Great information Dan!

I have always just guess when converting a tower to a wire diameter.  
The original poster seemed concerned that his tower would effect his  
horizontally polarized HF beams, I have not seen that occur.

As a comparison, the lower-right of this image shows both the Leeson
and Wikipedia equivalent diameter for a Rohn 25G cross section:

AutoEZ users, the Leeson and Wikipedia formulas are on the Variables
sheet tab for the "Bent Dipole 4-sq" *.weq model files as described in
the first section here:
