Well guys here is an Eznec model I did of Homer's 11 meter Moxon at 36' feet. This is not to suggest that these models will show the exact result Bow and M0GVZ might experience with their physical antennas, but these models might give us a clue for the effects and the differences due to a simple change in height. I lowered the model to 17' feet in order that Bow might get some idea of the change in performance he could experience.

You will notice a little difference in the maximum gain of 11.39 dbi at 14* degrees on the 36' foot mast vs. 10.26 dbi at 28* degrees for the 17' foot mast, a really big change in angle.

For an additional comparison, I added a pattern of the 17' foot model with the angle cursor set at 14* degrees above the horizon. This compares the maximum gain and angle of the 36' foot model to the 17' model at the same 14* degree angle.

Good luck Bow.
