Welcome back. Sorry to hear the bad news. This is your previous thread, but your tvfool report is no longer on the server. I saved an image of it in the attachment.
Loss of channels

Is this estimated report close enough?

The 7084 is a BIG wide antenna because it covers VHF-Low channels 2 to 6, in addition to VHF-High (7-13) and UHF (14-51), Those are real channel numbers, not the virtual channel numbers (which are usually given in decimal form to avoid confusion, like 11.1) that you have been using. It is the real channel numbers that determine what antenna to use.
The 7084 could be replaced with the HD7698P for equivalent performance without VHF-Low, but you might be able to replace it with the smaller HD7694P if you could get it a little higher. You have a lot of trees in your area. Let's see what the other guys say.
2.1 and 8.1 are two of your weaker channels and a preamp would probably be overloaded by WATC, so the gain for them has to come from the antenna only.
Even at 50 feet WSB ABC is still a weaker 2Edge signal.

And WRDA-FM might be strong enough to interfere with ABC:
