500V 10KA Surge Protector With Coax Protection , UHF Antenna Surge Protector / Lightning Arrester

Coaxial lightning arrester outdoor antenna UHF antenna interface signal lightning arrester

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.

Product features

Product specification

Brief introduction

The UHF interface lightning protector is a design of lightning protection applied to the antenna feeder system based on the relevant standards. The shielding enclosure, with high quality and high speed overvoltage protection device, has high effective defense function for the lightning impulse induced on the feeder line. It is installed between the communication equipment, the coaxial cable joint or the two communication equipment, and can effectively prevent the damage of the temporary overvoltage formed by the lightning induction.

Use of attention

1. lightning arrester should be connected to the feeder line and installed near the protected equipment.

2. 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 it is restored to the state before use, the lightning arrester has been damaged and must be replaced immediately.

3. when a signal transmission failure occurs on the line, we should find out the reason. If the lightning protector is damaged, the lightning protector will be changed immediately.

4. the product is UHF type interface, which is not suitable for other interfaces.
