[TowerTalk] screw anchors in sandy soil

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 
HB conglomerized bracket, and attach the guy to *that*, and sleep  
well......

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.
