1. An interference-protected method for supplying power to a receiver in a cellular radio system, said method being employed at a base station (10) in a cellular radio system, said base station comprising main devices (14), peripheral devices (12), and an antenna line (13) between the main devices (14) and the peripheral devices (12), said main devices (14) comprising at least a power supply (14c) and an antenna filter (14b), and said peripheral devices (12) comprising at least a masthead amplifier, characterized by supplying operational voltage from a main device (14) to a peripheral device (12) of the base station through the antenna line (13),separating the operational voltage supplied on the antenna line (13) and a signal from an antenna (11) from each other in a peripheral device (12) by filtering (12a), andconducting overvoltage formed on the antenna line (13) to the ground (27) through a component (25) which changes its impedance as a function of voltage, and through an impedance matching stub (24) which is connected thereto and operates on the radio frequencies used by the base station (10).
