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.
- 50 Ohm Low Loss Coax
- Center Conductor - 7 strands of 100% Bare Copper with 0.114" average overall diameter
- Outer Diameter: 0.405" (same as RG-8, RG-213/U, LMR-400, LMR-400UF)
- Jacket: Thermoplastic Elastomer (TPE) Jacket - softer, more flexible than polyethylene - full waterproofing and UV Protection, not direct burial rated
- Shielding: Double Shielded for low loss and interference rejection
- First Shield: Bonded aluminum foil with 100% coverage
- Second Shield: Tinned 100% copper braid with 98% coverage density
- Foam Dielectric - adds to flexibility and performance
- 5 year warranty, 10+ year life expectancy

Note that you are trading a small amount of performance to gain flexibility vs LL400 / LMR-400. 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.
