Coaxial Surge Protection Device

A Coaxial SPD is installed inline with coaxial cables to divert transient surge currents safely to ground without significantly affecting radio frequency (RF) performance. It is commonly used in antenna systems, television distribution, cellular communications, satellite installations, and CCTV systems.

Available with various connector types, these devices are selected based on frequency range, impedance, and connector compatibility.
