[TowerTalk] An Engineering Question

[Bill Hinkle]

I take the 2 vertical broken lines to be the guy anchor. The lines on a
45 degree angle to be the back stay. The single vertical lines go to the
ground and are anchored into concrete. It will help the elevated anchors
become more ridged and tend not to bend. Sounds right to me. Did I miss
something in what follows?
