A diversity aerial system for a moving vehicle with at least two diversity aerials and with a heating field arranged in the region of a disc, with conductor elements (collector rails) at the front end in order to supply the heating current and with conductor elements to be heated arranged between these elements. This system is so designed that each diversity aerial is provided with such front-end mounted conductor elements (4a, 4d; 4b, 4c), and between these, conductor elements to be heated (2a, 2b) and a clamping pair which is connected with a continuing network (8a, 8b) of the diversity aerial; that each clamping pair has an earth connection point (14a, 14b) and a conductor element connection point (5a, 5b); that the conductor element connection points (5a, 5b) of all diversity aerials are arranged in such a way that they are essentially HF de-coupled from one another; and that HF power blocking elements (6a-d) are provided in the heating current supply lines. In this way, the average reception quality is as good as possible with each individual aerial and the amount of interference occurring simultaneously in the signals is minimum. |
