The diamond CA-23R/CA-23RP coaxial arrester lightning arrester SMA interface relay platform platform outdoor antenna
The antenna feeder is also known as antenna feeder, surge protector, antenna feeder and lightning feeder, mainly for lightning protection of feeder. For wireless communication, mobile base station, microwave communication, radio and television broadcasting coaxial antenna signal lightning surge protection
1. low capacitance, inductance design, superior transmission performance;
2. high transmission frequency, small insertion loss;
3. the low attenuation coefficient ensures that the lightning arrester does not affect the system performance.
4. does not apply to the interface other than SMA
Use of attention
1. when the signal transmission failure occurs, we should find out the reason. If the lightning protector is damaged, the lightning protector will be changed immediately.
2. in order to reliably prevent thunder and lightning, we can connect each antenna output terminal and the input terminal of the protected device to a lightning feeder. In areas where lightning is less, only one antenna can be used without amplifier.
3. The wire on the lightning arrester is welded as short as the 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.

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.
