Coaxial lightning arrester outdoor antenna FL10 antenna interface
signal lightning arrester
Product Details
The FL10 interface lightning protector is a design of lightning
protection applied to the antenna feeder system based on the
relevant standards. It is suitable for all kinds of radio frequency
transceiver system, wireless network signal transmitting, satellite
TV receiving equipment, and monitoring signal wireless transmitting
and receiving equipment. 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.
Product features
1. the solid and conductive metal shell has a good shielding
effect, so that the signal is free from external interference.
2. built in replaceable gas discharge tube, easy installation and
maintenance.
3. limit voltage is very low

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 product is FL10 type interface, which is not suitable for
other interfaces.
2. lightning arrester should be connected to the feeder line and
installed near the protected equipment.
3. 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 being restored to the state before use,
the lightning arrester has been damaged and must be replaced
immediately.
4. 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.
