Specs Summary
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.
SMA Connector
SMA (SubMiniature version A) is the most widely used RF connector in the industry, offering a threaded interface that provides a secure, low-reflection connection from DC to 18 GHz. Its compact size, 50-ohm impedance, and broad frequency range make it the default choice for WiFi equipment, software-defined radios, cellular antennas, GPS receivers, and RF test instruments.
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 SMA and UHF cable assembly is well suited for mobile radio installs, rooftop antenna runs, and rack-mounted equipment. The combination of reliable SMA 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
What is LMR400 ULTRA FLEX Times coaxial cable used for?
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.
What is the signal loss of LMR400 ULTRA FLEX Times?
At 1800 MHz, LMR400 ULTRA FLEX Times has approximately 7.2 dB of loss per 100 ft (0.072 dB/ft).
What frequency range does this assembly support?
This assembly is rated DC – 300 MHz, limited by the lowest-rated component across the cable and connectors.
What is a SMA connector?
SMA (SubMiniature version A) is the most widely used RF connector in the industry, offering a threaded interface that provides a secure, low-reflection connection from DC to 18 GHz. Its compact size, 50-ohm impedance, and broad frequency range make it the default choice for WiFi equipment, software-defined radios, cellular antennas, GPS receivers, and RF test instruments.
