<p>A shielding tape particularly designed for CATV cable in which a single conductor is surrounded by insulation which is in turn wrapped by the tape comprises a laminate base tape of a conducting foil and a non-conducting plastic film. The base tape is folded along two fold lines spaced by slightly less than half the width of the base tape with the foil outermost at each of the folds and the edges of the base tape overlapping. A bonding layer can be applied on the side of the folded tape with the overlapping edges. An additional narrow J-fold can be applied along one edge to provide additional contact between the foil at the overlap. The continuous extent of the foil around the full periphery of the tape provides an improved "slot free" shielding effect.</p> |
