This is the active FM receiver antenna amplifier, used to boost the FM signal catch by the antenna, you may call circuit “FM antenna booster”.

By working with only a small handfull of parts you can assembled this kind of reliable FM amplifier circuit. It runs with only 1 UHF/VHF type transistor, MFE201. This amplifier will pull in all distant FM stations clearly. The circuit is configured as a common-emitter tuned RF pre-amplifier wired around VHF/UHF transistor MFE201. You will find a couple different models that probably would work too, like the NTE107, 2SC2570, and so on.

Adjust capacitor trimmers C1 and C2 for the best gain. Input coil L1 consists of 4 turns of 20SWG enamelled copper wire over a 5mm diameter former. It is tapped at the first turn from ground lead side. Coil L2 is comparable to L1, but just has three turns. Pin configuration is shown within the diagram.
