A quad-shield coaxial cable includes, an elongated center conductor extending along a longitudinal axis, an insulator coaxially surrounding the inner conductor, an inner conductive foil layer coaxially surrounding the insulator, an inner layer of braided shield coaxially surrounding the inner foil layer, an outer layer of braided shield coaxially surrounding the inner layer of braided shield, an outer conductive foil layer coaxially surrounding the outer layer of braided shield, and a jacket coaxially surrounding the outer conductive foil layer.
