Extreme-Flex LMR-240-UF Coaxial Cable
LMR-240-UF UltraFlex coaxial cable is the highly-flexible version of the LMR-240 series, engineered for installations that require repeated bending, tight routing, and continuous movement without sacrificing signal performance. It achieves the low-loss characteristics of traditional semi-rigid cable with the flexibility of a traditional RG cable, making it the superior choice for jumpers, portable systems, and dynamic outdoor applications.
Unlike the solid conductor in standard LMR-240, the stranded conductor allows the cable to flex repeatedly without damage, maintaining a stable electrical path. This rubberized, durable outer jacket offers maximum flexibility, superior abrasion resistance, and excellent weatherability for both indoor and outdoor use.

Ideal Applications
- Jumper Assemblies: Ideal for short, high-flex connections between radio equipment, antennas, and lightning protectors.
- Mobile and Vehicular Antennas: Perfect for installations on vehicles where the cable is subject to constant vibration and movement.
- WLAN/Wi-Fi & IoT: Connecting high-gain antennas for 2.4 GHz and 5 GHz systems where tight routing is necessary.
- Amateur Radio & CB: Excellent for portable setups, field day operations, and short antenna feed runs.
- RF Test Labs: Used as high-quality, durable test leads that can be coiled and uncoiled repeatedly.
- SCADA, GPS, and WISP: Reliable feed lines for fixed and mobile data collection systems.
