I believe this is why WMCA in NY never built the 50Kw CP that they let lapse. 
By building it, they'd have had to throw about 90% of their power into a 
flashlight beam out over water, barely skimming the south shore of Long Island. 
They'd have lost about 70% of their signal over CT and Long Island by doing 
this. It obviously made much more sense to them to stay 5Kw with a less confined 
pattern.

Anyone from (or familiar with) WMCA is welcome to chime in, correcting me if 
I'm wrong. :)
