Relay station outdoor antenna lightning protection SMA interface
antenna signal arrester
Product introduction
The SMA 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. With beautiful appearance,
convenient installation, easy maintenance, impact resistance and
corrosion resistance, it can work steadily in a relatively bad
environment for a long time. It is suitable for all kinds of radio
frequency transceiver systems, wireless network signal
transmitting, satellite TV receiving equipment and monitoring
signal wireless transmitting and receiving equipment.
Product features
1. extremely low stationed Bobbi, ensure that the lightning
arrester does not interfere with the normal operation of the
system.
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. lightning arrester should be connected to the feeder line and
installed near the protected equipment.
2. this product needs no special maintenance. When the system
fails, 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. identify the input / output interface identifier of the
lightning protector, input the external line and output the
connection device.
4. this product is not suitable for the interface of the SMA type
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.
Company profile
Zhejiang Thor Electric Co., Ltd is committed to meeting the
requirements of the European Union’s Waste Electrical and
Electronic Equipment (WEEE) directive. This directive requires
producers of electrical and electronic equipment to finance the
take-back for re-use or recycling of their products placed on the
EU market after 2005.
