Abstract
A coaxial communications cable has a center conductor extending coaxially of the longitudinal axis of the cable with a low loss foam dielectric surrounding the inner conductor and bonded thereto. An electrically and mechanically continuous sheath surrounds the foam dielectric. The sheath is a smooth-walled longitudinally welded tube formed of a bimetallic material, which in one embodiment has an inwardly facing copper layer and an outwardly facing aluminum layer. A polymeric jacket surrounds the tubular sheath and is bonded thereto.
