Connecting the plug to the TV cable. How to connect a television (antenna) cable. Or install F - connector do it yourself

Want to get rid of the cable, but at the same time you like to watch local TV channels? Broadcast stations transmit their programs in the MW and UHF bands in both the old analog form and the new one - in the form of a digital and HDTV signal. To catch this signal, you will need an antenna. We will show you how to connect it. Read!

Steps

Antenna selection

Antenna connection

Determine how to connect the antenna to your TV. This will probably be the so-called F connector or round with thread and a small hole at the end. There are older connector types, such as a Belling Lee connector or flat connectors, but for digital signal It is best to use the F connector.

Please note: If you have an old type connector, go to the radio parts store or the store selling TVs and buy the appropriate adapter. Digital televisions have a dedicated input for receiving a digital signal, usually labeled "DTV" or "DTT." They will not be able to directly connect older types of connectors.

Connect the antenna to your TV using a coaxial RF cable (also known as an “F” cable). There are two main types: with screw and conventional plug. Both options are good, but the screw connection is still more reliable.
Tune your TV. Using the settings menu of your TV (for specific actions, read the operating instructions), set the signal reception to "From antenna" or "By air."
- Some TVs have multiple inputs: make sure you use the correct input during setup. if you have cable TV and several inputs, you can use one of them for the cable and the other for the antenna.
Adjust the antenna. Scan all TV channels to see which channels are in range. If you see a fuzzy picture, turn the antenna so that the signal becomes clear.
- Please note: some antennas are electrically driven, which saves you from having to climb onto the roof to adjust the antenna.
- AT digital televisions There may be special menu options for full scan and manual scan. To optimize the position of the antenna, you should perform a full scan each time you change its position. Every time, write down all the settings, do a full scan and count the number of channels found.
Identify all broadcast sources. Find the source of each channel (distance and angle) with the appropriate map of your area. If all channels are transmitted from one direction (within 20 degrees), then it is better to use a directional antenna.
- If you need different settings for receiving different signals, then write down not only the number of channels received after the scan, but which channels as well.
- Identify the basic parameters you need and write them down.
- To add all channels to your TV menu, do a manual scan after each setting and direct the antenna accordingly for each channel you are watching.
- Some TVs remember channels that are received well enough for a clear picture. You can use this when looking for broadcast sources.

You can buy a better antenna, which is installed on the street. You can also purchase a controlled motor that will rotate the antenna to the optimum position for receiving each channel.
If you need to run a cable, make sure you use a double-shielded coaxial cable with two layers of foil and two layers of braid around the dielectric (these are parts of the cable). This will give you the signal of better quality and reduce the interference - which means a good received picture!
Cable companies also use RF cable to transmit their channels. You can buy a simple switch to simultaneously connect cable TV and antenna to one input.
In the US, on the FCC website, you can find signal reception maps for most US cities as well as a range of signals.
The VCR also has a RF connector on the back, usually even two. If you want to have a VCR connected, connect the RF antenna to the connector entrance video recorder to transmit the signal directly to the video recorder.
- The VCR also has a built-in tuner for channel selection and a mini-transmitter, called a modulator. It outputs a low-power radio signal to the output of the video recorder.
- You can configure this modulator to transmit various channels. The signal will go through the RF cable connected to the connector. Output and enter the tuner on your tv.
- Tune in to the channel you chose to transmit in the modulator. Leave your TV tuned to this channel and use the VCR control panel to select channels.
A better place to buy an antenna is a place for electrical equipment wholesalers. There you can buy the same antennas that the installers use. In addition, you can learn more about antenna pointing methods.

Warnings

Keep in mind that in most countries analog transmitters are disabled in favor of using a digital signal. So you have to buy digital tuner to receive a television signal using an antenna.
Beware of any shaped antennas. satellite dishabout which they say she accepts hundreds channels without having to pay for cable TV and uses "RF technology". This is just a fraudulent way to describe any antenna. You can only receive broadcast channels within range.

