F interface type antenna coaxial lightning arrester diamond CA-23R outdoor antenna lightning protection device
Brief introduction
The F 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.

Use of attention
1. identify the input / output interface identifier of the lightning protector, input the external line and output the connection device.
2. 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.
3. the wire on the lightning arrester is welded to the shortest grounding wire (the wire area is not less than 2.5mm2), the other end is connected to the grounding bus of the lightning protection system, and the grounding resistance is not more than 4 Omega.
4. this product for F interface does not apply to the external interface
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.
