I installed the smaller WT-51 tower. I contracted a tree-service
contractor who came to my QTH with a Bobcat and a 36" diameter auger
used to plant trees. He "drilled" a 36" diameter hole 6' down in about
15 minutes. I think the total was $115. After 12" down, it was all
undisturbed soil to the bottom! Then I poured 1.5 yards of concrete
into the hole. It's been rock solid.
I agree with the other posters on getting another back hoe operator.
Back-fill is NOT undisturbed soil, so beware!
73!
