Coaxial cable and method for forming the cable
A cable may include a include an inner conductor and an outer conductor coaxially arranged around the inner conductor. A dielectric strength member may be positioned between the inner and outer conductors. The dielectric strength member may have a tensile strength of at least 10,000 MPa. Additionally, a jacket may be formed around the outer conductor.
