Data Sheet: GORE® Coaxial Cable - Optimized RG400

United States

Data Sheet for GORE® Optimized RG400 Coaxial Cable; includes description, features, benefits, and technical specifications.


Summary

GORE Optimized RG400 Coaxial Cable is designed to be a direct replacement for RG400 cable. Gore’s cable is 60% lighter weight and 30% smaller diameter compared to standard RG400 cable. The cable is suitable for use in commercial and military aircraft and is an ideal choice for aircraft electronics retrofits because it is small, flexible, and easy to route. Typical applications include navigation, communications, box-to-antenna, and in-flight entertainment.

Technical Specifications

GORE Optimized RG400 Coaxial Cable meets the stringent requirements of both EN 4604-003 and FAR25.853. The 50 ohm cable meets and exceeds the electrical requirements of MIL-C-17. Designed for use in aircraft electrical systems, the cable has an operating temperature range of -65°C to +200°C. The maximum operating frequency is greater than 3 GHz and the outer jacket of the cable is UV-laser printable.

A special cable design provides enhanced performance allowing GORE Optimized RG400 Coaxial Cable to have 10% lower attenuation. Environmental protection is achieved with the use of a FEP outer jacket.

GORE Optimized RG400 Coaxial Cable offers significant weight savings. If the GORE™ Cable replaced all of the standard RG400 cable on a typical large cabin business jet, expectations of weight savings is approximately 42 lbs (19kg). When GORE Optimized RG400 Coaxial Cable replaced standard RG400 cable on the Airbus 330/340 in-flight entertainment system, the weight savings was 48 lbs (22 kg) from that one application.
