Installation (sharing my experience).

You have become acquainted with the various types of television over-the-air antennas. You can independently choose the antenna that best suits your conditions for receiving a television signal. Remainsinstall antenna and you need to do this correctly, because otherwise all your efforts may be in vain. The antenna installation process will include several steps:

Antenna assembly.

When purchasing an over-the-air antenna, you will receive the manufacturer's instructions, which describe the assembly process, connecting the antenna and installing the antenna. Typically, antenna assembly does not cause any problems. But let's pay attention to some points. Many antennas are made using plastic elements; these elements can be attached either using latches or screw connections. Therefore, you should assemble carefully so as not to break the plastic fasteners or crush the fastener due to over-tightening the threads.If there are exposed contact connections on the antenna, seal them with caulk or play dough (I usually use automotive grade play dough). Carefully inspect all fastening connections. If the antenna is active (with a television signal amplifier), you need to check the qualityamplifier connections . If there is any damage or poor quality of assembly, if necessary, eliminate any defects noticed,this will help you avoid problems during further operation.

On some active antennas, amplifiers are not installed directly by the manufacturer, so we install it ourselves. For example, such antennas are common-mode antennas, popularly known as “Polish antenna ”, “ antenna Array" The antennas are equipped with an amplifier-various modifications.The amplifier installation process itself S.W.A. simple to the point of impossibility, but I have repeatedly had to (when calling a client who was tryinginstall the antenna yourself and failed to cope with this seemingly simple task) to meet with incorrect installation such amplifiers.

Antenna connection

The photo shows an option,when the amplifier is installed correctly, and the option is incorrect

SWA installations.

Wrong Correct

The amplifier has contact pads to which the antenna waveguides are connected. If the amplifier is installed incorrectly, its input remains unconnected; naturally, the signal from the antenna does not reach the amplifier input,antenna doesn't work . You can spend time installing the antenna, but the result will be negative, you will have to redo the work, and you may need to replace the amplifier, since very often when the amplifiers are connected incorrectly S.W.A. fail. We will assume that the antenna assembly has been completed and everything has been done correctly.

Antenna cable connection

When describing methods for connecting an antenna cable, I take examples of connecting antennas that are mass-produced.For various small-scale and homemade antennas connections may be completely different.

There are mainly two connection methods used to connect the antenna cable.

1. Clamped.

2. Special Fconnector

Let's consider both connections.

Clamped.

This type of connection is found on antennas where an amplifier is used S.W.A. . The cable in the antennas is connected to the clamp“Delta” made in St. Petersburg andRostov on Don. Therefore, let's consider this connection method using these antennas as an example.On antennas from other manufacturers, the clamp connection will be little different.

Clamp connection with spaced contacts.

This connection is typical for an antenna"Delta".

To connect the cable, you need to remove the top layer of insulation from it.

Under the insulation is the cable braid and foil.The foil must be removed and the braid twisted into a flagellum. If the cable is of high quality and the braid is made of copper, tin the cable with tin solder to make it easier to crimp it with a contact clamp when connecting.The central core of the cable can be crimped with a terminal clamp without modification. If you are “friendly” with a soldering iron, I advise you to additionally solder the cable braid and the central core to the contact clamps, this will be more reliable.

If the cable braid is made of steel, there is no need to tin it; for ease of connection, crimp it with a sleeve for a stranded electrical wire.

Connecting the cable to type terminals S.W.A..

Personally, I like this method of connecting the cable much more than the previous one. There is no need to worry about maintaining polarity; with this connection it is impossible to make a mistake. The cable is securely crimped with a fastening bracket, which gives additional strength to the mechanical connection of the cable to the antenna. The photo shows how to prepare a cable for connection to terminals of the type S.W.A. I would like to draw your attention to connecting the braid. The contact pad to which the cable braid is connected is located under the mounting bracket; the bracket itself is not a contact, and therefore it is necessary to ensure a reliable connection between the cable braid and the amplifier. Also, when connecting, you need to make sure that there is no short circuit between the braiding and the central core of the cable, since their contact clamps are located very close.

Connection with special F connector.

Most convenient way connecting the antenna cable. Reversing the polarity or connecting incorrectly requires effort. The main thing is to prepare the cable correctly. The photo shows how to do this. It is necessary to remove the top layer of insulation.

