High Frequency Coaxial Cable Surge Protect N Interface Good Shielding Effect

High frequency coaxial protection device N interface type lightning arrester coaxial lightning arrester outdoor antenna

Brief introduction

   The N interface lightning protector is a design of lightning protection applied to the antenna feeder system based on the relevant standards. Between the communication equipment and the coaxial cable joint or the two communication equipment, it can effectively prevent the damage of the transient overvoltage formed by the lightning induction to the communication equipment. It is an ideal protection device for all kinds of communication equipment with beautiful appearance, easy installation, easy maintenance, impact resistance and corrosion resistance, and can work steadily in a bad environment for a long time.

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. 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.

  2 .The side of the  lightning arrester has a earthing screw ring, which can be inserted in a thick copper wire and pressed hard and pressed with the tigers forceps. Then the other end of the copper wire is connected to the roof of the building. The contact must be sufficient.

  3. lightning arrester should be connected to the feeder line and installed near the protected equipment.

  4.The N type interface is not applicable to the external interface
