1. A cable comprising:

  • an inner conductor extending along an elongate axis;

    an insulator receiving the inner conductor and extending along the elongate axis;

    an outer conductor receiving the insulator and extending along the elongate axis;

    a separating foil disposed between the insulator and the outer conductor, the separating foil facilitating separation and insertion of a post sleeve of a coaxial cable connector;

    an insulating jacket receiving the outer conductor and extending along the elongate axis, the insulating jacket configured to electrically insulate the inner and outer conductors from an electrical ground;

    a structurally reinforcing jacket disposed over the insulating jacket and extending along the elongate axis, the structurally reinforcing jacket configured to structurally augment and puncture-protect the cable axially along the elongate axis; and

    a separating material interposing the insulating and structurally reinforcing jackets, the separating material facilitating separation and insertion of a retention post,wherein the structurally reinforcing jacket including reinforcing fibers disposed in a binding matrix material, the binding matrix having inner and outer portions, the outer portion including a radius dimension greater than one half of the total radius dimension,wherein the fibers reinforce the outer portion of the reinforcing jacket;

    wherein the reinforcing fibers comprise fibers having high yield strength and low elastic modulus material properties, and a combination of on-axis and off-axis fibers, the on-axis fibers oriented at less than about twenty five degrees (+/−

    25°

    ) relative to the elongate axis and the off-axis fibers oriented at greater than about thirty-five degrees (+/−

    35°

    ) relative to the elongate axis;

    wherein the reinforcing fibers are selected from the group consisting of carbon, graphite, boron, fiberglass and polyparaphenylene terephthalamide fibers; and

    wherein the binding matrix material comprising a non-conductive, low modulus material from the group of elastomer, polyethylene and polyurethane.
