Coaxial RF Protection

RF coaxial lightning surge protectors (lightning arrestors/suppressors) product line consists of passive microwave components that protect against high electromagnetic pulses (EMP) or extreme power surges, typically caused by lightning strikes.

RF coaxial lightning surge protectors from Polyphaser are commonly used on antenna installations to protect sensitive equipment and are specially designed to pass the desired frequency while suppressing lightning surges.

These radio frequency coaxial lightning surge protection products have hybrid & replaceable gas discharge capsule and a ground lug terminal to provide superior grounding.
