Electrical Equipment & Systems

Coaxial Lightning Arrestors operate from 2 MHz to 2 GHz.

Equipped with TNC to SMA connectors, SurgeGuard™ PTI-TNF-SAF Series provides 2-stage protection. First stage consists of Gas Discharge Tube to shunt high voltages to grounded outer conductor/shield, while second stage uses series capacitor on line, which reduces amount of energy that continues into radio front end. With nickel-over-brass construction and gold-plated center conductor, waterproof...
