How to improve the reception of a TV antenna

It's unpleasant when a TV antennalittle programs are being made, and even those are in disgusting quality. Particularly offensive, if the worst catch the most interesting channels. Solve the problem by changing the orientation antennas, its replacement or addition by an amplifier.

How to improve the reception of a TV antenna

You will need

  • - antenna amplifier and power supply for it;
  • - Antenna splitter;
  • - Antenna cable for 75 Ohm;
  • - an ohmmeter;
  • - soldering iron and soldering materials;
  • - materials for sealing the hole in the wall.
  • - Antenna connectors;
  • - antennas of various designs.

Instructions

1

Do not use the indoor antenna,if your house is equipped with a collective. Establish a special branching device (CRAB - cable splitter user's household) and with it, draw the signal from the collective antenna to those of your existing TVs that were previously operated with indoor antennas.

2

If it is impossible to use collectiveantenna check if the frequency range of the indoor antenna matches the frequencies of the channels that you are watching. For example, if you prefer decimeter channels, there is no point in trying to take them with good quality with a meter antenna, and vice versa. Telescopic antennas allow not only to change the position of the knees, but also to regulate their length, and one should not think that they should always be advanced completely. The higher the channel frequency, the smaller the length, they should be pushed. Excessive length can worsen Admission as well as insufficient, and it is best to select it by experience.

3

Connect the indoor antenna to the TVdirectly, and through a special antenna extension cord. This will move it around the room. Find the position in which the best reception is provided. Sometimes it is useful to place a video recorder with a tuner near the antenna, and connect it to a television with a long low-frequency cable. This will allow you to isolate yourself from interference if their source (for example, a computer) is located near the TV.

4

In the event that moving the indoor antennaImprove reception failed, use external. Place it on the wall opposite the television center, protect it from atmospheric precipitation, seal the cable entry into the room. In a private house, the best place for an outdoor antenna is the roof. Do not use the outdoor antenna if your home is not in the lightning protection zone.

5

Being in a zone of an uncertain reception of a signaltelecentre, use an antenna with an amplifier. When you purchase a kit from an amplifier and a compatible antenna, fix the board to the two screws that are assigned to it, and connect the coaxial cable to the card itself. On the opposite side, connect to it a special plug, instead of a standard plug, designed to supply power to the amplifier for the amplifier and at the same time to prevent this voltage from reaching the television. This plug, together with the power supply, is supplied with the amplifier.
