I doubt that the difference in resistance between stainless and copper
is going to cause any significant additional losses in a whip antenna.
That difference will be small compared to the other losses. Stainless
is often used for whip antennas because of its mechanical properties.

Yes, I've several proprietory s/steel whip antennas that give
excellent results. But a question springs to mind. If a s/steel
antenna has slightly higher resistance, does that appreciably lower
its Q?

you mean it's bandwidth? probably, but why worry? it's not cut to
resonance, anyway. it's a resistor in an E field. Tx units can be run
with the telescoping verticle collapsed and still control the toy at
short ranges. i think the biggest prob would be front end overload
regardless of the antenna, which i'd try to deal with in an active
antenna setup which is well suited to short verticles, you just can't
let it blast the front end of one of those little RC Rxs.

i've used all kinds of different scraps of wire to get FM RXs going to
see if they work. how about those little pieces of scrap wire on RC
cars? they're no better than yours.
