Type N-Male to SO-239 (UHF-Female) Coax Adapter
Type N-Male to SO-239 (UHF-Female) Coax Adapter

Description
Connect your standard PL-259 coax cables to high-performance gear with this heavy-duty adapter. It converts a Type N-Female port (common on repeaters, diplexers, and high-end base station antennas) into a standard SO-239 (UHF-Female) socket.
This is the essential "bridge" adapter for ham radio operators who use commercial-grade antennas or equipment but want to use their existing standard RG58 or RG213 coaxial cables.
