Tuning apparatus for very high and ultra-high frequencies, characterized in that it comprises a radio frequency block adaptable to two complementary frequency bands within the selected operating range, with inputs for independent dipoles for said bands and whose output feeds a formed chain by a radio frequency amplifier stage, an intermediate oscillator stage and an auxiliary amplifier stage from which the circuit output is taken, these steps being associated with a two-position switching device corresponding to the selection of both complementary bands, so that in the position of the upper band, the three stages work respectively as radio frequency amplifier, self-oscillating mixer and auxiliary amplifier, while in the position corresponding to the lower band these stages work as radio frequency amplifier, independent oscillator and mixer, respec tively.
