Abstract
A coaxial cable may include an inner conductor, an outer conductor, and a dielectric material layer therebetween. The outer conductor may include a tubular bimetallic layer having a pair of opposing longitudinal edges at a longitudinal seam. The tubular bimetallic layer may include an inner metal layer and an outer metal layer bonded thereto with the outer metal layer having a lower melting point than the inner layer. At least one of the opposing longitudinal edges of the tubular bimetallic layer may be at least partially beveled. In addition, the longitudinal seam may include a welded joint between at least portions of the opposing longitudinal edges.
