All 7 of my towers are held by screw in anchors in Alabama clay
(which gets hard as a rock in the summer).  Up to 80 ft., I use
one anchor per direction.  For 90 ft to 140 ft, I use 2 anchors
in each direction, with the first anchor spaced 60 ft holding 3/16 
inch guys attached at 30 and 60 ft.  The second anchor is 
spaced 80% of the tower height.  The top guys are 1/4 inch.

For my short towers (40 and 55 ft), I used 4 ft long screw anchors
with 4 inch plates.  For the taller towers, I used anchors with
6 inch plates and either 4 or 5 ft shafts.  Galvanized anchors
are best.

Some of these towers have been up for 25 years and all survived
a small tornado that took out dozens of trees in my woods 
including a 75 year old Oak and 75 year old Beech 5 years ago
(estimated winds 90 mph).
