Receivers (1) comprising television and radio inputs (11,12) for receiving television and radio signals and comprising switching circuits (2) with two first switches (21,22) to be activated in a first mode and located parallelly to the television input (11) and with two second switches (23,24) to be activated in a second mode and located anti-serially to the radio input (12), and control circuits (3) for controlling the switching circuits (2) are modified in such a way that strong radio signals can no longer disturb the television signals. Thereby one of the first switches (21) and one of the second switches (23) together isolate the inputs (11,12) from each other, and the control circuit (3) supplies a first control signal to the first switches (21,22) and supplies a second control signal to non-common points of the anti-serial second switches (23,24). This kind of receivers (1) no longer need different switching circuits (2) for shielded radio inputs and unshielded radio inputs. be switches (21,22,23,24) are diodes, and the control circuit (3) comprises transistors (31,32) for controlling the diodes.
