About This Assembly

LMR400 Times Cable

LMR-400 is the industry-standard low-loss 50-ohm coaxial cable from Times Microwave with a 0.400" outer diameter, offering less than half the signal loss of RG-8 at 2.4 GHz. The go-to cable for base station feedlines, cellular repeater installations, antenna runs from 50 to 200 feet, and any fixed installation requiring reliable broadband performance.

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 cellular repeater installations, base station feedlines, and long outdoor antenna runs. 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.
