Hello,
I need to build a very small antenna booster for a radio working on WFM mode on 120-140 MHz. It must be as small as possible, and the most difficult thing: The receiver works from 3V...
I found several designs using a bipolar - but they work from 9V to 12V.
Any help please?
TIA,
Nina

Thank you very much vfone,
I have a roll of MPSH10 - maybe I'll try to build a preamplifier - and I thought that maybe changing some values - it may work...
Here is the simplest one I could find:
I think :?: that I even don't need the L1 and TR1...
Any suggestions of using MPSH10 instead?
