K8RI:  > A heavy duty rotator with a large antenna should be mounted well
down into the tower. Mounted at the top, in the tapered section would
likely put very high stress at that point.

I mounted my rotator at the same point in 45G and had no problems for >10
years with the antennas/wind speeds in Colorado described previously.  If
still concerned, you could mount a straight 25G section above a straight
25AG4 and install the rotator in the 16" window.  Of course this would
require a long mast (~15').  I don't know which LPDA Jeff is considering
but I doubt it's >32 sq. ft.
