Flame Retardant Coaxial Cables
Flame Retardant RG11 Coaxial Cables
Application
The cables are designed for CCTV, security, smoke detection and evacuation monitoring applications, where
continued functionality is required during a fire situation. Due to the zero halogen low smoke construction, this
cable is ideal for use in public, commercial and industrial environments.
Standards
Basic design to MIL-C-17
