Abstract (en)
[origin: DE19935675A1] This invention relates to a circuit for switching between frequency modulated HF signals of at least two receiver antennas (8, 9, 10, 11) and a control unit (6, 7) which switches according to the quality of the output signals of the said antennas between individual antennas. The invention is characterized by a detector (19) which sends a signal to the control unit thereby effecting switching to a given antenna when none of the antennas supplies a signal exceeding a predetermined minimum reception level.
