About This Assembly

RFC400 ULTRA FLEX Cable

RFC-400-UltraFlex combines the low-loss performance of 0.400" coax with the flexibility needed for complex routing, offering an economical option for installations that benefit from increased bendability. Suitable for rooftop antenna runs, equipment room patch cables, and mobile installs where budget and flexibility are both priorities.

BNC Connector

BNC (Bayonet Neill–Concelman) is a quick-connect RF connector featuring a bayonet locking mechanism for fast mating and unmating, rated from DC to 4 GHz. Its ease of use makes it standard in test and measurement equipment, video distribution, two-way radio accessories, and laboratory bench setups where cables are frequently connected and disconnected.

Common Applications

This BNC cable assembly is well suited for flexible outdoor antenna runs and budget-conscious mobile installations. The combination of reliable BNC 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 6 ft?

Yes. This page is for the 6 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 6 ft cable?

At 1800 MHz, RFC400 ULTRA FLEX loses approximately 7.2 dB per 100 ft. This 6 ft assembly will have roughly 0.43 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 – 4 GHz. The effective frequency limit is set by the lowest-rated component — either the cable or one of the connectors. Both BNC MALE and BNC 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.
