A high frequency coaxial cable suitable for aerial and ultra-high-frequency lines of the type having a metal internal conductor, a plastic dielectric concentrically surrounding the internal conductor, an external conductor surrounding the dielectric and comprising a metal wire mesh and a plastic foil strip metallized on at least one side, and a plastic sheath enveloping the external conductor as an external protective cover, wherein the wires of the wire mesh are arranged in net-like configuration to define an open wire mesh enclosing the dielectric and the plastic foil strip is applied on the wire mesh in helical edgewise overlapping windings with its metallized side facing the wire mesh and is pressed into each single mesh opening of the wire mesh in form of a generally trough-like dent or dimple thereby short-circuiting each single mesh opening of the wire mesh. The plastic foil strip is preferably pressed into the wire mesh opening during the application of the plastic sheath by extruding the latter under high pressure.
