Huh?  what gravitational effects do you have in mind? I know 
gravitational fields can change space-time, and thereby the path of 
electromagnetic radiation, but in what way would you have in mind, and 
are you sure you want to start including relativistic effects?

And are you sure you want to account for the propagation paths?  How do 
you decide  how many hops are involved? Short path or long path?

If all you really want to do is equalize the antenna questions, why not 
use ERP rather than merely power?
So you would have the power out, - coax losses, +/- antenna gain; that 
seems relatively fair doesn't it?

I think the modified formula using ERP on both ends would normalize for 
this, wouldn't it?
