The diamond CA-23R/CA-23RP coaxial arrester lightning arrester SMA
interface relay platform platform outdoor antenna
Brief introduction
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
Product features
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.
