Abstract
A radiating coaxial high-frequency cable is provided with openings in the outer conductor which are in the form of slots (,) arranged substantially perpendicular to the cable axis. The slots (,) are arranged in sections which are arranged consecutively without gaps in the longitudinal direction of the cable and whose axial length is dimensioned according to the high-frequency energy to be transmitted. The number of slots (,) is greater in the sections which are farther away from the feed location of the high-frequency energy than in the sections which are closer to the feed location. When the length of the cable is increased, several sections (A) with an identical number of slots are arranged consecutively without gaps, provided that subsequent sections (A) have a larger effectual opening when the system damping between the high-frequency cable and an antenna located outside the cable reaches a predetermined value.
