It's not the height above ground that effects CMC. It's the length of the mast in your model. Take the resonant full wave mast and place it 40 feet above the ground and you'll see it's the mast length. Furthermore, there seems to be some imbalance in the location of the source that is making the CMC appear worse than expected.
