Abstract
A coaxial cable includes an inner conductor, a multifilament twisted and drawn or swaged tubular cable outer conductor, and a dielectric (insulative) material therebetween. According to one embodiment, the filaments of the multifilament twisted and drawn or swaged outer conductor are twisted about a central inner conductor provided with an insulative sheath. The outer conductor filaments are arranged such that when they are drawn or swaged, the compressive forces are directed on neighboring filaments and not directed radially inward toward the inner conductor, thereby preventing deformation of the inner conductor. According to another embodiment, each of the filaments is provided with an insulative sheath. According to other embodiments, a cable is formed with a central filament harder than the surrounding filaments. The central filament is withdrawn leaving behind a twisted and drawn or swaged tube with a hollow.
