Once you have the hole dug, you really don't have much choice Tom....
because you want the concrete to come about ground level. Usually, you want
the concrete 4" or so above surrounding grade. I typically form the top of
the concrete with 2 x 4 board on their side to give me a 4" height of
concrete. This concrete can then be worked to make the top of the concrete
somewhat domed. I want most of the rain to simply roll of the concrete.
So in my opinion, fill the hole and have enough to fill the wood forms at
the top.

Tom,
My opinion is to fill the hole with concrete and put one set of guy
wires on the tower. Take the guy wires off to lower the quad if needed
on a calm day.

I am very sure this has been done several if not many times...but...
How much cement do I really need to install my 40 foot Rohn 25 with a
two element Cubex quad and make it freestanding.
I have a 3x3x3 foot hole, but I seriously doubt that it needs to be
full... or does it?
Thanks
Tom K5IID
