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.
