RF Surge Protectors

RF surge protectors safeguard your coax runs and RF kit from high-voltage transients by diverting surge energy safely to ground. They’re a must on towers, rooftops or any site exposed to lightning or switching spikes. When choosing, match the protector’s frequency range and connector style to your system, then check insertion loss (ideally under 0.5 dB) and VSWR. Power handling should exceed your transmitter output, and surge ratings (peak voltage and discharge current) must suit local lightning risk. Consider single-line versus multi-line units, DC-pass requirements, and whether you need indoor or weatherproof outdoor mounting. The right protector preserves signal integrity while channeling harmful transients away from sensitive receivers and transmitters.
