Feature: 1. Comprehensive Protection: Absorbs and grounds lightning surges from antennas on top of buildings, providing complete protection for transceivers, receivers, etc. 2. Safety Guarantee: Designed with high safety in mind, the built in inflatable lightning arrester element discharges and grounds the surge when the surge voltage exceeds a specified level. 3. Convenient and Practical: Surge discharge and recovery action can be repeated as needed. If the lightning arrester components are damaged, they can be easily replaced with new components. 4. Superior Performance: The coaxial structure of the lightning surge protector ensures excellent high frequency characteristics, wide bandwidth, low loss and VSWR. 5. Easy Installation: The coaxial lightning surge arrester adopts 1/4 wavelength short circuit principle, good lightning protection. Simple structure, sturdy and easy to install.
