The tarnish doesn't do anything good. On a relative scale, silver is
250, copper 225, as is gold. Aluminum is 175. Stainless is about like
lead, 6 or 8. Plain carbon steel is 25. Thermal conductivity is
closely correlated with electrical conductativity for what that is
worth. Better at one is generally better at the other.

Richard...I'm telling you one of the worlds top antenna designers
lives here and I just happened to be lucky enough to get his help
setting up my radios. If he tells me tarnished silver is the best for
HF I take his word for it..If our goverment flys him all over the
earth to design develope and set up the best....that's good enough
reference for me.

I bet Larry could tell a few interesting stories on this subject.
Antenna designers are really in a world of their own. Back in the day I
remember a group of antenna engineers that were hired to keep a large
surveillence receiver antenna working. They would come down and crawl
inside the antenna case with a small metal tackle box. After a short
while you would hear some light banging here and there and then they
would come out and test it. The tackle box they carried had several
hammers in it they used to shape/tune the antenna with. In conversation
with them and from reading on the subject I learned that when it comes
to antenna design some of what you think should make sense, actually
doesn't. And sometimes stuff just works when intuitively you would think
it wouldn't.
