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.

Frequently Asked Questions

What connectors are compatible with RFC400?

RFC400 is compatible with 15 connector types including SMA MALE, SMA FEMALE, RP-SMA MALE, RP-SMA FEMALE, N MALE, and more. All connectors can be paired in any combination.

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.
