JEFA Tech Low Loss 400 Flex is a high performance alternative to Times Microwave Systems® LMR-400UF and Belden 9913F7 flexible coax cable. Low Loss 400 Flex is recommended for applications where the coax cable will be in motion, for example, beam antennas that are on a rotator, or patch cables to go from your patch panel to radio equipment. The stranded center conductor and flexible jacket allow the cable to flex easily. Continuous flexing will not compromise the integrity of the cable.

Our coax cable is produced to strict tolerances and stored in our climate controlled warehouse in the state of Maryland, USA.

JEFA Tech has been in business since 2003. We are well established and here to stay and support you with a quality product.

We stand behind the quality and performance of the cable and offer a 30 day money back guarantee and five year warranty.

Trusted by many military and government customers including the HAARP (High Frequency Active Auroral Research Program) in Alaska.

Note that you are trading a small amount of performance to gain flexibility. For maximum performance in a permanent (non moving) installation, standard Low Loss 400 (LL400) with the solid center conductor is recommended. For installations that will have the cable in motion such as around a rotor, Low Loss 400 FLEX is recommended.

Are you an amateur radio operator? This cable is the same size as RG-8 and RG-213 and will accept the same connectors! Standard PL-259 connectors fit with no adapters needed. Upgrade your shack to this higher quality, much lower loss cable today! It will dramatically reduce your signal loss on VHF and UHF. It will increase your receive signal and handle more power on HF. JEFA Tech coax is used by many fine ham radio operators world wide and is even used by the experimental HAARP (High Frequency Active Auroral Research Program) in Alaska.
