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.

RP-SMA Connector

RP-SMA (Reverse Polarity SMA) uses the SMA threaded coupling mechanism but with the male/female pin convention reversed — the jack has a pin and the plug has a socket. Originally standardized to prevent connection of uncertified antennas to consumer WiFi equipment, RP-SMA is now the dominant connector on commercial WiFi routers, access points, and 2.4/5 GHz antennas.

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 RP-SMA and UHF cable assembly is well suited for mobile radio installs, rooftop antenna runs, and rack-mounted equipment. The combination of reliable RP-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.
