Antenna coaxial arrester type FA10 diamond CA-23RP/RS instrument interface antenna lightning protection
Product description
The FL10 interface lightning protector is a design of lightning protection applied to the antenna feeder system based on the relevant standards. The product is in accordance with relevant national and industry standards, and strictly controlled by the ISO9001 quality assurance system, easy to install connection, simple maintenance, impact resistance and corrosion resistance. It can work in a relatively bad environment for a long time, using the 1/4 lambda short route principle, small insertion loss, large flow capacity, low residual pressure, and working frequency. The signal outside is short circuited, and it is an ideal protection device for all kinds of communication devices.
Use of attention
1. the product is FL10 type interface, which is not suitable for other interfaces.
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. this product needs no special maintenance. When the work of the system fails, the lightning arrester can be dismantled and rechecked. If the system is restored to normal, the lightning arrester has been damaged and must be replaced immediately.
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. low capacitance, inductance design, superior transmission performance

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.
