must be extended to access the rotator plate.
Hiya, Brian --
You don't need to remove the antennas and mast. Run the tower up far
enough so that the rotator is accessible, block the bottom of sections with
2x4's or pipes to prevent downward tower movement and go on up. You can use
a comealong to lift the mast up enough to clear the rotator or a pry bar
of some sort. You can get the mast up enough to do the swap and then it's
pretty straightforward.
