Yes. Just check the geometry of the tilt plate ahead of time. I helped install
one of the humongous Steppir beams on a friend's (W7EXG) tiltover tower.
Because the boom diameter was larger than the plate was designed for some
rotational bias had to be used to have the beam horizontal when the tower was
upright. This had the elements dragging the ground when the tower was tilted.
It took a bunch of people lifting them over the cactus patch we were working in
while cranking up the tower. Fortunately the fiberglass elements were flexible.
(A fix for this would have been some spacers under the pillowblock bearings, but
Bill wanted to proceed while he had a crew.)

## The real trick will be.... with the tower in horz position, mounting the
yagi onto the mast. The eles of the yagi cant be 90 degs to the mast, or
the tips will be embedded into the dirt. Eles will have to be inline with
the tower. If the els are really long, like a 30M yagi, then you also have
to worry about the nested height of the tower vs one half of the 30M ele
length. Once tower is moved to the vert position, somebody is gonna have to
go up there, then rotate the boom clamp assy, by 90 degs so the eles are
parallel to the dirt.
