About RFC400
RFC-400 is a cost-effective 0.400" 50-ohm low-loss coaxial cable serving as a value-oriented alternative to LMR-400. It delivers strong performance on runs from 50 to 200 feet and is popular for cellular repeater trunk cables, outdoor antenna feedlines, and budget-conscious infrastructure deployments.

What is the impedance of RFC400?
50 Ohm — standard for RF systems, test equipment, and antenna feedlines.
What frequency range does RFC400 support?
RFC400 supports frequencies from DC to DC – 6 GHz.
How are RFC400 cables assembled?
Every RFC400 cable assembly is hand-terminated and continuity tested at our US facility before shipping. We do not drop-ship pre-made cables — each one is built to your specifications.
What lengths are available for RFC400?
RFC400 is available from 1 ft up to 1200 ft. Use the cable builder for any custom length.
