I live in West Central NH, a semi-rural area. The cost of my Rohn 55G base
and guy anchor footings was about $2,000. However, I built to the Rohn 110
MPH spec, so the guy anchor footings are twice the size of the typical 90
MPH spec used by hams.
The cost above includes equipment and labor for excavation, backfill,
concrete, shuttling concrete from the driveway to the tower site, rebar (cut
to order) and form. I participated heavily in squaring up the holes,
building the rebar cages and building/removing the base form. It was a lot
of back-breaking labor for me, even with excavation equipment run by hired
professionals and a helper for the other tasks. The tower is on a steep
hill, which made my personal labor expenditure all the greater (lots of
climbing down and up.)
The concrete alone cost nearly $800, due not only to the 110 MPH spec, but
also the realities of digging deep holes in ledgey terrain with a backhoe.
It's very difficult or impossible to dig perfectly squared holes exactly to
Rohn spec with excavation equipment. You end up with larger, more irregular
holes, which require more concrete.
I sometimes wonder what it would have cost had I outsourced 100% of the job.
I think it would have been $500-$1,000 more.
These costs were a relatively small fraction of the overall cost of building
the tower and populating it with four antennas and four rotors, even though
I did all the climbing myself. In retrospect, I probably should have hired a
contractor to do a turnkey job on the base and footings.
