At that cost...easier and cheaper to pour a sled.

If the soil is questionable, you could always screw in 2, 3, 4,...N such
anchors adjacently, lash their eyes together with a big chain, or some other

After Hurricane Charlie roared through Punta Gorda in 2005 I had to make
a
tower delivery to Clear Channel for a back up link the next day. I saw
several tower failures with screw anchors yanked out of the ground. Wet
sandy soil was evident at the anchor points.
I have FL sugar sand at my QTH and have used screw anchors on only one of
the towers...a 65 footer with a light load. The screw anchors on that one
are 8 feet long and are the same ones the power companies use. The 200
footers are all guyed with concrete "sleds" 7 feet wide, four feet front
to
back and 3 feet thick, buried 5 1/2 to 6 ft deep with enough rebar and
concrete to build a small house in FL. Pretty much to Rohn specs.
