Pre amplifier for ultra high frequencies, characterized in that it consists of a transistor whose emitter-collector circuit is interleaved in series in the antenna circuit, to which end the first of these elements is connected, on the one hand with said antenna through of one step capacitor, and on the other with a variable tuning capacitor, while the other element is connected, on the one hand, with the antenna circuit of the receiver through an inductive coupling device, and on the other hand with a variable capacitor for the impedance adjustment.
