Getting further away from the trees always helps, but finding a clear shot thru the trees is even better.
You can always try a temporary test of another antenna location without making it permanent.
If that doesn't work, then maybe the next step would be a separate antenna with a little more gain for FOX like a DB4e or a 91XG with an A/B switch to switch between antennas.
WLYH is probably too strong for you to use a preamp for FOX unless you use a single-channel CH 47 band pass filter between the separate antenna and the preamp.
Your tvfool report doesn't take into consideration the signal loss caused by the trees.
