Easy to Install: 1/4 wavelength short circuit principle for good lightning protection effect. Simple structure, strong, easy installation. If you are not completely satisfied with the coaxial lightning protector, please do not hesitate to contact us in time, and we will solve the problem for you as soon as possible. Good Performance: The coaxial construction of this lightning surge protector assures excellent frequency characteristics, wide bandwidth and low loss and VSWR. The lightning arrestor is vailable with several coaxial connection schemes and with multiple RF power ratings. Safety and Security: The lightning arrestor is 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. Repeated Surge Discharge and Recovery: The lightning arrestor 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. Full Lightning Protection:The lightning surge protector adopts 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.
