- 天盾- Basic description

Antenna quarter-wave series lightning arresters are mainly used in radio frequency signal systems to protect communication equipment signal lines from lightning electromagnetic pulses, induced overvoltages, and operating overvoltages. They are widely used in wireless coverage and communication base stations RF line protection. This series of products has the characteristics of wide frequency range, low insertion loss and small standing wave. It has a good lightning protection effect without affecting the normal communication of the equipment.
