ABSTRACT:
A leaky coaxial cable is disclosed having an axial conductor, a dielectric layer coaxial along the length of the conductor and an outer conductive shield coaxial with the dielectric layer. The outer shield comprises a nonconductive elongate film carrier having a pair of spaced electrically conductive foil strips formed thereon which define a uniform width gap therebetween along the length of the film, the film being disposed about the circumference of the dielectric layer such that outer lateral edges of the foil strips overlap and the uniform width gap extends along the length of the cable. The film carrier may be applied on the dielectric layer either longitudinally thereof or by helically winding the film along the length of the dielectric layer. The cable also preferably includes at least one drain wire and an outer protective jacket.
