underwear is pressed in a centrifuge washing machine: the more turnover, the stronger the centrifugal force acts on the water, and it is better removed from the underwear, the underwear becomes land. In his own body, many in childhood experienced, rushing on the carousels, the action of centrifugal force.

The high-frequency current of the television signal in the antenna cable is also flowing. The higher the frequency, the closer to the surface of the conductor it flows. The skin effect is manifested. If you take, for example, the copper wire with a diameter of 10 mm and the tube of the same diameter made of copper with a wall thickness of 1 mm, then the current with a frequency of 1000 MHz will flow on them with the same losses!

Therefore, in the antenna cables used for military and space equipment, to reduce the losses of the signal (attenuation), often the central core and cable braid are covered with a thin layer of silver and even gold. This is very expensive pleasure, and in everyday life, such cables do not apply.

Due to the small size of the television signal in the antenna cable and its high frequency, determine the presence of it in the cable and, moreover, to carry out measurements at home without specialized expensive devices, it is not possible. Only connecting an antenna cable to the TV will determine the presence and quality of the television signal.

Tv cable marking

The largest distribution on the market received antenna coaxial cables of various manufacturers with a wave resistance of 75 Ohm grades RG 6U, SAT 50, SAT 703B and DG 113, which can be successfully used to receive an analog and digital television signal up to the transmission from the satellite antenna with a frequency to 2, 15 GHz. The brands are given in ascending order of the quality of the antenna cable - to reduce the loss of signal (attenuation) during transmission. Marking (designation) is not necessarily applied on the shell of an antenna cable throughout its length through each meter with a digital tag of a pattern.

This antenna cable marking indicates the following:

Cabletech - manufacturer Cabletech (China).
RG 6U / 48 - Cable brand.
High Quality Coaxial Cable - high quality coaxial cable.
75 OHM - 75 ohm wave resistance.
055m - a label of a pattern, with each meter the label varies to 1.

How to choose an antenna television cable

On the shell of antenna cable, the marking should be mandatory, as shown above. Antenna cable must have a wave resistance of 75 ohms (all the TVs and switching devices are calculated on such resistance - amplifiers, splitters, consoles for receiving digital DVB-T2 channels). The outer diameter of the antenna cable must be at least 6 mm. Central veins and shielding braid from electrical copper. This requirements correspond to the antenna cables of the SAT 703B and DG 113 brands. In the RG 6U cable, the central lived steel coated with a galvanic method of copper, the screen of aluminum foil and braids from copper alloy, this is a budget option.

Describe all the television cables presented in the market is not possible, but the information provided is quite enough to choose the right one.

How to install an antenna plug on the cable

There is no need to invite specialists in order to connect the TV to the antenna cable. This work can perform each home wizard independently using a girlfriend if the instruction presented below will follow.

The voltage of an analog or digital television signal in the antenna cable is millions of volt lolts, so the antenna cable connected to the cable network or another TV is not dangerous for a person. You can safely separate the cable without turning off the second end of the splitter or TV. Not dangerous and when cutting a cable, a random short circuit between the central conductor and the shielding braid.

How to install on an antenna cable F-plug

The plugs are sold three sizes for the antenna cables of different diameters. When buying, pay attention to the F-plug approached for your antenna television cable. This type of plug is suitable for an analog, digital television signal and a signal that runs from the satellite antenna.

You can turn the F-plug to the cable by separating it in two ways, with a breakdown of the shielding braid, on the diagram on the left side, and without wrapping it, on the circuit on the right, in accordance with the cutting circuit below.

Reliable F-plug will be held in case of coasting shielding braid, but if you cannot turn it out, you can use the second way.

For the cutting of a television cable, a non-knife pressing, so as not to damage the shielding braid of an antenna cable, its external shell is cut along several centimeters.

After the shell is cut, it is rejected to the side and cuts off at the start of the cut.

Aluminum foil and copper braid are turned away. The screen in the antenna cables is in three versions: one copper braid, aluminum foil and on top of it copper braid (as in my case), only aluminum foil.

Many do not know that to give mechanical strength foil is covered with the inner side by polyethylene. Clean the plastic is impossible. If you turn the plug on the inner side of the foil of the antenna cable, then the contact will not be, or it will be very bad. So that this does not happen, you need half a turning foil half back, then the conductive side will be outside.

There are situations where the diameter of the hole of the internal thread F of the plug is greater than the diameter of the antenna cable. In this case, you need to put several layers of insulating tape to the antenna cable before breaking the foil to adjust the cable size. Next to do everything as described. Insulation from the central speaker on the technology described in the article "Preparation of wires to installation" is removed.

