     Well, considering that the guy wire is rated for 4000 lbs., one screw-in
anchor won't have enough holding power. If you're talking about using 2 screw-
ins per anchor, that should give you enough capacity. 

     BTW, there are seven grades of soil and capacity. Unless you have a
geotechnical soil analysis done, how do you know which one you've got? That's
one of the reasons that Rohn specs anchors in concrete - it's more predictable
than using screw-ins.
