> you will most likely not install both beams at one level.
When one will be stacked above the other you cannot just add the wind loads.
The upper one puts much more bending force on the tower then the lower one.
You probably have to lower it during high winds or support it with guying.
Guying it won't be helpful. You can only guy the bottom section but
the failure point will be in the un-guyed upper 1/3 or so of the tower, not
the bottom section.
