What Should Be Paid Attention To When Installing Outdoor Tv Antenna?

Like any antenna, a TV antenna is made of metal. The electromagnetic wave carrying the TV signal will produce a small current in the antenna. The TV amplifies the signal and chooses to carry visual and sound information. So what should we pay attention to when installing an outdoor antenna?

As a professional Tv Antenna Pole Towers exporter, next, we will tell you the answer.

Factors

1. Each deflector, reflector, and vibrator of the antenna must be parallel to each other and located in the same plane. Each deflector and reflector can be installed on the same metal crossbar and must be perpendicular to the metal crossbar.

2. Generally, the antenna shall be kept horizontal and shall not tilt forward or backward.

3. The Tv Antenna shall be far away from power lines, telephone lines, broadcast lines, and other electrical equipment to avoid electromagnetic interference and electric shock accidents.

4. The Tv Antenna shall be erected as high as possible to improve the receiving effect. Pay attention to the stable and firm installation. To prevent the antenna from shaking in strong wind, the iron wire can be used as the stay wire of the antenna stay rod. Note that the stay wire cannot be connected with the deflector, reflector, and vibrator.

5. The shielding of tall buildings shall be avoided between the antenna and the TV transmitting station.

6. Try to shorten the feeder length and avoid feeder turning as much as possible.

7. When the antenna feeder is introduced into the room, it is necessary to avoid opening the city power supply line. If strip parallel feeders are used, they shall be twisted every half meter to reduce the interference level.

8. The Tv Antenna Pole shall have sufficient mechanical strength to ensure that the antenna will not swing in case of wind. The connection of the feeder must be firm and reliable.

9. Lightning protection measures must be considered for Outdoor Tv Antenna Pole.

10. The TV feeder must match the antenna. If not, an impedance matcher must be installed. The TV feeder shall give priority to the selection of low loss TV special 75Cable to reduce the attenuation of TV signal in transmission.

11. The TV feeder is led down from the antenna and should be fixed and cannot float with the wind. If the antenna pole is a metal pole, the feeder should be 5-10cm away from the pole and try to fix it. The TV feeder shall be as short as possible and shall not be bundled or knotted.

12. When erecting the antenna, the direction of the antenna shall be adjusted repeatedly to align it with the TV transmitting station to obtain the best effect. The specific method is: first adjust the TV to the best state in comparison, and then two people cooperate. One person slowly and repeatedly rotates the direction of the antenna, and the other person monitors the viewing effect indoors. When the TV image and accompanying sound are both good, fix the antenna together.
