Used For
N-Type Low-Loss Feedline — RFC400
Connects N-type outdoor antennas, panel arrays, and base station antenna ports to transceivers, amplifiers, and RF distribution equipment. RFC400 delivers 2.5 dB/100ft at 1 GHz — the cost-effective choice for medium and long antenna feedlines where cable length would otherwise degrade system performance.

About This Assembly
Specs Summary
RFC400 Cable
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.
N Connector
Type N is a threaded RF connector rated from DC to 18 GHz with a durable weatherproof design, making it the preferred interface for outdoor antenna installations, cellular base stations, and commercial wireless infrastructure. Its larger size compared to SMA allows higher power handling and the threaded coupling resists vibration, making it suitable for mobile and fixed outdoor applications.
Common Applications
This N cable assembly is well suited for cost-effective long antenna runs, cellular repeater trunk cables, and outdoor feedlines. The combination of reliable N connectors and custom-cut cable length makes it a practical choice for both field installations and bench setups. Every assembly is hand-terminated, continuity tested, and ships free within the USA.
