[TowerTalk] copper tank coils

[Jim Lux]

Silver plating is usually very thin, and doesn’t have a huge effect on the RF resistance.  One advantage is that silver oxide is conductive, copper oxide is lossy. Also, if you have a moving contact - silver is MUCH better than copper in terms of staying low resistance.

Interesting!
It would also be great to see data comparing:
silver plated copper
copper
oxidized copper
