Galvanized or Stainless Steel for mounting an antenna?

Quick question here for me before I go out and buy some brackets, nuts, and bolts for an antenna I bought off eBay. How long will galvanized material last if I use it to mount my antenna? Would I benefit any more if I use stainless steel? Stainless steel has gone up in pricing a bit, so if I can get away with galvanized nuts and bolts but not have any problems with rust or corrosion, I'll buy that instead. Thanks.

Jim, :welcome:
Until last summer I had antennas in the air on a 40 foot telescopic mast since 1985, exposed to salt air from Puget Sound in Seattle. I used annodized steel fasteners and 'U' bolts and everything dissembled without a hitch. However, I used a copious quantity of RTV (silicone rubber) on the 'U' bolt threads and 'F' fittings. Next summer when I finalize my new antenna array I'll do the same. Works for me!

I feel that either stainless or galvanized will outlast the antenna itself.

When using larger Stainless U-bolts there is a potential for galling. I use Brass nuts with stainless U-bolts to solve the problem.
