Lee es Group,
One "personal experience" hint:
If you can't pour the concrete the same day as digging
the hole (scheduling/inspections/etc.), make sure your
hole AND 2-3 feet around it is covered with boards/tarps.
I had major rain hit one of my projects, resulting in the
clay walls falling in. (Ended up buying more concrete
than I planned) This is more of a problem near a structure
where you have rain collected by a roof/gutter system!
I also recommend snow/construction-fencing the hole
while the hole presents a potential hazard.
Observation by a non-ham: Isn't this a lot of work just to
scare yourself putting antennas
high in the air??
