Abstract
The present invention provides diversity reception to effectively compensate for signal reception fading without using separate antenna structures and while using the heating element antenna of an electrically heated window of a motor vehicle. Such is accomplished by providing common (unbalanced) and balanced signal separation configurations and signal selection circuitry between the heating element antenna and the VHF aerial input terminal of a vehicle radio receiver, wherein the signal selection circuitry selectively connects the signal outputs of the common and balanced signal separation configurations to the VHF aerial input in dependence on monitored characteristics of the radio signals produced at these outputs and received by the vehicle radio receiver.
