But! at 80' a 10' turbine has great bending force, this is realy (as usual for towers) a matter for a structual professional.
I suspect the diagram posted was a simplified diagram only, which to me conveyed the posters intent.
If one does not have room for guy wires for an 80' tower, I suspect one does not have room for an 80' tower. People/buildings/dogs etc should at all times reside well away from a tower's reach.

Even in light of this consideration, though, A-frame towers would still be worth thinking about for sites where locating the side guys is unfeasible. Ridge tops come to mind, if they aren't too turbulent.
Does anyone actually know what kind of forces turbines of given sizes apply to their towers under given wind loads? This would be handy information to have...[ Parent ]
So treat it like a sign mounted on a tall pole or tower. B-)[ Parent ]
Thanks for your reply. Yes the figure I posted was a face view. As you suggested, side view would be just like any tilt-up tower, guyed in both direction at the top and probably at two other points. So I thought no use to post that. Sorry if there was confusion in my post. I may have to guy the side of the A frame too...??
Must I understand that the towers that another poster sead were around for decades are totally freestanding? It is not what I wanted since I want something easy to access for maintenance and I don't want to have to climb although I think it might be fun the first time but not if I had to do it every year.
I understand 80 ft is high and I would have to make sure everything is calculated to withstand the loads. 80 ft is not totally set in stone yet. Our lot is 2 ha and is sloping towards incoming dominant winds. Trees are not as high as 60 ft yet but will be in a few years. I Just wanted to know if anyone had tried this. So, has any of you?
