About This Assembly
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.
Frequently Asked Questions
Is this cable hand-assembled in the USA?
Yes. Every CoaxRF cable assembly is hand-terminated and continuity tested at our US facility before shipping. We do not drop-ship pre-made cables from overseas — each cable is built to order.
Can I order a different length than 100 ft?
Yes. This page is for the 100 ft assembly. Use the length buttons above to select a different standard length, or use the Cable Builder for any custom length.
How much signal loss will I see with this 100 ft cable?
At 1800 MHz, RFC400 loses approximately 6.8 dB per 100 ft. This 100 ft assembly will have roughly 6.8 dB of insertion loss at that frequency. See the signal loss table for all frequency points.
What is the maximum frequency for this assembly?
This assembly is rated DC – 6 GHz. The effective frequency limit is set by the lowest-rated component — either the cable or one of the connectors. Both N FEMALE and N MALE connectors must be within spec at your target frequency.
What is your return policy?
We accept returns within 30 days of delivery. Custom-length cables are accepted as long as they are in original condition. Contact us and we will provide a prepaid return label at no charge.
