How did you dig your tower base? Often times it is easy to dig a hole
with a small backhoe and use a standard concrete anchor.

So I have been trying to put up a 50' 25G tower for a little while now. I
bought some 6'x8" screw anchors thinking they'd go into the clay soil
pretty easily, and they do...for about two feet. Then they hit rock; I am
pretty sure it's bedrock or something similar from talking to my
neighbors. Obviously that's hardly enough earth for a screw anchor to hold
on to.
What are my options here? Looking at Rohn's drawings, I am entirely sure
that going down 4' for a concrete base is out of the question. I am
currently thinking I'll bust a hole about 8" around down maybe 3', dig an
angled trench for the bar of the screw anchor, and set it in the hole with
a bag or two of concrete. Hand digging that hole doesn't sound fun,
though.
For what it's worth, I'm in central Missouri.
Thanks!
