True. Eventually I would like to invest in a antenna tracker at the 
ground station.

Not really. But since I fly 2.4Ghz the range is not terribly long and I 
wonder if I might get better reception at the fringes of the range.

Anyway. I just wonder if the wondrous advantages the FPV guys keep 
harping around would apply to us. :)