Foil is screwed down the foker "Cheating to the cable".

The central livelio of the antenna cable is bought so that about 2-3 mm remains to be left.

Hands up to the stop the second half of the plug, and the F-plug is ready for operation.

There are cases when after inserting an antenna plug in the TV socket, the cable has to be bend at right angles or it is impossible to install the TV close to the wall due to the interfering cable. In this case, you can use the F-socket - the plug of the corner structure.

The difference between the two plugs described is only in their form. The installation technology on the television cable plugs of the direct and angular design is the same.

How to install an old design plug on an antenna cable

Before the appearance of antenna F-plugs, the plugs of another design were used, which also did not require soldering, but were connected to the antenna cable in their technology.

Before starting the installation of the plug on the antenna cable, you need to hold it for the metal part, unscrew, rotating counterclockwise, plastic case. Then the housing is to wear on the cable so as not to forget.

The next step is to prepare an antenna cable to install. To do this, the blade of the knife is needed to cut through its outer shell for a length of about a centimeter. Next, remove the shell and cut the shielding braid by 5 mm. Delete five millimeters of insulation of central veins. Now the antenna cable is ready for sealing in the plug.

When refilling cables in the plug you need to exclude the touch of the conductors of the braid fasteners of the central core. Pliers crimped the petals of the antenna plug around the shielding winding. There should be no great effort. The main thing is that there was a reliable contact.

The last step is to turn plastic on the metal part of the plug and insert the plug into the television socket.

Where to insert antenna cable on TV

After the connector is installed on the cable, you can connect it to the TV. The jack for connecting the TV to the antenna or cable network is usually located on its back wall and labeling is applied in the form of an abbreviated inscription "Ant".

In the photo with the right of it, it is seen a nest for connecting an antenna. The socket is special, standard and different from all other connectors and sockets available on the switch panel. Therefore, it is wrong to insert an antenna plug to another nest is physically impossible. Any of the connectors are well inserted into the television socket, the installation of which is considered in the article above.

In modern TVs to receive a television signal, two connectors are installed to connect antenna: - cable (digital) television and satellite antenna.

One, which is denoted by RF (ANT 1 IN), is designed to connect the antenna of a digital television or cable network, such installed on all models of TVs, both old and modern. The second began to install recently, LNB (ANT 2 IN with external thread) is designed to connect the satellite antenna.

If the TV is supported by the DVB-S2 standard, then the satellite antenna can be connected without a receiver directly to the LNB connector. To receive digital television channels from a television tower to an individual antenna, the TV must support the DVB-T2 standard. Therefore, when buying a TV, you need to pay special attention to the list of broadcast standards that it supports.

To receive a TV signal from a given connector, you need to select an antenna signal source or satellite television and perform automatic or manual channel configuration.

How to connect an antenna cable to a TV without a plug

There are situations in life that an antenna cable is urgently to TV, and there is no plug at hand. You can temporarily connect an antenna cable without a plug. To do this, you must first remove the upper sheath for a length of 5 cm, develop and unscrew the shielding braid, remove the insulation from the central cable vein and the core itself beg in the loop. The width of the looping should be slightly more holes in the central socket of the connector.

If the connector on the TV is in the photo, then the central contact needs to wear an insulating tube. Next, the loop is inserted into the central contact, and the shielding braid is refilled into the screwdriver blade connector. The main thing is to avoid contacting the wires of the shielding braid with the central residential cable.

If the braid is aluminum, then you can insert it into the television connector and to fill thin copper wires into free space taken from any multi-core copper wire. So that the wire does not fall out from the TV connector, you can fix it with several toothpicks or matches. Such an improvised connector will serve quite reliably.

How to connect an antenna cable to crab without a plug

The cable preparation occurs in the same way as for putting on the F-plug, the central lived inserted into the crab f-connector, and the screen is put on the protruding part of the crab connector and is fixed by any wire or clamp. As a last resort, you can fix the cable, tightly casting several layers of the tape. It will not work no worse than with the F-connection.

If you use a clamp with a screwing device, the quality and reliability of the connection will not be worse than with the F-connector.

What antenna plug is better

The answer is unequivocal: the best of the three discovered plugs for the television coaxial cable is the F-plug. It is easy to notice in the photographs above, not even owning special knowledge.

As you can see, the antenna plug of the old construction and the Soviet antenna plug has a small portion of the central cable vein, not closed by an embossed braid. This violates the homogeneity of the wave resistance, which leads to minor losses of the television signal.