P connecting the antenna power supply

For active antenna or plug for passive (). The antenna plug is simple in design and I will not consider it; we will consider connecting a special antenna power supply.For all types of active antennas, in which the amplifier is located on the antenna itself, exactly the same power supplies are used.Before installing the antenna, I strongly recommend checking that all connections are connected correctly. Make sure the amplifier and power supply are working.To do this, you need to plug in the power supply. The control LED on the power supply case indicates that everything is fine, there is no short circuit in the cable connection, otherwise you will have to check your operation.If you plan to install the antenna on a high mast, check the functionality of the amplifier. Try to tune in to the television channel before installing the antenna; if the signal passes through, even with fading, this indicates that the amplifier is working. To be sure of this, you need to turn off the power supply from the outlet; the television signal should disappear and when you turn on the power supply, it should appear again.

Installing the antenna on a wall bracket or mast.

After assembling and checking the functionality of the antenna, all that remains is to fix it on a bracket or install it on an antenna mast; the antenna is adjusted to the maximum signal level. Installing an antenna is a responsible job, especially when the antenna is installed on a mast. Always try to complete the job safely for yourself and others. Consider all options for attaching the mast and guy wires. on a mast or bracket, I will not describe in detail, since there are too many options for one article.

I will give Special attention to such a question -“ Grounding the TV antenna.” Television terrestrial antennamust be grounded. Each commercially produced antenna has a special clamp for grounding. Why do you need to ground the antenna?There is only one answer: for a thunderstorm - safety. Of course, if lightning strikes an antenna, there is no guarantee that grounding the antenna will save your property.I personally saw what was left of the TV after a lightning discharge hit its antenna, which was installed on a steel mast. The charge passed through the antenna cable, literally turning it into a thin sintered cord. It pierced the body of the TV, incinerating the radio components in it and passing through the bedside table, it went into the floor. Not a single living creature was harmed.Of course, most of the discharge energy was absorbed by the antenna and the metal mast, through which all the energy went into the ground. It is unknown what would have happened if the antenna was mounted on a wooden pole and had no grounding.Another important function of antenna grounding is electromagnetic pulse protection. A television signal amplifier installed directly on the antenna may fail during a thunderstorm, even if the storm front goes sideways. Very powerful electromagnetic pulses from lightning discharges damage the semiconductor radio components of the antenna amplifier.In this case antenna grounding very effective.If the antenna is installed on a wooden pole, be sure to ground it with any wire (copper, steel, aluminum). It is not necessary to arrange a thorough grounding by burying metal strips in the ground or arranging a grounding loop.It is enough to drive a metal pin approximately 70 cm into the ground.This is quite enough to protect against electromagnetic pulses, and will save you from the need to dismantle the antenna and replace the amplifier.

If you have any questions, ask them.

Today, our televisions are no longer very similar to television receivers of the last century, which only knew how to show something, and at the same time received exclusively an analog signal. What about today? This can be said to be a whole complex of capabilities and abilities. Work with analog and digital signals, the ability to play video and audio signals from universal inputs, the ability to play video from the Internet and even in some cases play games and work with applications from the same. In general, it’s not for nothing that some of them have a proud prefix to their name – SMART, which means skillful. But in this article we would like to talk not about the success of bourgeois companies, which we still have to chase and chase, but about the fact that even the most modern TVs, having Wi-fi and Bluetooth in their arsenal, still need wires. And the most necessary cable for them, as many years ago, is a coaxial television cable. It is with the help of this cable that analog and digital signals are transmitted, that is, a signal with the carrier frequency of the television channels that we watch. And here the most relevant procedures for connecting a cable to a TV will be selecting a cable, cutting it, installing plugs and extending the cable. It is these simple operations that we will talk about in our article.

Selecting a television cable for the TV and its labeling

The first thing you need to pay attention to is the quality of the television cable. It will depend on it how confidently, clearly and without interference or loss the signal is transmitted. If it is an ordinary wire, then after 2-3 meters there will be nothing left of your useful signal, but there will be a lot of interference. All this is due to the peculiarity of the propagation of high-frequency waves, with the help of which the television signal is actually transmitted. A feature of the propagation of such a signal is the manifestation of the skin effect, when the signal propagates over the surface of the conductor. But this is a voluminous and separate topic, so it deserves a separate article, but that’s not about that now.
Well, the second thing is the correct connection of all the plugs, which we have already discussed.
So let's go back to the first one. What does the “correct” television cable mean? This is a cable for which the wave impedance at the operating frequency (up to 2.15 GHz) is 75 Ohms. Most often, such cables are labeled as COAXIL CABLE 75 OHM. Thus, cables of the following brands can be used for a TV: RG 6U (index possible), SAT 50, SAT 703B and DG 113. The names of the cable brands are given in accordance with the improvement of their performance characteristics.
Usually the cable has a manufacturer's marking, the name of the cable, its resistance, meterage and year of production. Now that the cable has been selected, let's proceed directly to the process of connecting it to the TV.

