With this setup and a single long yagi (say 10m boom length) 
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 ...
