Most respectfully, I think the topographic data in this case is flawed or there is at least a difference of interpretation. Having walked through those woods to the north-west of my house, the ground is all very flat, with maybe a five-to-ten foot change in elevation at most through there. The tree-tops however are about 50-feet tall, and I think that is what the google-earth data are showing at point "B".

In fact, the Google 3D-view shows evidence of this. There is a small clearing in the middle of the woods 1/4 mile away along the signal-path that shows as a depression in Google-3D. That is definitely not the case.
