Aircraft Coaxial & Triaxial Cables - 50 Ohm PIC 50-ohm coaxial and triaxial cables are lightweight, flexible, low loss, high-temperature, high-tech cables designed specifically for aircraft systems and other harsh environments. Most are constructed with silver-plated copper conductors and shielding. Most 50-ohm designs also incorporate extra shielding for superior EMI protection. PIC aircraft cables and aircraft cable assemblies are widely specified for major avionic systems in commercial, corporate and military aircraft and all of them meet or exceed FAA flammability requirements. A test report is included with every assembly.
