Abstract
The present invention is a low cost coaxial drop cable having excellent flexibility and shielding coverage. The shielded coaxial cable of the invention includes an elongate center conductor, a dielectric layer surrounding the center conductor, an electrically conductive shield surrounding the dielectric layer, a first plurality of elongate wires surrounding the electrically conductive shield, and a protective jacket surrounding the plurality of elongate wires. The elongate wires have an elliptical cross section with a major axis to minor axis ratio of from greater than 1:1 to less than 5:1. The present invention further includes a method of making the coaxial cable of the invention.
