SYMAIR Feeder Connectors are field-installable RF connectors designed for on-site termination of corrugated coaxial feeder cables. Unlike factory-terminated assemblies, they allow installation teams to cut cables to the exact required length on-site, connect directly to any port, and complete termination without specialist factory equipment. SYMAIR's feeder connector lineup covers cable sizes from 1/2" through 1-5/8", and supports three major interface standards - 4.3-10, 7/16 DIN, and N-type - making them compatible with the full range of SYMAIR foam and superflexible coaxial feeder cables.
