Relay station platform outdoor antenna lightning protection type N
interface antenna signal lightning arrester
Product introduction
The N interface lightning protector is a design of lightning
protection applied to the antenna feeder system based on the
relevant standards. The products meet the relevant national and
industry standards, and are strictly controlled according to the
ISO9001 quality assurance system. It can work steadily in a bad
environment for a long time. The working frequency range is wide,
the standing wave and the insertion loss are small, the output
protection voltage is low, the response speed is fast and the life
is long. It is suitable for the lightning protection of the coaxial
feeder signal line of the mobile base station, radio transmitting
(receiving) and other equipment.
Product features
1. resistance to impact and corrosion resistance
2. core components have been strictly screened and selected
internationally famous brand products with superior performance.
3. the low attenuation coefficient ensures that the lightning
arrester does not affect the system performance.
Use of attention
1. please recognize the interface and the way of connection
2. in order to reliably prevent thunder and lightning, we can
connect each antenna output terminal and the input terminal of the
protected device to a lightning feeder. In areas where lightning is
less, there can be only one antenna without amplifier.
3. - 40 ~ 85 temperature C; relative humidity: less than or equal
to 95% (25 C) at an altitude of less than 3km;
4. this product for N interface does not apply to the external
interface

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.
