To be honest with you, I wouldn't purchase/install one either. But your
initial post offered none of the aforementioned insight.
Yes, 45G is the accepted standard for any 'serious' installation. I know
Matt and he has just about as much tower experience as I do. If someone were
to ask me, I'd probably give them the same advice. Nonetheless, aluminum
towers still have to meet windspeed forces and engineering calculations,
standards and codes just like steel towers.
And you're comparing apples-to-oranges since the aluminum tower is self-
supporting and 45G is a guyed tower.
At TowerTalk, we give lots of creedence to actual data. The same isn't
true with hearsay and anecdotal information.
