First thing I would say it to literally model your back yard,
including all your antennas and feedlines. In the same model. That
may cost you some for serious models that will handle that much wire.
Or you can visit a friend who has the software and do it on his.

I'm not surprised at your findings in light of my experience. Regarding the
ATUs being able to tune in this case, I'm not surprised. Elecraft tuners will
match nearly a complete open and short...been there, done that. I really
wish they were limited to something like 6:1 to prevent

via the stud.
I found 2 things:
# 1 the manual tuner settings required for 1:1 match changed on all bands, but

I would strongly suggest that is an indication of a problem in your
antenna system somewhere (my first guess would be between the
transmitter and the balun). I would start by substituting the coax to
the balun.

That suggests something wrong with your antenna system.
