ABSTRACT:
A radiating air-dielectric coaxial cable for plenum applications comprises an inner conductor; a non-halogenated dielectric spacer around the inner conductor; and a single, continuous, outer conductor surrounding the dielectric spacer in direct contact therewith. The outer conductor has apertures along its length for the passage of electromagnetic radiation. At least one layer of inert, flame-retardant barrier tape is wrapped over the outer surface of the outer conductor so as to cover each of the radiating apertures of said outer conductor to prevent the dielectric spacer from flowing out through the radiating apertures when the dielectric material is melted. A jacket of halogenated, highly flame-retardant polymer is extruded over the wrapped layer of barrier tape.
