Google Earth view. House is marked at WHITE ARROW. The picture has NORTH on the LEFT, EAST at top. The Red X is where the antenna would be. According to google earth, the yard sits at 575' above sea level. The WHITE X marks the highest point, per google earth at 645'. Mind you there are oak trees which are taller. Beyond this highest point, it drops off...straight shot to Boston.

I am about 10 feet below where the antenna would be. There is a maple tree to the left. The camera is about 18' off the ground.
