Abstract
A high frequency coaxial cable (1) contains a concentric internal conductor (3), a cylindrical insulating layer (7) surrounding the internal conductor (3) and made of a foamed plastic containing more than 50% by volume of air, a tubular external conductor (9) placed over the insulating layer (7), and an outer sheath (11). Cutouts (15, 15') are made in the insulating layer (7) by removing insulation material starting at the periphery (13) of the insulating layer and extending radially inward. These cutouts (15, 15') make it possible to increase the dielectric properties of the insulating layer between internal conductor (3) and external conductor (9).
