Abstract
The invention is characterized in that a HF coaxial cable is designed as a conventional corrugated sheath cable comprising a cable outer conductor, in the form of a metal corrugated tube, having a line impedance Zk and a minimum bending radius rk,min specified by the manufacturer as a characteristic feature of the coaxial cable; in corrugated sheath cable, directly or indirectly following the straight plug connector, is bent to have a bending radius rα, where 0.2 rk,min≦rα≦0.9 rk,min, which alters the line impedance Zk by a maximum of 1 ohm. The bend with the bending radius rα is produced by cold forming corrugated sheath cable with the introduction of bending forces and tensile forces directed along said corrugated sheath cable.
