As usual, you're right. Diameter would have to be significant portion of
the wavelength, as I understand it, to affect bandwidth. At 20 meters, even
the stuff we use on high voltage transmission lines would be only a portion
of a percent. Just the sight of such substantial hardware in the air for
your operation might add a few dB to the 'boast level', but would probably
not significantly affect real operation. Of course, an antenna made out of
4/0 wire would not be cause for worry during the occasional ice storm,
assuming one had sufficient towerage (is that a word?) on which to hang it...
