Good thought. I hadn't considered that it would add force to the base point. I had considered tho that I could further stablize the base by adding a concrete form around the guy attachment point and encase that attachment point in some quickrete to further stablize the base

The steel being free to bend right now must absorb some of the lateral force, and you'd instead be transferring all that force into the base. I think it would reduce, but not eliminate lateral movement, but it would increase stress at the point where the guy wires are attached to the base. I think you'd be better with the sidewalk guy. I'm not an engineer, but I play one on TV.

Or at grain elevators, if they can’t put the guy anchor far enough out, they will sink an I-beam and attach the guy to the top of that.

I would think rigid enough struts would probably be massive and so heavy that the down force would exceed the base load, but what do I know. Probably would cost less to put up a self supporting tower at that point anyway On Mon, Dec 21, 2020, 9:20 PM Craig House < [ mailto:[email protected] | [email protected] ] > wrote: BQ_BEGIN The attached drawing is rough but I hope you get the idea. It is not the tower in questions but is a photo I had I could mark up I have a customer that has a tower in the very corner of their yard 90 degree angle corner. Best I can get in the yard is one guy wire and the neighbor is not an option to put guy wires in. 25g 50' tall. I'd like to make it more stable but how? The base is in concrete and has been there for some time. Heavy winds have not caused damage to the tower so it is not about how solid it is as much as how much it moves Would a guy wire design where all three legs were guyed back to the base of the tower using some kind of stand off in the middle do anything? I think it might make the tower more rigid but would it keep it from swaying? Since some of the unstableness of the tower comes from the joints it seems like it might help but is it worth the effort? I maybe could move out 3' from the base but that angle just doesn't do much more than attaching to the base just above the concrete.
