Abstract

Abstract A coaxial cable is disclosed that employs a plain stitch wire tube formed by braiding a plurality of flattened individual solid metal conductors. The plain stitch wire tube obtained by braiding the flattened conducting wires acts as an external conductor. The coaxial cable may be used, for example, as a feeder cable for an automobile antenna. The coaxial cable thus obtained provides improved shielding against inductive interference and can be manufactured at a lower cost compared with conventional cables.
