I use only three guy anchors for my tower, which has four sets of guys. It
would seem to me higgly unlikely that a guy anchor would fail, but I have
seen it happen.
In most cases you are right. After hurricane Charley I was in Punta Gorda
within 24 hours and had a chance to see the damage first hand. Along with
other tower failures I saw two toppled towers, both of them Rohn 25 had
anchor failures. Both were in substandard soil conditions..very wet. Rohn
warns about substandard soil this in their catalogue for specs.
Generally though, if the anchors are built to specs I think one set of
anchors is sufficient.
