FL10 Interface Coaxial Cable Lightning Arrestor , Tv Antenna Surge Protector

FL10 interface type coaxial arrester lightning protection antenna outdoor antenna signals.

Brief introduction

The 1. FL10 interface lightning protector is a lightning protection product designed for the antenna feeder system based on the relevant standards. The products are packed with shielded enclosure and built with high quality and high speed overvoltage protection devices. It has high effective defense function for lightning impulse induced on the feeder line, with wide working frequency range, small standing wave and insertion loss, low output protection voltage and quick response speed and effective protection of equipment safety.

Product features

1. the low attenuation coefficient ensures that the lightning arrester does not affect the system performance.

2. core components are strictly screened, and brand products are selected for superior performance.

3. resistance to impact and corrosion resistance

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.

Use of attention

1. the product is FL10 type interface, which is not suitable for other interfaces.
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, only one antenna can be used without amplifier.
3. the joints of most antennas are N type, so the two connectors of the surge arrester are two N heads. One is the N public (the antenna), and the other is N mother.
