Thanks Rabbit for linking the prior thread.
Bigbear, are you running the preamp still?
How many TVs are you feeding? Are you using a distribution amp? How long is your coax? Are you aimed towards nearby trees?
That antenna if operating normally should be more than sufficient to receive your locals. It seems your addressed many of the components that were due for replacement.
Much to unpack here. The bottom line is your TV fool report is pretty good for signal access. It's the immediate vicinity around the antenna I'm interested in.