The F-plug does not have an open portion of the central veins of an antenna cable. Another advantage of an antenna f-plug is simplicity. Having a minimal set of standard tools, without skills, almost anyone can wear an antenna F-plug on the cable.

How to connect multiple televisions
to cable network or antenna

Connect multiple TVs to the cable network or an antenna that transmits an analog or digital television signal is not more complicated than one, except to be put on the cable not one F-plug, but several. To do this, there are splitters of a television signal, referred to as "Crab", they are also called "splitter", "splitter" or "divider".

In the crab there is one connector to connect a signal from an antenna or splitter in the entrance, marked in (input), and several connectors for connecting TVs are marked with OUT (output). If there is no marking, then usually the entrance is in the crab on one side of the case, and the outputs in a row on the opposite. All outputs for the correct operation of the crab must be connected to the TVs.

If you exit two, then to two TVs, if the output is three, then to three, and so on. There should be no free connectors on the crab. If there is no connected output, it must be loaded into the resistor resistance of 75 ohms. Or they say, put the plug. But at the same time, part of the useful signal will be lost, it is better to use a crab that has the number of taps equal to the number of connected TVs.

The design of the splitter is a thin-walled housing from the silumin or brass, in which the connectors for connecting F-plugs are at the same time. The divider diagram is usually transformer, one twist of enameled wire with a diameter of 0.2-0.4 mm, which has been produced through ferrite rings or tubes. Installation of transformers is carried out by attachment. The housing is hermetically closed with a metal lid and is selected or fixed with glue.

For fastening a crab on the wall there are eyeles. In the case there is also a thread with a screw for grounding, although where to take an earthen wire in the overwhelming number of apartments, it is not clear. It is usually not ground, so it is possible on some velocked channels from the wires of electrical wiring, the Internet, telephone passing next to the television cable. If possible, when laying the cable, such a neighborhood should be avoided. For a more detailed acquaintance with the design and electrical circuit of the crab, you can visit the page "As an antenna television amplifier to connect to the power supply".

If there is a desire, then the crab that is not inferior by technical parameters expensive samples of famous firms can be made with their own hands.

When connecting TVs via the crab, the level of the television signal, reaching each TV connected to it, regardless of whether the TV works or not, due to losses in the crab and the additional cable length will decrease. When connecting two TVs - by 30%, three - by 60%, four - 90%, and if an analog or digital television signal coming to the crab is already weak, then the image quality on all connected TVs can significantly decrease. Typically, the signal in cable television is quite powerful, and its level is enough for the normal operation of all connected to the TV crab.

How to connect an antenna cable
to the highway of the television signal at the entrance of the house

Typically, the television cable is paired on the roof of the house and further, after enhancing the main amplifier, branches down at home. Since there are different packets of television programs, then at the entrance to the entrance, the cable is branched with a filter crab, which is a crab with two outputs. From one output, the signal comes out unchanged, and from the second output is a trimmed filter at a high frequency. Thus, it is limited to watch all television channels for those who buy cheaper social packages. Therefore, two cables pass along the entrances down.

If you inspect the walls in your entrance, then you will definitely find a metal box on each floor, from which television antenna cables go to apartments. In modern houses, the boxes are no longer installed, and everyone is placed in wall lockers, in which case you will see a metal door with a lock. In these boxes there are subscriber tv television signal. If you remove the cover from the box or open the door of the locker, then you will see approximately such a picture. In the photo on the left, the coupler for the subscribers of the full package of television programs, and on the right for the subscribers of the social package.

According to the rules, the couplers must be fixed and grounded, but the cables to simplify the work do not. Perhaps this is better, since if the grounding is poor quality, then such a ground can create interference.

The couplers installed in switching boxes are not fundamentally different from crabs to connect multiple televisions, but they work somewhat differently. One F The connector is used to connect a cable that runs from the In (Login). The second OUT (output) is designed to transmit the signal to the next coupler, the installed floor below. The remaining F TAP connectors (removal), they can be from one to five, are designed to connect subscribers, that is, to connect television cables going to the apartment.

Not connected subscriber connectors should not be. In case of disabling one subscriber, allow for non-payment, it is allowed instead of a cable to install a F-connector with a loading resistance of 75 ohms. If you want to connect a new subscriber to a cable television network, then the splitter into two subscribers, as in this example, is replaced by three disconnect.

