Hey, thanks very much guys. I got really suspicious of the method when
it told me an adequate stacking distance for two 70 cm beams with 10
dBd gain was 0.04 ft.
I was looking for the quick answer but guess I'll just have to model
it. Looking at a C4SXL, plus 6m, 2m and 70cm yagis on the same mast.
