I'm doing exactly that.
But The horizontal portion of my feedline as it leads away from
the vertical dipole is not exactly horizontal, it drops down
at maybe a 30 degree angle for about 8' , then it drops
straight down vertically to the ground.
I am getting the feeling this could be part or all of the problem.
Yes. That's what I meant when I observed that the feedline becomes part
of the antenna. It would be pretty easy to model in NEC -- all you need
are the endpoints of straight portions of the run, and an approximation
would be enough to show proof of concept.
