Application No. 08/489,680
that the cable is flexible, the outer conductor includes a
mechanically and electrically continuous, non-overlapping,
tubular metallic shield having an outer diameter of no greater
than 0.40 inches. To remain structurally intact and to resist
cracking or fracturing as the cable is repeatedly flexed,
however, the outer conductor has a thickness of at least 0.006
inches. Accordingly, the outer conductor has a predetermined
thickness that is at least 2.5% of the outer diameter of the
outer conductor.
Claim 9, which is representative for our purposes,
follows:
9. 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;
