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.
