You are right about HIGH ANGLE close in signals. Rotating it does not
make much difference. There IS a difference at low angles. You WILL
have a dickens calling stations in EU if your rotatable 40m dipole is
off the end toward EU.
The BIGGEST advantage of a rotatable dipole up there at 70+ feet? That
it's up there at 70+ feet, and a dipole up over 1/2 wave on 40 meters
is really a pretty good antenna for DX.
Being rotatable also means you can keep it in fixed orientation to a
tribander or such close to it on the tower. It happens frequently that
one must put the 40 meter rotatable dipole at right angles to
tribander elements to keep from messing up the tribander's performance
on 15 meters. Can't do that unless it's on the mast with the tribander
and rotates with the tribander.
