About This Assembly

RFC240 Cable

RFC-240 is a 0.240" 50-ohm low-loss coaxial cable delivering performance comparable to LMR-240 at a more accessible price, making it popular for installers who need reliable medium-distance cable runs. Well suited for cellular repeater installations, point-to-point wireless links, and access point feedlines up to 75 feet.

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.

RP-TNC Connector

RP-TNC (Reverse Polarity TNC) uses the TNC threaded shell with reversed pin conventions, similar to RP-SMA. It is used on some commercial WiFi access points and outdoor CPE antennas, particularly in older Cisco and Linksys equipment, and offers better vibration resistance than RP-SMA in demanding outdoor environments.

Common Applications

This RP-SMA and RP-TNC cable assembly is well suited for medium-length cellular and WiFi antenna runs at a value price point. The combination of reliable RP-SMA and RP-TNC 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.
