Gonna take a while to replace a 3-tower phased array like that.
We could hear WWVA at night in Newark, New Jersey.
Just depends on how much money they want to spend. I know several tower crews that could have 3 guyed towers stacked inside of a week. Doesn't take that long if your crew really knows what they are doing, but if you hire a crew that really knows what they're doing it ain't gonna be cheap.....
