I had one of these towers in the 80's with a Hy-Gain HDR-300. This rotator required frequent service! I had to extend the tower a little and blocked it with 4x4's before climbing up to remove the rotator. BTW, this was the last Hy-Gain rotator that I have owned.

Has anyone been able to swap out a Yaesu G2800 rotor mounted on flat plate
inside a US Tower 89-foot crankup with the tower fully nested? This would
involve separating the 3 pieces of the rotor while still inside the tower
and wiggling them through the diagonals. Looks like it might work but a
tight fit. I don't have a spare G2800 available to test this.



Normal alternative would be to rent a boom lift and extend the tower so
rotor is in the clear, then remove and replace. From previous experience,
this requires a 45-foot boom lift or longer. Other alternative is to tilt
the tower over, remove beam and extend horizontally, but that is not
feasible in this case due to obstructions.
