TNC type interface antenna, coaxial arrester, relay, base station arrester, outdoor antenna.
Product description
The surge protector prevents the damage caused by the feeder line induced lightning overvoltage to the antenna and the transceiver. It is suitable for satellite wireless communication, mobile base station, microwave communication, radio and television and other coaxial feed system signals, which are installed in the lightning protection zoning LPZ0A-1 and after the continuation zoning. The product is shielded enclosure and built in high speed and over voltage protection device. It has an effective defense function for lightning induced high voltage impulse on the antenna feeder line.

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
1. multilevel protection and large circulation capacity
2. core components have been strictly screened and selected internationally famous brand products with superior performance.
3. built in fast semiconductor protection device, with fast response speed.
Use of attention
1. please recognize the interface and connection mode.
2. identify the input / output interface identifier of the lightning protector, input the external line and output the device.
3. grounding lines should be short, thick and straight, so as to reduce the influence of distributed inductors on the ability of lightning electromagnetic pulse.
4. Not applicable to interfaces outside TNC
