- 天盾- Basic description

Antenna-fed switch series lightning arresters are mainly used in RF signal systems to protect communication equipment signal lines from lightning electromagnetic pulses, induced overvoltages, and operating overvoltages. They are widely used in wireless coverage, communication base stations, cable TV, and satellite TV. , GPS and other fields 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.
