Lighter-weight RG coaxial cables for aircraft communication and navigation systems reduce operating costs because they are as much as 20% lighter with a 15% smaller diameter than standard RG cabling. This coaxial cable still meets the electrical and mechanical requirements of MIL-T-81790 and EN 3475-503. The cables are engineered for electrical impedance of 50Ω and 75Ω, and also exceed the electrical requirements of MIL-C-17G.
The special cable design makes routing easy, plus it makes the cable more resistance to abrasion. According to Remo Soave, product engineer, aerospace applications, W. L. Gore & Associates, the unique jacketing material used in the cable’s construction significantly reduces size while maintaining shielding effectiveness, controls impedance, and withstands operating temperatures ranging from -65° C to 150° C.
“Although weight is a crucial factor for the aerospace industry, cable performance cannot be compromised to reduce mass,” noted Soave. “Our experience in developing fluoropolymer-based materials for the rugged environments encountered by aircraft allow us to deliver high-performance, light-weight cables that meet RG specifications.” The lightweight RG coaxial cables suit newly designed systems and retrofit applications because the standard range of RF connectors can be terminated using standard tooling and processes.
