I wouldn't attribute all of that to height -- what you can HEAR is primarily the result of antenna directivity and noise rejection. Windoms are notoriously bad for noise rejection, because they are badly unbalanced, so noise picked up on the transmission line couples to the antenna. Windoms also have "random" directivity on each band.

Also, it's worth studying N6BV's excellent work on High Frequency Terrain Analysis in the ARRL Antenna Book, and also modeling in NEC. Higher is not always better.
