Nope, antenna gain, a byproduct of its directionality, is absolutely 
bi-directional unless there is something in the near field to absorb 
power.  Pringle cans are wunnerfull things when you need to reach several 
miles, the record being 39 miles I believe. A google search will spit out 
at least 50 designs based on the original pringle can idea.

And if the moon wasn't such a sponge due to surface roughness dispersion 
at those frequencies, a couple of 10 foot well shaped old c-band 
satellite dishes could probably be used for moon-bounce.  Their gain 
would be 50 some db if still in good figure.
