Jim, Thanks for the link. I have saved the presentation so I can revue
it as desired. A bit late to impact my next project as the tower is on
order and the antenna is on the shop floor in 4 boxes. The good news
(whew!) I don't think I am in violation of any of the things you
pointed out. The tower is a Tashjian DX-70 and the antenna is a 6m-80m
Yagi. Well, the 80m is a dipole but the rest is a Yagi.
Thanks again for sharing.

I don't do many A-B comparisons between the OCF dipole and the
vertical anymore, having seen the results so many times before.
Rarely does the dipole win a shootout by much margin. results are
close but the vertical usually does a little better. One solid
exception is contacting a friend 120 air miles away. Sorry, senior
moment (CRS), I don't recall the band but the OCF worked him well and
the vertical was useless. We chalked it up to takeoff angle. This
result is repeatable.
Not surprising. See http://k9yc.com/VertOrHorizontal-Slides.pdf
The problem with OCF dipoles is that you can't choke them to kill the
RX noise.
