摘要： An arrangement for connecting at least two receivers to a common antenna is disclosed, whereby antenna signal lines are fed to the receivers, is characterised in that the input impedances for the at least two receivers are only matched to the impedance of the supplied antenna signal lines in the narrow band of the region of the current receiver frequencies. An antenna signal splitter is further disclosed and also a method for control of the receiver frequencies of at least two receivers, connected to a common receiver antenna, which is characterised in that the receiver frequencies for the at least two receivers are set such that they have a pre-determined minimum frequency difference from each other. The invention permits a reduction in an antenna signal damping in an antenna signal splitter for multi-receiver systems so long as the receivers are matched to differing receiver frequencies.
