Bird's (Or Pilot's) Eye View

I got to wondering about that radio mast array, shown both in Paul's picture of Chaise at the Central Florida Fair and in Peter's moonlit Digital "Painting".
I've identified them on the air chart in the top photo - the symbol shown, M-like, indicates there's more than one mast, and the symbol shape says they're under 1000' (in fact, they're listed as 420' tall). The second photo shows all 4 mast bases.
