Be REALLY careful with the HyTower base specs!
I also just purchased one (actually got the tower itself for $60 and then
purchased the remaining parts from HyGain/MFJ).
Our local building dept (Benton County, WA) required a signed/sealed base
design by a Washington State licensed PE; when I had mine done (references
on request); they actually did the wind load calcs, and for an 85MPH wind
(I think that's called "Class C") they came up with a 4'x4'x5' (5' deep)
hole. I'm definitely going to have mine trailered/trucked in.
