Mal,

the conductivity of silver is better than that of copper. But the differen=
ce is marginal, the main advantage is that silver will not oxidate as much=
 as copper (metal oxides are rather poor conductors). That is why silver=
 plating makes sense, in particular on very high frequencies (where skin=
 depth is small, but solid silver wire does not (apart from the fact that=
 is will break very easy).
However, the conductivity of gold is worse than that of silver and copper,=
 I don't think that there is any good reason to use gold plated antennas=
 (maybe except for vanity).

Mike
Silver is ideal and better than copper but in California and possibly Texa=
s
they prefer GOLD, listen to those big W6 and W5 signals. I think W6AM had=
 a
gold plated rhombic around the mid 50's. The heyday of amateur radio befor=
e
the appliance operator appeared.
Nice to hear from you
