1 Scope
This document specifies the required characteristics of coaxial cables, 50 Ω, type WN, for use in aircraft
electrical systems at operating temperatures between −55 °C and 200 °C and specially for high
frequency up to 6 GHz.
The document encloses also a reinforced cable version (code R) which is used for sensitive systems
with controlled VSWR.