Thus, to connect the TV to the cable network, a segment of a television cable required length with the antenna F-connectors installed at the ends is. One F-connector of the antenna cable is connected to the subscriber coupler in the entrance, and the second is to the TV.

What is the difference between the crab from the coupler

In the crab, the power of the incoming television signal is usually divided into equal parts between all connected TVs. Unlike the crab, the subscriber in the reseller is allocated only a small part of the signal incoming signal, about 6 dB.

To ensure a sufficient level of the television signal entering the subscribers, the signal to the input of the branch is supplied from the main power amplifier, depending on the number of connected subscribers. In the aggregate, all the couplers installed in one entrance are crab with numerous branches.

Amplifier television signal

If, after installing the crab, the image has become unsatisfactory, then it will have to additionally put a TV amplifier before it. The amplifier is arranged in the same way as the crab, but in its case there are additionally installed more active elements (transistors or chip), enhancing the video signal. For a television amplifier, it will additionally need a power supply voltage, and it is necessary to take into account when choosing a place of installation.

The television amplifier must be installed as close as possible to the television signal source, since the amplifier enhances with a useful television signal and noise. The photo shows the TERRA HA123 television amplifier, designed to work in a home television network with one output, with the ability to adjust the gain from 8 to 28 dB. If possible, the ideal option is to place the amplifier directly in the box of the trunk splitter of the signal in the apartment.

If the TVs are located not far from the television amplifier, it is more expedient to install instead of a television amplifier and a crab only one television signal amplifier with multiple outputs. For example, Televes 5523 television splitter amplifier (Spain) having a gain of 16 dB and five outputs, which makes it possible to connect to 5 televisions to it.

If the signal is taken from an individual antenna, there are amplifiers that are designed to be installed directly on the antenna instead of matching the loop. The antenna amplifiers provide high-quality reception at a distance from the transmitting antenna to 100 km.

An antenna amplifier Depending on the signal level at the antenna installation point, it is required to select the gain by the gain for each specific case. The supply voltage for such amplifiers is supplied by a coaxial cable.

Fighting interference
Installation on the antenna cable of the ferrite ring

Sometimes after connecting to cable television or antenna, several TVs using a crab on some channels may occur in the form of chaotic arising white or black dots, running waves or grid on the screen. When receiving digital television, the image and sound can periodically disappear or completely absent.

This may occur due to the angular signal input of the high-frequency signal of the interference from the heterodyne, parallel to the connected TVs or other sources of interference. Interference is not excluded from televisions connected in neighboring apartments.

The level of such interference can be significantly reduced or even eliminated interference with the help of the installation on the Ferrite Ring cable.

Effectiveness of suppression of interference by a ferrite filter depends on the area of \u200b\u200bthe ring cross section: the area more, the more the inductance of the throttle made. The ferrite ring dressed on the antenna cable forms the throttle and together with the p-shaped high frequency filter forms a high-frequency. Maximum interference suppression will be achieved when you install two rings on an antenna cable at its ends.

Ferrite rings are sold in stores and there are two types: solid and consisting of two halves pressed into the plastic case with latches. But you can do without unnecessary costs. If you look at the interface wires that run from the computer's system unit to the printer, scanner, monitor and other peripheral equipment, you can see the thickening of cylindrical cables. These are ferrite filters.

Surely you have a dust old kinescopic monitor or there are unnecessary interface cables. It is enough to cut the plastic with a knife, remove the ferrite ring and install it on the antenna cable. After installing a frit ring, the interference on the TV screen will no longer interfere with viewing television programs.

In order for the TV to show, it must be connected to the antenna. To do this, the TV connector is provided on the TV, the so-called, antenna socket. Another part of the connection, the plug, mounted on an antenna cable, which is actually connected either with an antenna, even satellite, or with a cable television network distribution box if the owner is connected to it.

In contact with

Plug for television

Previously, in order to connect the plug to the cable, it had to be soldered. Then began to use antenna connectors that are mounted baseing bases. In the first models of this detail Central hastered antenna wire I was screwed to the contact with the screw. And finally, now use the plug of the international standard type F. Actually, this connector is just a sleeve, which consists of two parts and winds on the antenna wire.

To make a high-quality picture on TV, and the signal was not lost, it is necessary to make a good contact in the junction site. With incorrect solutions, this seemingly simple task, the TV will work with interference both in the image and in sound.

To correctly make the connection of the antenna wire with TV, it is not necessary to call a specialist. All manipulations It is possible to make it yourself with the help of simple tools that everyone has.

To solve this problem, it will be necessary:

antenna cable (in a different coaxial).
f. type plug
knife or stationery cutter.

