Product introduction
The N interface type lightning protection device is suitable for
the lightning protection of the coaxial antenna feeder lines such
as mobile base stations, radio transmitting and receiving devices.
The product is in line with relevant national and industry
standards, and is strictly controlled according to the ISO9001
quality assurance system. It has beautiful appearance, convenient
installation and wiring, simple maintenance, impact resistance and
corrosion resistance. It can work steadily in a bad environment for
a long time. The working frequency range is wide, the standing wave
and insertion loss are small, the output protection voltage is low,
the response speed is fast, and the service life is long.
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.

Use of attention
1. The side of the lightning arrester has a earthing screw ring,
which can be inserted in a thick copper wire and pressed hard and
pressed with the tigers forceps. Then the other end of the copper
wire is connected to the roof of the building. The contact must be
sufficient.

to 95% (25 C) at an altitude of less than 3km;
3. lightning arrester should be connected to the feeder line and
installed near the protected equipment.
4. this product for N interface does not apply to the external
interface
