RFS's 1/2-inch RADIAFLEX® RCF cable with black jacket. This cable functions as a distributed antenna to provide communications in tunnels, mines and large building complexes and is the solution for any application in confined areas.

Slots in the copper outer conductor allow a controlled portion of the internal RF energy to be radiated into the surrounding environment. Conversely, a signal transmitted near the cable will couple into the slots and be carried along the cable length.

It has a corrugated copper tube outer and copper clad aluminum wire inner conductor along with a halogen free, non corrosive, flame retardant, low smoke, and polyolefin jacket.
