Abstract
A multi-shielded transmission cable has no "slots" in the shielding so that signal attenuation and distortion are minimized. A shielding tape for the ready manufacture of the cable has at least one conducting layer and an insulating layer and is folded at or near its longitudinal median. When the tape is wrapped about a cable core, the ends of the tape overlap so as to effect physical and electrical contact thereby avoiding slots. A heat-sensitive adhesive strip may be applied to the tape so that the shielding is bonded to the core during the step of extruding a protective jacket over the shielding tape.
