Abstract
A system for connecting at least two receivers to a common antenna is proposed, antenna signal lines being supplied to the receivers, which stands out in that the input impedances of the at least two receivers are matched only in a narrow-band fashion in the range of their current reception frequencies to the impedances of the antenna signal lines supplied to them. An antenna signal splitter is also proposed. Finally, a method for controlling the reception frequencies of at least two receivers connected to a common receiving antenna is proposed, which is distinguished by the fact that the reception frequencies of the at least two receivers are set in such a way that they maintain a predefined minimum frequency distance from one another. A reduction of an antenna signal attenuation in an antenna signal splitter for multiple receiver systems is thereby possible, provided the receivers are tuned to different reception frequencies.
