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.

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.

Common Applications

This RP-SMA and SMA cable assembly is well suited for flexible outdoor antenna runs and budget-conscious mobile installations. The combination of reliable RP-SMA and SMA 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.
