But let's see here, guy wires above head height >= say 6 feet. Therefore 40% of x = 6 feet. If I recall my algebra correctly >x would = 15 feet. Which would equate to 9 feet in the ground?

A 10 foot i-beam is plenty. Don't scrimp on the concrete though. In average soil it takes much more concrete than one might think to keep the post from slowly leaning over when under constant tipover force of a few hundred pounds at 6'. 2 or 3 yards is NOT too much. -- Steve K8LX ```
