Abstract
Disclosed are several embodiments of Improved CATV (Coaxial Drop Wire), using either foil laminate or a metallic braid in combination with another foil laminate adhesively bonded to the drop wire core dielectric, the improvements being (a) the elimination of traverse (radial) cracks, commonly called 'tiger striping,' developing in the foil as a result of the foil wrinkling, and (b) the elimination of slot antenna effect. One embodiment employs two laminated tapes, one circumferentially surrounding the other and both circumferentially surrounding a core. One laminated tape is bonded to the core dielectric and the other is bonded to a jacket, surrounding the outer laminate tape. The other embodiment employs a metallic braid tape circumferentially surrounding a metal foil-plastic film-metal foil laminate tape adhesively bonded to the core dielectric. Added strength is imparted to the Drop Wire by means of a tape made from woven strands of glass, bonded to the innermost surface of the plastic jacket circumferentially surrounding the outer conductor (braid or foil laminate) of each embodiment.