What is cable?

Antenna cable is a multilayer wire, which, due to its shielding abilities, can transmit a stable signal. Consists of central veins, copper wire, dense plastic isolation, aluminum foil (second conductive element), shielding a nick, which extinguishes interference and final external insulation, and protects against weather and mechanical effects.

The market now presents a wide variety of these products as domestic production and imported.

How to prepare cable

Having everything you need, you can proceed to connect the antenna to the TV. Attach the plug to the antenna cable Satellite or other antenna, possibly in two ways: wrapping the shielding fever and without wrapping it. Better and reliable for contact will be wrapped with a shielding fever, but if it is not possible you can not wrap.

In order to separate the cable, take a knife or cutter and, retreating 1-1.5 centimeters from the end of the cable, neatly cut the external insulation in a circle.

The main thing is not to damage the fever and aluminum foil. Remove cut insulation. Now the open part of the patch and foil must be wrapped back to the wire itself. There is one nuance here. So that the foil was strongerHer on the inside is covered with polyethylene. Clean the layer of plastic without damaging the foil unreal. If you just put the plug on the head of the foil contact will be unimportant or, in general, bad.

In order to avoid this, it is necessary to half the foil back and the conductive part will be on top. Then we exempt from insulation the central core, retreating 0.5-1 centimeters. Again, we try not to damage the wire itself. Now we retard the first half of the plug on the foil. Watch that the central wire falls into the core of the plug. After, flooring "biled" Part of the central core, so that it performs 4-6 millimeters from the cape nut. In conclusion, the second part of the plug is screwed to the stop. And our plug for connecting antenna is ready for operation. You can use for satellite antennas, and for analog TV.

If the foil is not fascinated, the upper insulation is simply cut off, the patch is removed and the plug is screwed to the open section of the cable.

If the prior modification plug was in the hands, which also did not require soldering. It is necessary to connect it to the TV cable as follows. Plug Disassemble, disconnecting the plastic half. To put this plastic part on the wire in the first place.

How to connect a TV to antenna cable

To connect the TV to cable television, a cable is required. At its end, I need to build a plug specially intended for the television antenna. If User. not very well versed In this question, it is better to seek help from specialists. Because if it is incorrect to do this work, the analog, and digital signals will not work correctly, which is why the image quality is lost on TV.

Cable selection is of great importance. Even the TV is the last brand and correctly put on the ends of the cable F plugs can not give excellent image if a low-quality cable will be used. And what is the best cable, and how can I learn from many offered on the market?

To do this, it is necessary to have a representation how high frequency of the television flow flows through the cable. And the higher this current indicator, the closer it passes to the surface Explorer. Due to the small height of the television signal in the antenna cable and its high frequencies, it is impossible to determine without special devices. Determine there is a signal or not, you can connect the antenna to the TV.

The most purchased and widely known on the market are Cables with a wave resistance of 75 ohms, which are greatly used for receiving and transmitting television signals. Marking produced depending on ascending Quality. It, as a rule, is applied to the top layer of an antenna cable throughout its length, through each time meter next to the digital mark of the pattern.

If the consumer owns the skills of working with wire and certain knowledge, then it may well conduct an independent connection of the TV to the antenna. The main thing is to follow the instructions and not retreat from the rules.

It is important to remember that the voltage of the television signal in the antenna wire is the magnificent shares of the volt. Therefore, such a cable is not dangerous for human life.

Happens after the antenna plug in the nest of the TV is inserted, move it closer to the wall becomes impossible, because cable interferes. In order to get rid of this problem, you should use a special F -Gnex, that is, the plug of the corner design.

These two plugs, in fact, the same, and the installation of them is made equally. The difference is only in shape.

But before their appearance, other plugs were used, the connection technology was completely different.

Is it possible to do without a plug

There are times when you need to urgently connect the cable to the TV, and there is no soldering iron. It turns out, you can do without his help. This will require just remove the top layer Shell and remove the overall. Then remove the insulating layer from the central wire cable vein. The wire itself must be collapsed into the loop, the width of which is slightly more holes in the jack of the television connector.

What antenna plug is preferable?

Definitely - the best plug for the television cable is the plug. His advantages is Implementation of the excellent quality of the television signal, as well as simplicity of installation. That, undoubtedly, more like homemade masters.

Objective reasons in order to somewhat lengthen or increase the already laid television cable, stretched into a particular room, can be how much. Most often, the need for this occurs when transferring a household television receiver from place to place (or its movement from one residential premises to another). One way to which extension is carried out, assumes the presence of a set of two connecting elements shown below.

