APPLICATION NOTE This cable, featuring a solid center conductor, is a perfect alternative to semi-rigid cable RG402 (dia .141) when flexibility is required. Main benefits: - ultra-low loss - high screening effectiveness - standard connectors for semi-rigid cables can be used - no 3D drawing required for design and manufacturing - high chemical resistance (oil, lubricant, humidity...)
JAR25/FAR25 853 No
