The solution concerns the connection of the inductively tunable dual duct box UKV, which contains, in series with a tuning coil (1), a connected additional coil (2) and a switching diode (3), which switches this coil. The merit of the connection concerns the fact that the input terminal of the first condenser (6), which tunes the oscillating circuit, leads to the aerial end of the tuning coil (1), while the output terminal of the first condenser (6) is connected via the second condenser (5) to the ground terminal.<IMAGE>
