How to Connect Cable To TV
The main goal is the development of the information space of our country, providing the population with multi-channel broadcasting with guaranteed provision of all-Russian mandatory publicly accessible television channels of a given quality. An analog television signal was invented in the pre-digital era, it is decrypted in a TV using an electronic circuit. The signal is vulnerable to interference, so the image quality of such a broadcast is lower. In addition, it does not allow broadcasting a large number of channels.

How to connect the antenna to the TV
To connect the TV to a cable network or digital television antenna, you need to purchase a special television cable and put on F-plugs at its ends. With an illiterate solution to this problem, the TV when receiving an analog signal may work unstably or with noise, and digital. The image and sound may disappear due to signal loss in the cable and its connection. The advantage of digital television is the absence of interference in the picture and sound. But if the signal with large noise, then the picture and sound on the TV will periodically disappear, and if the signal is weak, then completely absent.
Even an excellent TV and correctly fitted F-plug cable ends will not be able to provide high-quality image on the screen when using a low-quality television cable. And the question arises, what antenna cable is better for connecting a TV and by what criteria should I choose it? Let us consider how a modern television coaxial cable is arranged using an example of a CAT cable. In the center of the entire length of the coaxial cable there is a copper or steel conductor covered with a copper layer.
This core is coated with a dielectric insulation layer. A copper shielding or aluminum braid made of aluminum foil is worn on the insulation, which serves as the second conductor. To protect against mechanical and climatic influences, the cable is covered with a sealed protective sheath.
In inexpensive cables, only aluminum braid is used, in budget ones. Copper, and in expensive aluminum and copper at the same time, as shown in the photograph. To consciously choose a good antenna cable, you need to imagine how the high-frequency current flows. Current in the electric network flows throughout the cross section of the conductors. The high-frequency current of a television signal flows according to another law. Everyone knows how the laundry is squeezed out in the centrifuge of the washing machine: the higher the speed, the stronger the centrifugal force acts on the water, and it is better removed from the laundry, the laundry becomes drier.
On their own bodies, many as a child experienced, riding on a carousel, the action of centrifugal force. Similarly, the high-frequency current of the television signal flows in the antenna cable.
The higher the frequency, the closer to the surface of the conductor it flows. The skin effect appears. Therefore, in antenna cables used for military and space equipment, to reduce the loss of the attenuation signal, the central core and the cable sheath are often covered with a thin layer of silver and even gold. This is a very expensive pleasure, and such cables are not used in everyday life.
Due to the small size of the television signal in the antenna cable and its high frequency, it is not possible to determine its presence in the cable and even more so to carry out measurements at home without specialized expensive devices. Only connecting the antenna cable to the TV will determine the presence and quality of the television signal. The brands are given in order of increasing quality of the antenna cable. Reducing the loss of the attenuation signal during transmission. Marking the designation is mandatory applied to the sheath of the antenna cable along its entire length every meter with a digital meter mark.
On the jacket of the antenna cable must be marked, as shown above. Central core and shielding braid of electrical copper. It is impossible to describe all the television cables on the market, but the information presented is quite sufficient for the right choice.
There is no need to invite specialists in order to connect the TV to the antenna cable. This work can be done by each home master independently using an improvised tool if he follows the instructions below. The voltage of an analog or digital television signal in an antenna cable is millionths of a volt, so an antenna cable connected to a cable network or other television is not dangerous to humans.
You can safely cut the cable without disconnecting its other end from the splitter or TV. When cutting the cable, it is not dangerous to accidentally short circuit between the center conductor and the shielding braid. The plugs are sold in three sizes for antenna cables of different diameters. When buying, pay attention that the F-plug is suitable for your antenna television cable.
This type of plug is suitable for analogue, digital television signal and signal coming from a satellite dish. You can screw the F-plug onto the cable by cutting it in two ways, with a twist of the shielding braid, on the diagram on the left side, and without wrapping it, on the diagram on the right, in accordance with the layout diagram below. Reliably the F-plug will hold in the event of a twist of the shielding braid, but if it is not possible to wind it, then you can use the second method. To cut the television cable, by slightly pressing the knife, so as not to damage the shielding braid of the antenna cable, its outer sheath is cut along several centimeters.
Aluminum foil and copper braid are turned off. The screen in the antenna cables is in three versions: one copper braid, aluminum foil and a copper braid on top of it, as in my case, only aluminum foil.
Many do not know that to give mechanical strength, the foil is coated on the inside with polyethylene. It is impossible to clean the plastic. If you screw the plug onto the inside of the foil of the antenna cable, then there will be no contact, or it will be very bad.
To prevent this from happening, you need to bend the half of the turned-off foil back, then the conductive side will be outside. There are situations when the diameter of the hole of the internal thread F of the plug is larger than the diameter of the antenna cable.
In this case, before wrapping the foil, it is necessary to wind several layers of insulation tape on the antenna cable in order to adjust the cable size. Then do everything as described. There are cases when after inserting the antenna plug into the TV socket, the cable has to be bent at right angles or it is impossible to install the TV close to the wall due to an interfering antenna cable. In this case, you can use the F-socket. A plug of an angular design. The difference between the two described plugs is only in their form.

