Abstract
A low distortion cable made of multi-strand conductors including a dielectric core, a plurality of conductive strands of solid cross-section wrapped around the core in a single layer and a plurality of dielectric spacer strands, at least one of which is interspersed between each adjacent one of said conductive strands to form therewith a single layer of alternating conductors and dielectrics about a core. The support for the conductive strands is only at the lines of contact with adjacent strands and the core. A dielectric insulatr surrounds and supports the layer of strands and core in a unitary assembly, the interstices between strands and dielectrics, where not in contact along lines of support, being filled with a dielectric gas, such as air.
