TNC interface type antenna signal lightning arrester outdoor
antenna lightning surge protection
Brief introduction
The TNC interface lightning protector is a design of lightning
protection applied to the antenna feeder system based on the
relevant standards. It is applied to communication station, radar
station, PHS base station, mobile communication base station, GPS
base station, CDMA base station, PHS (PAS) base station, satellite
communication, microwave station and so on. It has high effective
defense function for lightning high voltage pulse induced on the
feeder line, which can prevent the antenna and transceiver caused
by the feeder line induced lightning overvoltage. Damage.

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. 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. core components are strictly screened, and brand products are
selected for superior performance.
Use of attention
1. grounding lines should be short, thick and straight, so as to
reduce the influence of distributed inductors on the ability of
lightning electromagnetic pulse.
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. the product is TNC type interface, which is not suitable for
other interfaces.
