BRAID CONFIGURATIONS IN COAXIAL CABLES
Braid configurations in coaxial cables. In one example embodiment, a coaxial cable includes a center conductor surrounded by a dielectric, a first braid surrounding the dielectric, a second braid surrounding and adjacent to the first braid, and a jacket surrounding the second braid. The first braid is formed from a first material that is a conductive material. The second braid is formed from a second material that is more compressible and/or has a lower frictional coefficient than the first material.
