Product Overview

SC Series RF Connector

Our SC Series RF connector is a robust, threaded coaxial connector designed for demanding medium to high-power applications. It offers environmental resilience and secure connectivity, making it ideal for harsh conditions. With a reliable threaded coupling mechanism, SC connectors provide high mechanical stability and excellent weatherproofing, operating in UHF and lower microwave frequency bands up to 10 GHz. They are widely used in broadcast, military, radar, and industrial RF systems where reliability and superior power handling are crucial.
