...which would lead to the question:  If one were to design some sort of
remotely controllable tilt mechanism (sorta like the "el" part of an
az-el rotator), could one control the takeoff angle, and thus have only
one antenna to cover all distances (assuming it was mounted high
enough)?  Seems like if you tilt the beam upward, the takeoff angle would
be increased accordingly, so if you were shooting over the top of a
station, state, or country you wanted to work, you could just increase
the takeoff angle until you reduce the radius of the skip to place your
signal right where you wanted it.  Why didn't someone think of this a
long time ago?!?
