I was tempted to write a sarcastic proposal that you simply build a 200 foot tower in the center of the sub division... the whole thing need not cost more than a few hundred thousand.
I won't bore you with the fun details (which would perhaps tickle my imagination a lot more than yours??).
How big is this subdividsion. What kind of homes (one story or two?), what kind of trees, hills, and basic topography? Any predominate high points for good antenna locations (or obvious low points that will be hard to reach)?
Absent a handy 200 foot tower, would a cell phone be a better idea?