Note! Such an elongation is also beneficial because the use of a new one-piece segment of cable is not quite justified from an economic point of view.

At the same time, in the case of its extension, in which the connection of the television cable is organized (more precisely its individual fragments), additional costs for special adapters can be minimized.

Television cable device

Before connecting the television cable in the place of the intended insertion of the extended area, you must familiarize yourself with the structure of the wire used to transfer the television signal.

Additional Information. The name of the coaxial cable is chosen so because it uses a special structure (coaxial), whose character is well distinguishable in the figure below.

The composition of typical television cables of the antenna type includes the following mandatory elements:

Central veins placed in solid polypropylene isolation;
Screen made of aluminum foil protecting the central wire from electromagnetic filing;
The outer patch, intended for additional protection against external fields and forming the outer part of the coaxial structure;
Polyethylene insulation, protecting telecalers from mechanical exposure and unforeseen destruction.

Taking into account this composition before lengthens the television cable, it is necessary to carefully prepare each of the connected parts. Specialists call this operation by the "cutting" wire, in the process of which individual sections in the pieces of dusting are cleaned of isolation and are molded to the future joint.

Types of docking connections

The high-quality connection of the antenna cable (as well as its individual parts), carried out with the purpose of elongation, is possibly the following known methods:

Take advantage of the corporate extension, entering free sale in the form of a segment of a coaxial cable with a length of 2.5 to fifteen meters;
Purchase in the store of radiostics special F nests and arrange with their help a classic discerning connection;
Use for these purposes adapter-connector type "splitter";
Make an extension of a separate piece of wire connected to the main line by means of a regular twist, and to increase its reliability to use the soldering method.

The first of these options belongs to the most reliable and repeatedly proven ways to eliminate the antenna wire, however, at the same time, it is the most expensive. The second and third approaches to the problem of extension of the cable at a cost preferably than the first, but in this case it will take a trip to the store for additional spare parts.

The easiest way to articate pre-prepared (stripped) cable segments is the method of formation of twists at the points of the connection and their subsequent soldering. However, in this case, the reliability of the resulting compound leaves much to be desired, since the central wire in the twist can easily break.

Important! Regardless of the selected method, the products of the same brand and thickness should be used to obtain reliable articulation as the extensionable TV cable.

It should also be remembered that, in accordance with the standards applicable in Russia and GOST "Cables. Television ", the gasket of communications is carried out by a type wire of the RK 75 brand with a wave resistance of 75 ohms (figure below).

Among the foreign samples of the same products, such well-known cords like RG6 and RG59 are the most common.

Helicing education with adapters

Consider the subtleties of increasing the wires when the extension adapter is used for these purposes (ready-made or made on the basis of special connectors). An option is ready for the use of extension cable for a television cable, despite its relative high cost, it seems most convenient in terms of labor costs.

To independently make such a joint, the user should issue a contact connector at the extended end of the wire already laid in the apartment, suitable for the retaliatory part on the purchase of the product. It is made from the calculation that the adapter acquired in the store at both ends has connections made in the form of a conventional antenna plug.

Another way to connect an antenna for a TV through a lengthetic cable segment is assumed to be used for these purposes of special F-type sockets.

Additional Information. To obtain elongation, two sets of such connectors will be required.

Before lengthened the television cable by insertion, all connected parts should be prepared for the upcoming operation. For this you need:

Remove the protective insulation on each of the 4 docking ends on a small area (about 2-3 cm);
Bend the protective fever along with the on-screen foil towards the insulation (see photo);

Next, the central core should be shortened so much so that from no more than 5 millimeters from the direct part of the connector from the straight part of the connector (for this you first need to try it at the place of installation);
Upon completion of all preparatory operations at one of the ends of the insertion, the plug is shutdown, and on the other - nest;
At the ends of the stripped (old) wire, the same method is formed by the response parts of the F-connector.

Another known version of the cable extension is to apply the Splitter type tees that are embedded in the torn chain and allow you to create a lengtheal removal. The procedure for the formation of this connection is practically no different from the method discussed earlier, which involves the use of the F. type connector

A feature of such a compound is the ability to obtain an adapter for an internal household network, which allows you to organize a TV signal of a television signal throughout the apartment. At the same time, the latter will be transmitted to all television receivers almost without loss of quality.

Compound by scruit

The easiest, but not very reliable way, using which you can equip an extension fragment of an antenna cable, is the connection of the elements by a twist. The disadvantage of this approach is the high probability of the breakpoint of the central core even with a minor deformation or bending of the connection site.

