I seem to recall someone who built a dual 40/80 4 square using a tower
in the center for the support, and hanging wire verticals from 4 guy
lines. There was some modeling and test data.. I'm pretty sure it was
on this list, so an archives search might turn it up.
From a modeling standpoint, the tower cross section is 'small' compared
to wavelength, so you could probably model it as one big fat wire made
of steel.