How to connect the antenna plug to the cable

Let us say right away that connecting a cable to a plug or a plug to a cable is not difficult. You can do all this yourself, without involving a specialist. However, the fact that we decided to examine this issue and present it to your judgment is a kind of confirmation of this. Well, let's start in order.
First you need to cut the cable, that is, properly remove the insulating braid.
There are two ways to cut the cable, namely, wrap the shielding braid back or simply cut off the insulation. And then you can screw on the plug itself. Examples of braid cutting are shown in the photo below.

Without bending the braid...

Now the same thing, but with a clear example and with bending the braid.
Cut the braid lengthwise with a sharp knife. Then we cut the braid around the perimeter of the cable. We wrap the braid back so that the next insulating layer is exposed. Here it must be said that the shielding foil is in some cases coated with polyethylene to give the foil strength. At the same time, it is almost impossible to strip polyethylene from the foil. It is also unlikely to burn him. This means we bend the foil back, towards itself, or cut it off altogether. Leaving only the metallic cores of the braid. At the same time, we also clean the central conductor.

Now screw the plug onto the cable. We bite off the central core in place. Its protrusion will be 4-5 mm beyond the union nut. Now, using a nut, screw on the plug itself.

It should be noted here that the plugs are different. Whether straight or curved in the shape of the letter L. They are also called F-shaped plugs. Their functionality remains unchanged, except that each specific plug is used for an individual and easy-to-use variation. If it is more convenient for you to use a specific option, then choose that one.

At the same time, you will not lose anything in performance.

Possible plug options for connecting to cable and TV

Here it is necessary to say that in nature there are a great many variations of plugs.

In the USSR there were plugs that had to be soldered to the cable. And there are also craftsmen who try to stuff, there is no other way to say, a cable into a TV socket without a plug at all. But all this can already be called rudiments, relics, anachronism. In general, this is not worth your attention. Moreover, it is easy to break the socket of an expensive TV, but replacing it will be more difficult.
In this connection, there will be recommendations to use only specialized and modern plugs.

How to extend a TV cable

If you need to extend the cable, it is simply not long enough to connect to the TV. Here it is necessary to act by analogy with the first option. We strip the two ends of the cable and screw on the shank with the union nut. Next, we connect the shanks on the cable to each other using an adapter coupling.

There are also options when you need to connect several TVs. Or you need to connect from the junction box. But here we will not consider this option, since this will turn out to be a mishmash, and not a thematic article. It is better to highlight this topic in the material of our other article.
Another way to extend the cable. It is noteworthy that the connection is made using soldering, which essentially has two advantages. First, you don’t have to spend money on consumables in the form of plugs. Secondly, the signal is practically not lost with such a connection. You can make a dozen connections without any signal loss. So the cable connection algorithm is as follows.

Which plug is best to choose for installing on a cable and connecting to a TV?

Since we have decided to give you recommendations on which plug is better, here we need to motivate our decision. And it all starts simple. Since we need to transmit a signal, and it is transmitted through conductors, it is best to use metal plugs, that is, from the first option for installing the plug given above. This plug is easy to install and does not require soldering or complex tools for installation. This plug is rigid and yet ensures optimal signal transmission. All the advantages are obvious.
In principle, if you come to a store, then a competent, qualified seller will offer you exactly this option; if he does not have the installation, he will sell you another product.

There may be many reasons for extending the television cable, for example, moving the TV from one room to another or replacing some part of the wire due to damage.

To perform this action, you need to understand how to extend the television cable so that it functions and the image quality does not suffer.

Knowing the rules for cable extension plays an important role in terms of saving money, because it is much cheaper than completely replacing it with a longer version.

To extend the antenna cable for a TV with another piece of coaxial wire, you can use several methods:

• a standard extension cord that increases the length of the existing wire by 2.5 – 20 meters, but its cost is not low;
• use of special F-sockets for connection;
• extend several cables through the splitter;
• perform soldering to connect the television wire.

