I have a 30 foot mini tower with a hex-beam on it.
My property is pretty much all solid ledge which is exposed or covered
by a few feet of dirt.
For the base of the mini-tower, I drilled down a couple of feet and put
in threaded rods with a washer and nut inside.
I set these in place with expanding cement.
Its been strong for over 5 years with no problems.
