I-beams are the way to go. 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? I think this 
is a bit much for any 70 foot tower. Put the i-beam in the ground 4 foot 
with rebar and Johnson studs with concrete and it will hold anything you 
want to put up. A 10 foot i-beam is plenty.