This should be done correctly, since the installation of a television cable in the Russian Federation requires a proper characteristic impedance of 75 ohms.

The quality of the outer braid plays an important role; it must have extreme elasticity.
In addition, in order to avoid loss of image quality, it is necessary to choose products with an internal dense braid that is guaranteed to transmit a continuous signal.

The braid is made of several materials, which determine the price of the cable.

The dielectric material that performs the functions of insulation is not significant, it is mainly polyethylene, it contains foil - the screen and the material of the braid itself:

• with copper cable - expensive, but high quality;
• aluminum – does not represent value in the sense of characteristics;
• Stainless steel – balance between price and quality.

The signal attenuation parameters in terms of length and frequency must be extremely low.

How to lengthen by twisting

This is an unreliable method of extension, since during application, contact may be lost at the twisting site due to oxidation, which deprives high-quality signal transmission and the aesthetic appearance of the cable as a whole is lost.

To make an antenna for digital TV by twisting, you can use two options:

• twist the central cores together instead of soldering, thereby lengthening them;
• we strip 45 - 50 mm along the outer side, and up to 25 mm along the inner side and twist the braid in pairs - the central wires and screens, and perform insulation at the place of twisting.

Soldering

This cable connection method is optimal, reliable and inexpensive; to apply it follow the following algorithm of actions:

• use a knife to remove the outer sheath of the television wire to a length of 5–6 cm;

Important: the shielding braid remains intact.

• then the outer material and the screen are turned away;
• the central core is cut to 20 mm;
• on the one hand, the outer insulation is cut to a length of 10 mm;
• the ends of the central core are tinned and it is bent at an angle of 45 degrees;
• the other connection cable is processed in the same way.

• The central cores are soldered using the overlapping method, after which tin drips should be removed with a file or soldering iron;
• the soldering area is turned off with a piece of the remaining insulation on the central core and secured with electrical tape;
• the foil is screwed back into place;
• for reliability, the screens can be processed by soldering;
• cover the junction with the previously bent outer conductor;
• after which the insulation or closure is carried out with a previously applied heat-shrinkable tube, which is heated with a hairdryer.

Important: the foil has insulation on the inside, so when using it, the material is placed on the outside inside out.

Via splitter

Can be extended using a splitter. This device is necessary to be able to use an antenna for several TVs at once.

The crab is a rectangular box with one IN input and several OUT connectors. To connect it you need F-connectors or TV-plugs.
Inside, the splitter has a ferrite ring with windings or, in the budget version, resistors; thanks to these components, the signal is evenly distributed between the outputs, so there is no need to modify the crab.

If there is a need for more than 4 outputs, an active splitter with an amplifier is used.

To use this option for connecting and extending the cable, it must be rigidly fastened from outside to the plane, that is, it must be tightly secured in a horizontal/vertical position.
In the case of connection using a splitter, a cable prepared in advance from the antenna is attached to the input, and a segment coming from the TV to the output, and then using of this device You can branch the signal throughout the room.

How to extend through an adapter

This option is the simplest, it involves the use of F-adapters.
To use it, it is also important to follow the sequence of actions:

• remove 30 mm of the outer insulation from the length of the television wire;
• wrap the braid in the opposite direction, but because the foil is covered with insulation, bend part of the screen back;
• so that the central wire does not come into contact with the dielectric, strip it by 10 mm, but it is important not to damage it;
• then the adapter is screwed through the foil, while the core should protrude by 0.5 mm, the unnecessary remainder is cut off;
• then you need to perform similar actions for the other end, followed by screwing them into the socket.

Conclusion
In order for the cable to serve for a long time, it should not intersect with electrical wiring or a phone charger, which can interfere with high-quality signal reception; you should not twist it or bend it at a right angle.

Use only factory-made cable clamps, make sure when using a splitter that there are places for fastening, and also correctly connect the television wire in one of the given options, which will ensure its long-term operation in the future and you will not have to think about how to lengthen it.

Often the cause of a malfunction of a television device is damage to the antenna cable or the plug connecting the TV device to the periphery.

After reading the tips presented in the article on choosing and connecting a plug for a TV antenna, the user will be able to independently repair the indicated breakdown.

If previously, to connect an antenna cable to a television plug, it was necessary to resort to soldering or select peripherals with suitable connectors, but now the user can assemble the necessary structure using available tools.

Modern manufacturers of TV components make plugs according to the international F-standard, which is a kind of bushing that is screwed onto the antenna wire.

