I agree entirely - the challenge is to model a tower and two multiband
yagis with sufficient fidelity.

It's quite possible that the addition of a beam at 60 ft. could cause capacity

I have a 100 ft tower with jk mid tri 40 on top. When shunt fed, it
was pretty competitive on 160. Recently the antenna seems to be a few
db weaker. The only change was adding another beam at 60ft. Could it
have had an impact? Adding the beam only marginally affected the match.
