  • Patent number: 6058297
    Abstract: A vehicle mounted radio receiver comprising a diversity control circuit for detection of multi-path via two or more antennas (14,15). An antenna selector unit (13) is also arranged for selection of the strongest antenna signal. The antenna selector unit (13) is connected to a detecting circuit (18-21) comprising means for automatic locking of the antenna selector unit to a main antenna (14) when detecting interrupted function at a sub-antenna (15). The automatic locking to the main antenna of the vehicle is accomplished, either in that the detecting circuit for antenna function comprises an antenna signal amplifier which is connected to the sub-antenna (15) and to a source of power, or in that the detecting circuit for antenna function comprises a load circuit which is connected to the sub-antenna (15) and to a source of power.
