The invention concerns a coaxial resonator construction which makes possible the implementation of a low high-frequency filter which is carried out by coaxial resonators. The adjustment device for the resonator's frequency and the connection adjustment device consist of projections. The adjustment device for the frequency adjusts the connection of the open end of the resonator to the outer or intermediate wall of the filter construction and the connection adjustment device adjusts the connection of the open end of the resonator to the filter construction's other resonator or to the filter construction's input or output. The adjustment devices consist advantageously of plate-shaped projections. The adjustment devices operate at the same time as capacitive loads, in which the physical length of the resonator can be shortened in relation to a non-loaded resonator. The adjustment devices for frequency and connection are most advantageously constructed as projections on one plate-shaped component, in which the resonator according to the invention is constructed of two parts: the resonator and a capacitive load connected to this which at the same time acts as adjustment device for the connection and the frequency. In such a resonator construction, the adjustment of the frequency of the resonator is combined with the adjustment of the connection between the resonator circuits by the use of only one mechanical part so that the adjustments are electrically and mechanically almost independent of each other, so that the adjustment of the connection and the frequency do not essentially affect each other. <IMAGE>
