The increased gain of the earth station antenna compensates for the path loss.

On 10 Ghz: So we would try to get just enough gain to illuminate the earth but Ooooops, that won't quite get it because the path loss at X band is much higher and would not allow for the ground user terminal we would like to support. If you overcome the path loss with gain, you do not illuminate the visible earth. Any phased array we are capable of building I don't think would allow for continent shaping of the beam and if it could, would we really want to be unable to work the DX in the middle of the Pacific Ocean?
