Hi to all!
In my club we are building a groundstation, and we want to make two LNA's one for VHF and other to UHF eggbeater antennas. Someone can share a circuit to do one for each band??? i can't find it in google (maybe i'm searching wrong).
Hello Mati,
I've had good luck with the following simple preamp.

I have not measured the NF, but the construction site claims 1dB.
Good luck!
