[TowerTalk] AN tower

[Kevin Stover]

That's the youtube vid I saw last week.
There's got to be several hundred yards of concrete in each pad.
The concrete trucks and pump look like toys.
It's interesting to me because Iowa leads the nation in wind turbine 
energy production followed by Texas and California.

I have seen AN Structures and Trylon tower members together.
The AN steel members are an estimated 50% thicker and the bolts are larger.
If I'm reading the AN allowed area file correctly an HD70 will take the 
average Ham tower load of 12-15 sqft all the way out to 130 mph. Trylon 
doesn't make anything that heavy.

The antennas and your neighbors houses will start coming apart at 100mph 
but your tower won't.

That's assuming the creative engineering of the base is minimized. The 
prime directive is in effect.
