All electrical considerations aside, one may take into considerations the
mechanical qualities of 'Stainless Steel' alloys (which are actually NOT a
steel in the traditional sense.)
If the intent is to create the 75-Ohm feed as part of the antenna wire, in a
contiguous piece, via spacers or whatever to configure a 'ladder', fine.
Otherwise there will be a mechanical connection from the feedline to the
elements, as you will likely find that 'stainless' does not solder. There will
be a compressive joint, be it a binding post, wire nut or what have you. This
is actually a desirable connection, in my mind, for audio, and that ends at
about 20 KHz. I solder the few connections I have to make in wire anyennas. I
might add that in about 25 years of prototype production I worked or worked
with a couple forms of stainless - cast, sheet and shapes - just often enough
to farm the work out to shops that were set up to work stainless. Some of these
ONLY work stainless. It's a great material with wonderfull qualities, but
unfortunately the casual use of it in fabrication is not one of them.
Just my 2 cents . . .
