Abstract:
A coaxial drop cable having predetermined signal transmission characteristics, including enhanced shielding properties, for transmitting both communications signals and electrical power, wherein the coaxial drop cable is adapted to extend between a distribution cable of a communications system and receiver means associated with at least one subscriber of the communications system, the coaxial drop cable comprising:an elongate center conductor;a dielectric material surrounding said center conductor;an adhesive layer disposed between said center conductor and said dielectric material for bonding said dielectric layer to said center conductor; andan annular outer conductor surrounding said dielectric material and being adhesively bonded thereto to form an integral cable core, said outer conductor comprised of a mechanically and electrically continuous, non-overlapping, tubular metallic shield,wherein said dielectric material has a predetermined density of at least 0.30 g/cm.sup.3 and a corresponding predetermined compressive stiffness of at least 1000 pounds per linear inch, and wherein said outer conductor has a predetermined thickness which is at least 2.5% of its outer diameter such that the coaxial drop cable can efficiently transmit electrical power and can be readily flexed while maintaining the predetermined signal transmission characteristics.
