Copper is kind of ugly and tarnishes which I would think would increase

Stainless will not work very well compared to copper unless you plate
it. Way back when I knew of a guy that plated his 10 meter ss whip
antenna. silver over copper over nickel. ( I think he worked for bell
labs at murray Hill.) That antenna worked much better than the standard
10 meter whip...

Stainless will get hot with rf flowing through it or along the surface.
Ive seen it happen when ss bolts were used on a hi power rf feed
through.