Which antenna plug is better?

For connection with, the F-plug is best suited, among the main advantages of which are:

• the presence of a shielding braid around the central core - the braid serves to ensure uniformity of wave impedance and prevents additional losses in the quality of the television signal;
• compatibility with any type of television signal - the F-plug works equally well with a digital antenna and cable television;
• ease of installation - any user can handle the connection, as you can verify after reading the following sections of this article.

Since installation of the previous generation antenna plug will require much more effort, only F-plugs, the use of which is more appropriate, will be considered below.

How to prepare the cable

Before installing the F-plug, you must prepare the antenna cable for connection. After removing the old plug from the wire, the user must cut the outer insulation of the wire in a circle - when removing the protective layer, the braid cannot be damaged. The length of the incision should not exceed 2 centimeters.

Next, you will need to bend the insulation in such a way that the TV cable retains its shielding properties: part of the metal “hairs” of the insulation should be hidden only when further connecting the F-plug, and not smoothed to the body of the wire. The compliance of the insulation depends on the manufacturer of the peripheral and the physical strength of the user.

How to connect the antenna F-plug and cable

It is worth saying that since there are three sizes of F-plug, before purchasing a connecting element you need to make sure that the plug and the antenna cable are compatible. Although the sizes vary, each F-plug supports analog, digital, and satellite signals.
There are two ways to attach the F-plug to a television cable: the first involves wrapping the shielding braid, and the second involves cutting off the sheath at the point of contact of the periphery.

The first option is more reliable, but requires much more effort and accuracy from the user.

If you cannot wrap the braid for one reason or another, you must follow the instructions below:

1. Cut part of the television cable. The user will need to cut a few centimeters of the outer sheath of the cable so as not to damage the braided screen. To carry out this operation, it is recommended to use a sharp stationery knife and not apply a large number of physical strength.
2. Bend back the protective shell. When the wire is “bare”, you will have to remove the excess part of the protective sheath.
3. Removing an additional layer of wire protection. Depending on the cable type, the user will need to remove the copper braid or aluminum foil at this stage. It is worth noting that some wires are protected by both a copper and an aluminum layer.
4. Return half of the previously folded layer of foil back into place. Interestingly, during production, to strengthen the structure of the wire, a layer of polyethylene is applied to aluminum foil, which is almost impossible to clean. Once the cable is connected to the plug, the plastic can create and interfere with the transmission of the television signal - to avoid possible loss of picture quality, the user needs to place the conductive part of the wire on the outside.
5. Equalize the diameters of the connected antenna cable and F-plug. Sometimes the hole in the internal thread of the F-plug has a larger diameter compared to the “bare” end of the cable - to eliminate the difference in diameters, you will need to wrap 2-3 layers of insulating tape on the wire. It is important to note that after this operation it will be necessary to remove part of the homemade insulation from the central conductor of the cable.
6. Screw the metal part of the F-plug onto the antenna wire. To avoid stripping the threads of the elements being connected, screwing should be done by hand rather than using tools.
7. “Bite off” the central core of the wire. It is important to say that as a result the conductor should protrude by 2-3 millimeters.
8. Screw the “head” of the F-plug onto the assembled structure. Next, the user can start connecting the antenna to the corresponding jack on the TV.

If, when connecting the F-plug to the television socket, the antenna cable will have to be bent at an angle of more than 70 degrees, then in order to avoid chafing of the wire, it is recommended to use a plug of an angular design, which differs from the usual one only in its external shape. The installation process for straight and angled plugs is similar.
If the user plans to use an old type of plug, then it is likely that when connecting the elements it will also be necessary to transfer the plastic cover from the plug to the cable. To connect a non-certified plug to the wire, you will need a soldering iron.

Conclusion

Now the owner of the TV device knows how to correctly connect the antenna F-plug to the cable network. The process of repairing an old wire is not anything complicated - even a user who is far from repairing electrical equipment can cope with restoring a television system.

It is difficult to imagine modern housing without television. For stable reception of a TV signal, a TV antenna is required, connected to the TV with a special TV cable. The average service life of such a wire when properly connected is 10 years. Temperature changes, room renovations, rearrangement of furniture and other unfavorable factors can reduce the service life of the cable.

Wire connection methods

Some people turn to specialized workshops to install a TV antenna, but most home craftsmen prefer to do this work themselves. It is not particularly difficult and can be done by anyone who has basic knowledge of electricity and understands how to select and install an antenna cable for a TV.