Connecting the TV cable is from the staircase to the apartment, with further wiring to the TV. For proper installation of a television cable, it is necessary to follow certain rules, features and specifics of this type of work.

Features cable TV

The cable is recommended to be placed away from electrical wiring.
Television cable is usually placed in the cable channel together with a telephone wire, Internet cable, etc.
The cable in the apartment, it is desirable to stretch the whole parts, without connections.
It is not recommended to allow the intersection of the TV cable with the power networks. If there is no other way out, the intersection should be at a right angle.
For distributing the TV cable, it is advisable to use industrial-grade signal splitters to ensure high-quality contact and signal shielding. Cable twists are not allowed.
Cable lines may be laid only with a specially designed cable.
Do not connect the cable in the bay, or with sharp bends, as this leads to a deterioration in the quality of the image in the TV.
The first section of the cable from the staircase to the home splitter should be placed in a wider cable channel, since in the future it may be necessary to extend the telephone line or signaling.
If the connection of the TV cable in the junction box is supposed to be performed by soldering, then the length of unshielded cable sections should be the shortest, since this significantly affects the signal quality.
TV cable splitters are recommended to be placed in accessible places or in switchboards, for easy access during maintenance.
When laying the TV cable together with the electric cable, it is necessary to use a cable with a central core with a diameter of at least 1 mm, with a double shield.

TV cable connection

Cable selection

A high-quality TV and cable plugs will not provide normal picture quality if the wrong cable is used. The current high frequency TV signal flows differently than the current in the home network. The higher the frequency of the current, the closer to the outer surface of the conductive core it flows. In the antenna cables used for space and military equipment, the cores are coated with a layer of silver or gold to reduce the loss of the television signal.

Marking

Coaxial cables with 75 Ohm impedance of various brands received the greatest popularity. The most used brand has become a Chinese-made RG 6U cable. The designation of the cable is depicted on its sheath along the entire length with digital marks every meter of length.

Marking stands for:

CABLETECH is a manufacturer company.
RG 6U / 48 - brand.
HIGH QUALITY COAXIAL CABLE - high quality coaxial cable.
75 OHM - 75 Ohm resistance.
055M - cable length mark.

Selection

The cable sheath must be labeled. Cable resistance should be 75 Ohms, since all TVs are designed for it. The outer diameter of the cable must not be less than 6 mm. The shield braid and central core should be copper. In the Chinese cable RG 6U, the screen is made of aluminum foil, the braid is of copper alloy, and the central core is steel with copper electroplated coating. This is done to reduce the cost of products.

Installing the plug on the cable

The installation of the plug on the cable can be done independently. The voltage of the television signal in the cable is very small, so it is not dangerous for humans. The connected cable can be cut without fear of electric shock. The closure between the sheath and the central core is also not dangerous.

Different plugs are available for various cable sizes. Therefore, when buying should look at the diameter of the plug. The most common brand is the F-plug.

The cable is cut by 2 methods:

With inversion braid.
Without inversion braid.

A more reliable option is considered with twisting the braid, if you do not screw the plug on the wrapped braid, then use the second method.

To cut the cable with a knife, it is necessary to cut the outer sheath along the cable without damaging the screen.

After the cut, the insulation is folded to the side and cut off.

Copper braid and foil wrapped. In television cables there are three types of shielding:

Copper braid.
Aluminum foil with copper braid.
Aluminium foil.

To harden the aluminum foil it is covered with a plastic film on the inside. Cleaning this polyethylene coating without damaging the foil will fail. Therefore, in order to have a good contact of the wound plug with the foil, it is necessary to partially wrap the folded part of the foil back, then the uninsulated side of the foil will be facing out.

In the case of a small cable diameter, it is wrapped with tape to increase the diameter.

The insulation from the central core is removed in the usual way, like from electrical wires, without damaging the core itself.

Now the F-plug can be screwed onto the foil.

The central core should be bitten off, leaving a protruding part of 3 mm.

The other half of the plug is screwed all the way down, after which the plug can be used for work.

