I'm trying to digest all of it as I'm admitted novice here lol.

I'm still learning too, Bud.
Thanks for the photo that ADTech requested.

It's dead flat around here not much if any elevation change.

The antenna is aimed due south about 16ft up with no trees within about 600ft any direction.

here's the view from where I would like the antenna about 25 ft up

Nice photo, but UH-OH, could it be higher? Trees really mess with UHF signals.
The hdtvprimer site is down now, so no images. Text from Google cache.

Trees and UHF
If a tree loses its leaves in the fall, reception behind it will improve dramatically. Many people get a TV for Christmas, and erect an antenna for it in January, and then wonder why it quit working in May. It’s the trees.
In the following simulation, a tree is modeled as a perfect sphere blocking 90% of the signal.
(image missing)
If the antenna is behind a tree, it is in overlapping fields: a weak field that passes through the tree plus a weak field that is diffracted around the tree. Overlapping fields are complicated, with strong spots and weak spots. This will be true even if the tree is not a perfect sphere. If you get a UHF antenna to work behind a tree, you will likely see dropouts when the wind blows because the strong and weak spots will move around as the tree deforms. Even in a good-signal neighborhood it is inadvisable to put a UHF antenna behind a tree.
The farther away a tree is, the less of a problem it is. For far away trees, assume no signal penetrates the tree, and reception will be by diffraction around the tree. Trees block 100% of satellite signals.