There are several ways to connect antenna wires to each other:

1. Soldering (using a soldering iron with tin and rosin).
2. Twisting (mechanical twisting of the free ends of the wire).
3. F-nut connection (simple and securely fixed threaded contact).

Due to the complexity of the first two options, we will consider the most current, easily accessible and time-tested method of connecting a cable using a special connector - an F-nut. Although there are two more ways to solve the problem, they require much more time and effort, without guaranteeing one hundred percent success in terms of high-quality signal reception. The first method additionally requires skills in handling a soldering iron.

Stages of work completion

Before you start working, you should disconnect the television receiver from the power supply. Then you need to carefully inspect and feel the antenna wire for wear on its outer insulation. If there are microcracks and peeling in certain areas, it is advisable to completely renew them. After this, you need to measure the length of the TV cable that requires replacement or extension and write down the indicators. A large number of docking nodes is extremely undesirable, since each of them affects the quality of the received signal. The best option is to replace a single piece of antenna wire from the divider to the TV.

When extending the cable, it is better to create a reserve of its length for a possible change in the location of the television receiver in the future, and roll the excess into a ring of small diameter and secure it by wrapping it with adhesive tape.

Before going to buy materials for an antenna, it is advisable to cut off a small piece of the existing wire as a visual example for selecting a similar one. This will help you choose the right cable if you don’t know its letter or number designations.

Explaining how to choose a cable for satellite television, experts advise choosing it according to the presented fragment or depending on the brand of television receiver. You also need to decide in advance on the method of laying the antenna wire (open or hidden).

At open method The wire is attached to any flat surface using clips pre-fixed to the wall or ceiling. In this case, light cables with protection or flat wires made of copper or aluminum with rubber insulation are used. It is also advisable to use plastic cable channels with a locking lid, in which, in addition to the one in question, other wires are placed: telephone cord, power supply to a computer or air conditioner, etc.

When using hidden installation, the cable is mounted in a strobe under a layer of plaster, floor or baseboard. With this method, brands such as APV, APPV, VARN, APS, etc. are used. It requires a slightly thicker layer of external wire insulation. Having purchased the required quantity of cable of the required quality and decided on the installation method, you can begin installing the antenna cable.

Structure and installation order

To understand how to connect the antenna cable to each other, you need to get an idea about its general structure. Experts call it a special coaxial wire for transmitting a TV signal, image and sound. There were two main dwellers in it:

• central (receives video and audio signals);
• shielding (protects against magnetic and radio interference).

A coaxial television cable consists of four components. The main one is the central rigid wire (it is copper or aluminum, filled with continuous insulation made of polyethylene or fluoroplastic). This wire is wrapped in a thin braid of copper or aluminum. The presence of insulating polyethylene prevents the two main wires from contacting each other, which is a critical condition for high-quality signal reception. The final layer is the outer insulation, which protects the cord from mechanical damage. The most commonly used wires are RG-6, SAT-50, SAT-703.

To understand how to connect a TV cable together, you must follow the instructions:

If the F-nut does not fit tightly, you need to crimp it with pliers directly on the wire until it is securely fixed.

Splitter device and principle of operation

If the goal is to divide the feed signal into several receivers, use divider or "crab".The original name of this device is splitter. It is a box with connectors for connection with an F-nut.

The inscription IN on the connector is always the same on the divider and is used for the signal supply cable. The inscription OUT is intended for cables going to receivers (there may be several of them). The number of connectors labeled OUT should always be one more than TVs, that is, for two TV receivers - 3 connectors, for three - 4, etc. It is undesirable to leave empty connectors, as this leads to deterioration of the signal due to loss of resistance in the cable. But if the task is to divide the cable into 4 or more TVs, you should connect special splitters with amplifiers.

Before connecting the receiver, all that remains is to figure out how to properly connect the antenna cable to the plug, that is, directly to the TV. A nut connection is also used here. The plug can be straight or angled. Which one to choose does not matter, since there are no fundamental differences between them. Sometimes there are cases when the straight plug (used most often) is inconvenient to connect due to external interference.

After making sure that all the necessary elements of the television antenna are securely connected and that they are resistant to external mechanical loads, you can turn on the power and begin tuning the TV. Independent work on the correct connection of a coaxial antenna wire is not an extremely difficult task and is quite within the capabilities of a person who wants to learn something new.
