The telecommunications tower industry routinely uses galvanized steel cable all over the world in any climate. Freeze-thaw cycles are not detrimental, but you must account for the seasonal thermal variation in the cable. You must also account for wind excitation (galloping), cable tensioning, ice accretion, etc. I would suggest you look at the EIA 222-G. Troitsky's "Tubular Steel Structures" has a section on guyed stacks. ASCE 52 is the guide for FRP stacks. When you guy a stack, you will induce a significant compression force in the stack. I am not sure how the PVC will work in compression.

I have a situation where I plan to use cable splays to horizontally support a small, 7 ft tall PVC stack on the roof of a 2 story building in snow country. Should I be looking at stainless steel or galvanized cable? Will the freeze-thaw cycles be detrimental to the exposed cable?
