The diamond CA-23RP arrester lightning arrester relay station platform outdoor antenna signal protection
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. extremely low stationed Bobbi, ensure that the lightning arrester does not interfere with the normal operation of the system.
2. the solid and conductive metal shell has a good shielding effect, so that the signal is free from external interference.
3. limited voltage is very low

Brief introduction
The sky feed arrester is installed between the communication equipment, the coaxial cable joint or the two communication equipment, which can effectively prevent the transient overvoltage caused by the lightning induction to the communication equipment. The device adopts the 1/4 lambda short route principle. The insertion loss is small, the flow capacity is large, the residual pressure is low, and the signal other than the working frequency is short circuited. It is an ideal protection device for all kinds of communication equipment.
Use of attention
1. in the use of outdoor antenna lightning protection device must pay attention to rain, don't let the internal corrosion damage caused by rain water immersion.
2. There is no special maintenance for this product. When the system fails, 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. 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.
