their brackets are still steal, they will rust, i guess i should have
said i need the brackets to be either aluminum or stainless

any chance you know of a place that has those my usual places don't
carry them

One possible option is to check around at marine-supply companies.
They seem to have quite a few different stainless-steel antenna
mounting brackets of one sort or another. Rail-mount brackets seem to
be the most common, but stick-out-from-a-wall mast brackets are also
available.

"Make it out of stainless, call it marine-grade, and multiply the
price by 5" seems to be the usual approach.
