Abstract
In an arrangement for the transmission of radio frequency signals between a radio frequency line emitting waves and a mobile antenna, the radio frequency line having an inner conductor (1), a coaxial outer conductor (2) and a dielectric (3), and openings being provided in the outer conductor of the radio frequency line for the emission or reception of waves, it is provided that different types of groups of openings (4, 5) are located in the longitudinal direction of the radio frequency line, on different sleeve lines, and that the individual opening in the longitudinal direction of the radio frequency line in the case of one group of openings is at least twice as long as in the case of another group. <IMAGE>
