Abstract

In order to prevent the generation of interfering signals, e.g. in adjacent frequency ranges, in a VHF radio transmission installation with at least two transmitters connected via a transmitter filter to a common antenna, the input of the power amplifier of one transmitter is supplied with part of the output power of the control amplifier of at least one of the other transmitters in such a way as to compensate for the interference power of the other transmitter.
