Coaxial lightning arrester outdoor antenna UHF antenna interface signal lightning arrester
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. high transmission frequency, small insertion loss
2. advanced production process and beautiful appearance
3. built in replaceable gas discharge tube, easy
installation and maintenance.

Brief introduction
The UHF interface lightning protector is a design of
lightning protection applied to the antenna feeder system based on
the relevant standards. The shielding enclosure, with high quality
and high speed overvoltage protection device, has high effective
defense function for the lightning impulse induced on the feeder
line. It is installed between the communication equipment, the
coaxial cable joint or the two communication equipment, and can
effectively prevent the damage of the temporary overvoltage formed
by the lightning induction.
Use of attention
1. lightning arrester should be connected to the feeder
line and installed near the protected equipment.
2. when the system fails to doubt the lightning arrester,
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. when a signal transmission failure occurs on the
line, we should find out the reason. If the lightning protector is
damaged, the lightning protector will be changed immediately.
4. the product is UHF type interface, which is not
suitable for other interfaces.
