Specs Summary
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.
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 flexible outdoor antenna runs and budget-conscious mobile installations. 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.
