Specs Summary
About This Assembly
LMR240 ULTRA FLEX Times Cable
LMR-240-UltraFlex is the ultra-flexible variant of LMR-240 from Times Microwave, sharing the same electrical performance but with a stranded center conductor and softer jacket that makes it significantly easier to route. Preferred for mobile radio installs, vehicle-mounted antennas, and any application with tight bends or frequent cable movement.
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 vehicle-mounted radio installations, tight-routing applications, and mobile platforms. 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.

Frequently Asked Questions
What is LMR240 ULTRA FLEX Times coaxial cable used for?
LMR-240-UltraFlex is the ultra-flexible variant of LMR-240 from Times Microwave, sharing the same electrical performance but with a stranded center conductor and softer jacket that makes it significantly easier to route. Preferred for mobile radio installs, vehicle-mounted antennas, and any application with tight bends or frequent cable movement.
What is the signal loss of LMR240 ULTRA FLEX Times?
At 1800 MHz, LMR240 ULTRA FLEX Times has approximately 11.2 dB of loss per 100 ft (0.112 dB/ft).
What frequency range does this assembly support?
This assembly is rated DC – 6 GHz, limited by the lowest-rated component across the cable and connectors.
What is a 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.
