Abstract (en)
[origin: WO03028247A1] An improved antenna diversity receiving system comprising an antenna device including a plurality of FM antennas (5), as well as controllable switching means (33) for sequentially siwthcing through one of said plutality of FM antennas (5) via an antenna cable (9) to a radio set (3) comprising a mulitpath detector (15) coupled to a pulse generator (19) for generating a pulse signal at the detection pultipath detector of multipath interference, a pulse signal to the pulse generator into a pulse signalvomprises the additional features: there is a pilot signal generator (45); the pilot signal generator (45) provides a signal depending on AM/FM switching, there is an additional pilot signal detection witch control (41) controlled directly or indirectly by the pilot signal generator (45) via the cable (9); and via the pilot signal detection and witch control (41) the AM branch in the antenna diversity box will be activated or inactivated or an AM antenna signal will be amplified and/or switched off.
