Significantly reduce your radio-frequency cable weight with our lightweight, high-performance, 50- and 75-ohm coaxial and triaxial cables. We offer two types: polyethylene (PFLX) and fluorinated ethylene propylene (TFLX). These high-temperature coaxial and triaxial cables exceed FAA flammability testing requirements. Available in bulk or as prefabricated and certified cable assemblies, contact us to find the right cable solution for your aircraft.

PFLX and TFLX cables
Both cables are approved by the Federal Aviation Administration (FAA) and original equipment manufacturers. Though suited for different needs, they’re as much as 75 percent lighter than many radio guide (RG) and MIL-C-17 cables – while delivering superior electrical performance.
PFLX: Resistant to kinking and hydraulic fluids, these cables offer excellent shielding effectiveness and flexibility with low smoke and zero halogen at high temperatures
