A circuit arrangement for distributing an antenna signal to input terminals of two appliances. One of these appliances is connected to a variable frequency modulator. An attenuating filter stage is connected between a pre-amplifier and the input of the appliance that is connected to the modulator. The pre-amplifier receives and amplifies the antenna signal. The attenuating filter stage is a frequency trap which has a trapping frequency that is identical to the modulator frequency and is synchronized with tuning of the modulator frequency. The attenuating filter stage, furthermore, is always exactly tuned to the frequency of the modulator and has a tuned frequency that is always aligned in parallel to the frequency of an oscillator in the modulator, so that modulation is not present.