In addition, when carrying out this operation, it is impossible to do without a soldering iron, through which the twisted contacts are first thoroughly poured, and then soldered.

Note! Before connecting the antenna cables with each other in this way, you must choose products in soft isolation.

Before connecting a new cable area, for example, it is also desirable to trace so that the protective shell is not only durable and elastic, but also could withstand multiple bends. In addition, it is important to prepare twisted parts in advance, to solder that will be noticeably easier, if you first clean them from the lacquer isolation, and then carefully climb.

Forming of the conclusions in this case is somewhat different from their preparation under the previously disconnected connection (adapter). For this you need:

Remove the insulation at a distance of about 3-4 centimeters from the extended end of the cable product (see the drawing below);

The same will need to be done with the second harvesting of the cable used as an extension cord;
Then it is necessary to split the copper fever of each of the collected parts, after which it will be possible to access the polypropylene insulation of the central core;
Following this, it is necessary to carefully cover the protective shell of polypropylene, growing not to touch the edge of the knife below it;

Important! In case of non-compliance with this requirement, the likelihood of the maintenance of the central core in this place during operation of the connected cable is significantly increased.

Upon completion of the preparatory operations, it is necessary to clean the cable copper veins with the help of small skins, and then fill them using rosin and solder;
After the formation of a twist consisting of two central lives, in order to reduce the loss of energy at the junction site, it is carefully disappeared by the soldering iron;
The resulting twist is insulated with a non-conductive material of the material (ordinary insulating tape, for example), and a twist is generated from the ends of adjacent feet over it;
At the final stage of work, the resulting compound is closed with an insulating ribbon that protects the place of the joint from damage and deformations.

The same must be done when it comes to connect the second end of the cable insert.

Examples of cable elongation

The main admission of cable lengthening allows you to successfully cope with many problems, including a solution to the question of how to fix the antenna, for example, or to build up to the required length of the cord (photo below).

If, after disassembling a home antenna, it is found that a piece of cable at the connection site to the internal circuit is damaged, it must first cut off and shorten it.

Additional Information. After such a shortening, the length of which should not exceed one centimeter, the docking zone must be prepared for subsequent soldering (as described above).

Before repaired any television receiver, having a cable liner, should also have an idea of \u200b\u200bhow to properly increasing the damaged wire.

In the final part of the review, we note that the user-friendly specialists will repaired the failed cable line faster and better. But in this situation, it should be processed from considerations of savings and the opportunity to independently master not very complex technique for restoring a damaged cable wire or its elongation.

We clean the television cable, without having a subwoofer using a stationery knife. To cut through the protective shell blade should be sharp.

We retreat from the edge of the wire of about 1.5 cm and smooth circular motion, slightly pressed, make an incision of external insulation. Making an incision, the main thing is not to overdo it and do not cut down a thin aluminum braid with vile, which is insulated. We are tightened by cutting shell.
We refuse and reject the screen to the side opposite from the edge of the cable TV.

We take into the hands of the knife and again receding 1.5 cm from the edge with circular motions cut off the inner isolation. It is usually solid white polyethylene. Its thickness will be slightly thicker than external insulation. For ease of removal, you can still make several slots along the entire length (1.5 cm). After removing the inner insulation, the central conductor will seem. It is on it that will be transmitted a television video signal.

We did everything right, and our antenna cable is cleaned of isolation!

That's not all! After stripping a television cable, it is necessary to clip it with the F connector.

How to crimp an antenna (television) cable using F connector (connector).

After stripping, we immediately go to it. Crimping is called the winding of the connector and its fixation.

F Connectors can be slightly different: there are disposable F connectors for crimping, which are not subject to removal after the attachment. There are those that boil immediately over the protective shell.

You screw down the connector in such a way that the central conductor lives can be 2 mm from the edge of the connector, while the central conductor must be strictly in the center and not touch the nut.

Switching socket F per plug TV - To connect the television antenna, satellite or cable television.
Connector BNC plug on F (socket) - To connect AHD / TVI / analog video surveillance.
F connector You should choose from the type of coaxial cable. The most common distribution was the connectors of popular types of television cables: connector f on Rg 59, F on RG 59 Micro, F to RG 6, F on RG 58.

As can be seen, there is nothing complicated in sweeping and burning. If it did not work out the first time - try to make an indent of the antenna cable again.

With proper cleaning and burning wire, we will receive a high-quality connection of the connectors and can enjoy the quality of the pictures from the TV, satellite TV or video surveillance camera.

