About This Assembly
LMR400 ULTRA FLEX Times Cable
LMR-400-UltraFlex delivers the same industry-leading low-loss performance as standard LMR-400 but with a stranded center conductor and more flexible jacket. Practical for mobile platforms, rooftop cellular installs, and dense equipment racks where stiff hardline cable would be difficult to route without damage.
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.
UHF Connector
The UHF connector (also known as PL-259 male / SO-239 female) is a large, low-cost RF connector designed in the 1930s for HF and VHF frequencies. Despite its name, its practical usable range is below 300 MHz due to its non-constant impedance design. It remains extremely popular in amateur radio (HF through VHF), CB radio, and marine radio applications.
Common Applications
This BNC and UHF cable assembly is well suited for mobile radio installs, rooftop antenna runs, and rack-mounted equipment. The combination of reliable BNC and UHF 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 1 ft?
Yes. This page is for the 1 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 1 ft cable?
At 1800 MHz, LMR400 ULTRA FLEX Times loses approximately 7.2 dB per 100 ft. This 1 ft assembly will have roughly 0.07 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 – 300 MHz. The effective frequency limit is set by the lowest-rated component — either the cable or one of the connectors. Both BNC MALE and PL259 UHF 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.
