New goal cleanup 8 10 and 36, also pickup the FOX analog rebroadcast of 32.
#1? The current antenna is not good for UHF (14-69). It also maybe 40 years old.
#2? Should I add a rotor?
#3? Why does the 8' antenna ht provide better values.
#4? Keep current antenna and add UHF specific?
You need to avoid the trees, whether by going over, around or putting them in the fireplace. If you can't do that, this is a futile effort.

You've seen what the existing antenna does with 8 & 10 already, which leads to questions #1 & #4 - It's clear from the photo that the antenna is a VHF only design, it never was intended to receive UHF frequencies. It's bent to the point of needing to be replaced. The Y10713 is the best option in a cut for band H-VHF antenna that covers those two channels.

A DB8e is not overkill when aiming for WLEF to the south. It may produce a viewable signal from CH-32 when aimed at CH-36.

#2 - A rotator would be helpful when trying to fine tune exact aim point. Given the intention of serving only one TV, It may prove helpful if you want to optimize the reception of CH-32 & CH-36.

#3 - The Longley-Rice model used by TV Fool is known to exhibit this type of behavior. Sometimes the estimate produced is quite accurate, though in other cases, the axiom 'your mileage may vary' is quite apropos.