In cases where it is necessary to bend the cable at a right angle, use a special F-socket. This is a kind of angled plug.

These plugs considered differ only in shape. The installation on the cable of the angled plug is exactly the same.

Installing the plug of the old sample

Until now, there are still plugs of the old design that do not require soldering when connected to the cable.

Before installing on the cable, you must unscrew the plastic part and put it on the cable. Next, the cable is ready for installation. Knife need to cut the cable sheath to a length of 1 cm, and remove it. Then the sheath must be cut at a length of 0.5 cm and remove the insulation of the core. After that, the cable is considered prepared for the installation of the plug.

When installing the plug on the cable, it is not allowed to touch the sheath with the core. Petals need to compress on the sheath, without making great efforts, and ensuring good contact. The fixing screw of the core is tightened to the end, without excessive efforts, in order to avoid breaking the thread.

The last step is to wrap the plastic case. After this, the plug is ready for operation.

Solder plug installation

Soldered plugs are still found on older televisions. When replacing the cable you have to re-solder them.

Places for soldering need to be stripped to shine. Then you need to prepare and cut the cable for soldering. Next, the plastic part is put on the cable. Cutting the cable is made by analogy with the previous versions. The shield braid is unwound and divided into two parts. The protruding part of the central core is left 2 mm long.

Before inserting the cable into the plug, the central core is made shorter, to facilitate refueling of the parts of the forked braid. Contact petals are bent to the sides. Shielding conductors are inserted through the holes in the petals until it stops. The core is passed through the middle contact of the plug. Contact petals pressed to the cable.

It now remains to put on the plastic part of the plug until it clicks.

Connect TV cable to TV

After installing the plug cable can be connected to the TV. Cable slot is located on the back of the TV with the designation "ANT". Connect the TV cable to the TV by inserting the plug into the antenna jack.

Connect multiple TVs

Multiple TVs can be connected to one antenna at a time. For this task, use special TV signal splitters, called "crabs", "splitters" or "dividers".

The splitter has a connector for the signal from the antenna at the entrance, and several sockets for TVs. For normal operation of such a splitter there should be no free connectors.

The splitter device consists of a metal case with connectors for plugs. The housing is located dividing the circuit on the basis of the transformer, made in the form of a ferrite ring with one turn of the wire. The case is sealed with a lid. There are lugs on the wall for fixing it. On the case there is a screw for connecting the ground. Usually the splitter is not grounded, since there is no ground wire nearby.

TV outlets

When performing repairs in the apartment it is planned to design the premises. An important issue is not only the placement of interior and furniture, but also the optimal wiring of electrical wiring, the installation of sockets, both electrical and television.

TV sockets can be divided into three groups according to their use and purpose:

Solitary TV sockets have a simple device, so they are widely distributed. They are used to connect to the antenna of a single TV.
Passable TV outlets are used to install them in the middle of the cable length. The device of such sockets provides for the connection of a TV cable from two sides. On the one hand, the incoming cable from the previous device is inserted, and on the other hand, the outgoing cable that goes to the next outlet is inserted.
TerminalTV sockets are installed at the end of a series of sockets.

TV outlet device

The main elements of a television outlet device are:

Case that serves to connect the TV cable. In a single socket, the case does not include electronic filling, and provides only reliable contact with the plug.
The front panel has a protective and decorative function. She is selected according to the room's interior.

The caliper is designed to fix all the elements of the device among themselves, as well as for mounting sockets in the junction box.

I have several popular articles that relate directly to the new DVB-T2 television standard. This, read very useful. And also a review. Just combine the antenna made, and the console and we get digital television. But many people ask me a question - how to connect a TV cable? What is needed for this? After all, you just can’t plug a piece of cable into the console's socket, this is true - you need to properly compress it, and also connect the F - connector on the end. For those who are experiencing difficulties in this my article today ...

