you could work a few dozen of the larger EME stations on 2
meters. You could do this much more quickly if you had at
least several hundred watts.
To work another station like yourself you would need 3 to 6
dB more antenna.
Of course, with heroic efforts (long averaging times, etc.)
one can make QSOs with less.
On 432 MHz you can work a few of the larger stations with 50
W and a single long yagi. Two 4-yagi stations can probably
work each other, but maybe not with 50 Watts ...

- Hi All,
About how many dB of gain should I be looking for in a 432 MHz Yagi? Is a pre-amp needed as well?
Thanks and 73,
