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.
