Antenna coaxial arrester type FA10 diamond CA-23RP/RS instrument
interface antenna lightning protection
Product description
The FL10 interface lightning protector is a design of lightning
protection applied to the antenna feeder system based on the
relevant standards. The product is in accordance with relevant
national and industry standards, and strictly controlled by the
ISO9001 quality assurance system, easy to install connection,
simple maintenance, impact resistance and corrosion resistance. It
can work in a relatively bad environment for a long time, using the
1/4 lambda short route principle, small insertion loss, large flow
capacity, low residual pressure, and working frequency. The signal
outside is short circuited, and it is an ideal protection device
for all kinds of communication devices.
Use of attention
1. the product is FL10 type interface, which is not suitable for
other interfaces.
2. please recognize the interface and the way of connection
3. the wire on the lightning arrester is welded to the shortest
grounding wire (the wire area is not less than 2.5mm2), the other
end is connected to the grounding bus of the lightning protection
system, and the grounding resistance is not more than 4 Omega.
4. this product needs no special maintenance. When the work of the
system fails, the lightning arrester can be dismantled and
rechecked. If the system is restored to normal, the lightning
arrester has been damaged and must be replaced immediately.
Product features
1. resistance to impact and corrosion resistance
2. the solid and conductive metal shell has a good shielding
effect, so that the signal is free from external interference.
3. low capacitance, inductance design, superior transmission
performance

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.