How to combine the antenna cable.

It happens that when laying you lacked a little length or simply requires it to lengthen it.

Due to the constructive features of the antenna cable, the twist is very difficult to do. The central lived rigid and easily breaks, and the screen is multi-way, which is also uncomfortable when connected.

The problem of scrubs is that such a connection is unreliable. It is worth moving the wire, and the image will be rich. On a television cable, a high-frequency signal is transmitted, which is not enough electrical contact between two pieces.

To connect the television cable, you will need a connecting adapter: F (socket) - F (socket). Adapter is called barrel.

In the barrel, after following the crimping, you connect two antenna cables that you want to combat.

When connecting the plug to the antenna or cable connection, you must follow some rules. This article is about how to connect the antenna cable to the plug without errors. F-connector "Dad"

Connect errors

Perhaps, perhaps with the fact that I will give the most common misses when connecting the cable. When installing the plug, you must immediately pay attention to this to eliminate the troubleshooting in the subsequent.

The inner side of the foil does not conduct an electric current, this is the basis for which aluminum is sprayed. When you break it on top of the braid contact with the F-connector will not be. Therefore, it is better to remove it or expand the opposite side.
When breaking the braid should be paid to all the braid veins to be removed and could not touch the central veins, as this leads to a short circuit. In this case, if there is no protection against short circuit in the cable in the console, this can lead to its failure.
When comprising some types of plugs should not be done too much as it can also lead to a short circuit between the central residential and the screen (braid).

Connect antenna to TV

To properly connect the antenna to the TV, it is better to use a special plug. Currently, the so-called F-connectors (or F connectors) have been widely distributed. They are installed directly on the coaxial cable with a diameter of 6.8 mm with a wave resistance of 75 ohms intended for television equipment.

With this type of connector, additional nozzles can be applied: plug - "dad", "Mom", corner plug, cable connectors. A variety of such antenna adapters for the TV is very large. The advantage of this connection is obvious, it makes it possible to connect the cable without soldering using one knife in a few minutes anywhere. This ensures the reliability of the compound to mechanical effects.

Rusty contacts Cable Connections

Unfortunately, there is enough counterfeit on the market and you can purchase these instances. This means that the connector fell into a wet environment and just rusted. Most likely the insides of such a connector are made of iron, and not from bronze or brass. In this case, it will be observed, its insufficient level or its loss.

You can connect the antenna to the TV without a plug of course, it is enough to establish a contact of the RF connector of the TV and a male. The braid is connected to the housing of the connector and the central live should be included in the central part. Of course, such a connection is not reliable and better to do it, but there is a chance to spoil RF contact TV.

Connect the cable to the plug

F - Dad connector

To immediately connect the antenna cable to the plug correctly, it is enough to observe some sizes and a sequence of actions, while do not be afraid that you can be powder, since the voltage in the cable is very small. So in order to correctly clean the TV cable you need:

at a distance of 12 - 15 mm, make an incision of the outer shell so as not to damage the braid and tilting to the sides away and make it (you can do it and convenient for you);
wrap your braid;
when the foil breaks, take into account that its inner layer does not conduct a current, so it is again turned it around the axis the outer layer up or remove it at all;
cancel the central vein dielectric at a distance of 8 -10 mm from the end and remove it;
screw F - connector on the cable;
tighten the plug into the connector.

If the central spent looks out of more than 4 mm, it may touch inside the connector and do not twist to the end of the nut, so delete too much.

With a small diameter of the cable, you can wind a little tape and already wrapping the braid.

Plug with crimping

In this case, the central lived is clamped by a screw, and the braid is crimped with the plug housing:

the cable is put on a protective cover;
the outer sheath is cleaned by 10 mm;
aluminum foil is removed;
3 mm isolation of the central core;
the braid is screwed to the remaining dielectric;
the central lived inserted into the groove and clamping the screw;
the plug housing is crimped braid;
the protective cover is screwed into the housing.

Connecting the separator of the power supply of the antenna

In this case, when the cable is connected to the power supply, the dimensions change slightly:

Correct power supply to the antenna correctly

the outer protective sheath is cleaned by 15 mm;
removed foil;
the braid shifts to the protective shell;
5 mm is removed by the central vein dielectric;
the cable fastening screws are weakened in the separator;
cable is inserted into the resulting openings and clamping screws.

Be careful when the braid clamp: first, it should touch the lifted platform on the board; Secondly, watch the braid not touched the central veins.
