Thanks for the flowers Ron. The one compromise I ended up making was not
getting the aluminum up a full half wave in the air. Fully half the
directionality is down a steep hill, so electrically it meets that criteria.
However the other half is back into the hillside so in that direction not
Actually I should have said 130 feet up!

Beautiful installation Eric. A rotatable dipoles offer an advantage when
they are up high enough (>1/2 wavelength) to provide significant
directivity.
Unfortunately that is a little difficult for most of us on 80 meters where
the antenna is 130 feet long and needs to be 65 feet up, but some have
Rotary dipoles work! It's remarkable how directive a dipole can be. And you
don't have to worry about LP vs. SP propagation.
I also have a full size 20m version. I wrote an article about how I made it
work on all the bands from 40-10 meters with high power (1.2 kW):