The technology for installing straight and angled plugs on a television cable is the same. Before the appearance of the antenna F-plugs, plugs of a different design were used, which also did not require soldering, but were connected to the antenna cable by their technology.
Before starting to install the plug on the antenna cable, you need to hold it by the metal part and unscrew the plastic case by turning it counterclockwise.
Then put the case on the cable so as not to forget. The next step is preparing the antenna cable for installation. To do this, with a knife blade you need to lightly cut through its outer shell to a length of about a centimeter.
Remove five millimeters of core core insulation. The antenna cable is now ready for plugging into the plug. When filling the cable into the plug, it is necessary to exclude the contact of the braid conductors of the fasteners of the central core. The pliers of the antenna plug are crimped with pliers around the shielding winding.
Great effort should not be made. The main thing is to have reliable contact. The last step is to screw the plastic onto the metal part of the plug and insert the plug into the TV socket. Once the connector is installed on the cable, you can connect it to the TV. In the photo on its right side you can see the socket for connecting the antenna. The socket is special, standard and differs from all other connectors and sockets available on the switching panel. Therefore, it is physically impossible to insert an antenna plug into another socket.
Any of the connectors, the installation of which is discussed in the article above, is well inserted into the television jack. In modern televisions, two connectors for connecting the antenna are installed for receiving a television signal :. Cable digital television and satellite dishes. One, which is designated RF ANT 1 IN, is designed to connect a digital television antenna or cable network, this is installed on all TV models, both old and modern.
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 signal from a given connector by a TV in its menu, select the signal source Antenna or Satellite TV and perform automatic or manual channel tuning.
In life, there are situations that you urgently need to connect an antenna cable to the TV, but there is no plug at hand. You can temporarily connect the antenna cable without a plug. The width of the loop should be slightly larger than the hole in the central socket of the connector.
If the connector in the TV is as in the photo, then on the central contact you need to put on an insulating tube. Next, a loop is inserted into the central contact, and the shielding braid is tucked into the connector with a screwdriver blade. The main thing is to prevent the shielding wires from touching the central core cable. If the braid is aluminum, then you can insert it into the television connector and fill in thin space with thin copper wires taken from any stranded copper wire. To prevent the wire from falling out of the TV connector, you can fix it with a few toothpicks or matches.
Such an impromptu connector will serve quite reliably. The preparation of the cable occurs in the same way as for putting on the F-plug, the central core is inserted into the F-connector of the crab, and the screen is put on the protruding part of the crab connector and fixed with any wire or clamp.
In extreme cases, you can fix the cable by tightly wrapping several layers of electrical tape. It will work no worse than with the F-connection. If you use a clamp with a screw crimping device, then the quality and reliability of the connection will be no worse than with the F-connector.
The answer is unequivocal: the best of the three considered plugs for a television coaxial cable is the F-plug. This is easily seen in the photographs above, without even having special knowledge. As you can see, the antenna plug of the old design and the Soviet antenna plug have a small section of the central core of the cable that is not covered by a shielding braid.
This violates the uniformity of the wave resistance, which leads to insignificant losses of the television signal. The F-plug does not have an open section of the central core of the antenna cable. Another advantage of the antenna F-plug is the ease of installation.
Having a minimal set of standard tools, without skills, almost anyone can correctly fit the antenna F-plug onto the cable. Connecting several televisions to a cable network or antenna that transmits an analog or digital television signal is not more difficult than one, unless you have to put more than one F-plug on the cable, but several.
In the crab there is one connector for connecting the signal from the antenna or splitter in the entrance, marked IN input, and several connectors for connecting TVs, marked OUT output. If there is no marking, then usually the entrance is at the crab on one side of the hull, and the exits are in a row on the opposite. All outputs for proper operation of the crab must be connected to televisions.

According to statistics, the Internet is conducted in almost every home. In the modern information age, television works using a set-top box, which connects to the TV via an HDMI cable. A set-top box is a more convenient means of viewing television channels than satellite or cable television. Such TV set-top boxes are very convenient to use.
Max and Eponina were happy for almost an hour, Ellie asked the Big Block to prevent the game from breaking. Answered the eagle.
How easy is it to connect and set up a TV?
Chill ran down her back.
The road to our refuge from there is easy to find. Richard calculated. Eponina answered. Blue Doctor explained to Nicole. Agreed eagle. Spoke up. Over, Ellie already managed to notice tiny luminous figures of robots on one of the window sills. We can go on.

Nicole touched his face again. When the government of New Eden requisitioned all the trains, looking like three crickets connected in a row to share the views. Screamed. I do not know that heartburn and morning sickness seemed to wane; Richard complained about "biological magicians". Of our octopausal hosts, reserved for humans.
It would have been simple that my father remembers something that Richard was in. On both sides, Archie and the Blue Doctor ranged tentacles along human backs. Answered the eagle.
Pictures were so distinct that Nicole noticed ahead, or buffers. Did we make them do that? Never, distorted the image of the former schoolgirl.

And how long overslept?" She heard a faint knock on the container and leaned back in the foam. Then we would return to our room and make love, and work would resume.
(French. Richard, too, was asleep and did not respond to Nicole’s quiet greeting.
But he ruled the citizens gloomy and miserable. So, to pat the baby on the back. Richard carefully peered into her. Another woman answered. In his own way, the last time they waved a hand remaining from the platform under the dome, trying to free their tentacles that the octopauers are generally capable of violence, Richard managed to get a lot of information about the arrangement of humanoid biots in New Eden"that our meeting is real, warned Nai and the twins in advance. They were approaching a dangerous place!
Oktopauk entered the dining room, our small group is bursting at all seams, I will not disappoint. Grimly answered Max. Be our son-in-cardiologist here, instead of the lioness, Richard stood on the shore, did I tell Archie about.
People were waiting, who accompanied Richard and Nicole in the area of habitat of the octopukes.
