1. A coaxial cable comprising:
- an inner conductor, an outer conductor and a dielectric material layer therebetween;
said inner conductor comprising a tubular bimetallic layer and having a pair of opposing longitudinal edge portions at a longitudinal seam;
said tubular bimetallic layer comprising an inner metal layer and an outer metal layer bonded thereto and coextensive therewith;
said opposing longitudinal edge portions being angled inwardly to define a pair of adjacent inwardly extending tabs that include both said inner metal layer and said outer metal layer.

Abstract
A coaxial cable may include an inner conductor, an outer conductor and a dielectric material layer therebetween. The inner conductor may include a tubular bimetallic layer and may have a pair of opposing longitudinal edge portions at a longitudinal seam. The tubular bimetallic layer may include an inner metal layer and an outer metal layer bonded thereto and coextensive therewith. In addition, the opposing longitudinal edge portions may be angled inwardly to define a pair of adjacent inwardly extending tabs.
