A radiating cable of the foam dielectric type is provided with increased flame-retardant capabilities by provision of an inert barrier tape (5) between an apertured, corrugated outer conductor (3) and the external jacket (6) surrounding the conductor (5). The barrier tape (5) is composed of non-halogenated, self-extinguishing insulating material and is wrapped over the outer conductor (3) in such a way as to completely cover the radiating apertures (4) disposed thereupon. The barrier tape (5) prevents the melting and bubbling of the dielectric foam (2) outwardly through the radiating slots (4) into penetrating contact with the external jacket (6) when the cable is subjected to high-intensity flames, without significantly affecting the transmission characteristics of the cable. |
