CA-35RS Coaxial Lightning Surge Protector Arrester Male to Female UHF Connector Description: The Surge Protector is a lightning arrester of coaxial construction. The device is designed to absorb the surge of lightning strikes on an antenna at the top of a building and ground it, thus providing full lightning protection for transceivers, receivers, etc. Features: Designed with a stress on high safety, this device has a built-in gas-charging surge arrestor element which discharges and grounds the surge at the moment the surge voltage exceeds a specified level. This device makes the actions of surge discharge and restoration as repeatedly as necessary. No replacement is practically needed . Should the surge arrestor element be damaged, it can easily be replaced with a new element. The coaxial construction of this device assures excellent high frequency characteristics, wide bandwidth and low loss and VSWR. 1/4 wavelength short circuit principle for good lightning protection effect. Simple structure, strong, easy installation.
