Abstract
A flexible coaxial cable comprises a core including at least one inner conductor and a closed cell foam dielectric surrounding the inner conductor. The flexible coaxial cable also includes a tubular metallic sheath closely surrounding and preferably bonded to the core. The closed cell foam dielectric is a low density polyolefin foam and possesses improved electrical properties over conventional foam dielectrics. The coaxial cable has a velocity of propagation of greater than 90 percent of the speed of light but still maintains high flexibility and bending characteristics.