Many can now say - for whom this article, because everything is elementary? Guys - yes it is. However, they write to me not only experienced electricians or people - who use the equipment for “YOU”, but also single housewives who find it difficult to connect this cable, or rather, they don’t have any idea about it. Therefore, I ask you - treat with understanding. There will be both photo material and a detailed video at the end, so we’re looking.

What do we need?

Initially, to make digital television, we need:

Antenna cable
F - connector for connection.
Also sometimes a dad-mum connector is needed for installation in the console itself.

Nothing more is needed; from the tools we need only a penknife, or any other, but preferably sharp.

Antenna cable

Before crimping it, we need to select it. For antennas use the so-called coaxial wires, which provide a stable signal, thanks to its screen. If you decompose this cable into components, it consists of:

Central copper wire, the first conductor, the most important
Tight insulation.
Aluminum foil is the second conductor.
Aluminum braid - "screen", prevents electromagnetic interference, its use improves television signal.
The final plastic insulation protects the entire structure from mechanical and weather damage.

I just want to answer the question - is it possible to use ordinary copper or aluminum wire? In theory, of course it is possible, but it is not protected from interference, that is, it does not have a “screen”, and the quality of the television signal will fall, and significantly! Therefore, we are not wise, but we buy special antenna cable.

Now there is a wide choice on the Russian market - there are both foreign and domestic options (labeled according to European and Russian standards).

If we take Russia (and our standards), then these are options of the form: - PK - 75 - x - x. If you delve a little bit into the technical characteristics, then the figure 75 means the characteristic impedance for our coaxial cable.

If we take foreign options (or Russia, but according to EURO standards), now they are: - RG "X". Usually go - RG 59, RG 6, RG 11 and so on. All of them differ in both resistance and maximum signal transmission length, for example, the RG11 is used in industrial facilities, it can transmit a television signal over a distance of 600 meters, with virtually no loss of quality. But it is expensive and for a simple apartment, where there are no such lengths, it is inexpedient to use it!

To sum up - now the RG6 coaxial cable is widely used, I personally advise it to you, come to the store and point the seller to it in 90% of cases it will be available.

With antenna wiring sorted out, go to the connectors.

F-connector and dad-mom (antenna plug)

The second step - buy the necessary connectors. One of the most important in the connection is the so-called F-connector. In fact, this is just a sleeve that is screwed onto the cable, so you need to take it with the thread inside, this is important! See the photo.

If you have receivers or antenna inputs under the F - connector, then you may no longer need anything, just plug in, twist and enjoy. But in the usual digital set-top box Or do not install this design in the TV! Therefore, we need another “adapter” or antenna plug.

Many will now ask me a question - why not immediately buy a plug that goes to the antenna? It is possible and so, but I did not come across normal, for some reason they constantly break, or the central cable crashes, or the winding screen does not sit well. Therefore, I always buy an F - connector and already an adapter for it, it is not much more expensive, but you can connect the receiver via the F output and through the antenna cable if necessary, that is, you get a universal adapter. And most importantly, he sits at times safer and better! I advise everyone.

In general, it looks like this.

On the one hand there is an outlet for connecting to a set-top box or a TV. On the other hand, the threaded connection with the F output, as well as the hole for the central copper wire.

Now we are fully prepared, proceed to crimp - connect.

Compression instructions - do-it-yourself connection

So, the process is not complicated, but you need to do everything carefully, otherwise just ruin the antenna cable, I will list the points:

We take a knife, retreat from the end of the cable about 1 - 1.5 cm, and carefully cut only the upper plastic winding in a circle - it is important not to damage the “screen” and the aluminum part under it! Remove it!

Now we have aluminum winding and screen, we need to bend them to the cable itself.

Next we have an insulator, retreat 0.7 - 1 cm and cut it to the main core, the main thing is not to damage it either. It is certainly thick and durable - but without fanaticism! Remove the insulator.

Take the F - connector, and just twist it on the curved insulator, it is important that the central wire fell into the hole in the center.

In fact, everything is ready, you can connect to the receiver or wind the antenna connector on top. Who needs what.

As you can see there is nothing difficult, but for those who do not quite understand, I present a video version.
