High frequency coaxial protection device N interface type lightning
arrester coaxial lightning arrester outdoor antenna
The N interface lightning protector is a design of lightning
protection applied to the antenna feeder system based on the
relevant standards. Between the communication equipment and the
coaxial cable joint or the two communication equipment, it can
effectively prevent the damage of the transient overvoltage formed
by the lightning induction to the communication equipment. It is an
ideal protection device for all kinds of communication equipment
with beautiful appearance, easy installation, easy maintenance,
impact resistance and corrosion resistance, and can work steadily
in a bad environment for a long time.
1. the solid and conductive metal shell has a good shielding
effect, so that the signal is free from external interference.
2. advanced production process and beautiful appearance
3. built in replaceable gas discharge tube, easy installation and

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
Use of attention
1. this product needs no special maintenance. 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
2 .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
3. lightning arrester should be connected to the feeder line and
installed near the protected equipment.
4.The N type interface is not applicable to the external interface
