Lightning arrester type TRS interface antenna surge protector RF coaxial lightning arrester
Product description
The TRS interface lightning protector is a design of lightning protection applied to the antenna feeder system based on the relevant standards. It is suitable for the surge protection of the coaxial sky feed system signals such as satellite wireless communication, mobile base station, microwave communication, radio and television and so on, to prevent the damage caused by the feeder line induced lightning overvoltage on the antenna and the transceiver.
Product features
1. limit voltage is very low
2. installation, easy to use, easy to maintain
3. exquisite workmanship, able to work in bad environment for a long time.
Working principle of product
The lightning protection device is based on the principle of standing wave antenna and lightning wave spectrum design. The main part is a short rod equivalent to the end of the 1/4 wavelength. When the signal is sent out, a part of the impedance is reflected back because the impedance is not fully matched, and the wave will form a standing wave when the wave is superimposed on the incident wave originally emitted. The amplitude of standing wave at each point of the line is fixed first. For the transmission line with terminal short circuit, the terminal is short circuited, so the current is large and the voltage is small. For the signal end, the voltage and the current are small.
That is, the most close to the open circuit of the signal terminal impedance, so the loss is small, but for the lightning wave because of its wide spectrum range, and most of the energy is concentrated in the frequency band below 10HZ, so the short circuit rod is short circuited to the lightning, and will not invade the equipment to cause damage.

Use of attention
1. the joints of most antennas are N type, so the two connectors of the surge arrester are two N heads. One is the N public (the antenna), and the other is N mother.
2. - 40 ~ 85 temperature C; relative humidity: less than or equal to 95% (25 C) at an altitude of less than 3km;
3. when the system fails to doubt the lightning arrester, the lightning arrester can be dismantled and rechecked. If the system is restored to normal after being restored to the state before use, the lightning arrester has been damaged and must be replaced immediately.
