Foam insulated radio frequency cables
Radio-frequency cable RK 50-7,2-a90P
Application
Radio-frequency coaxial cables are designed for a single stationary installation in the antenna paths of radio communication systems, in television and radio broadcasting systems. The design is similar to cables of the type RG-8 / U, LMR-400, 8D-FB. Cables can be used with BNC, TNC and N connectors. Operated outdoors.
