[Amps] Silver Plating Tank Coil ??

[ToddRoberts2001 at aol.com]

Hi  All,
Thanks for the comments on Gold  plating a tank coil.
I think one thing that was overlooked is Gold plating is  usually extremely
thin, on the order of 1 or 2 microns, or 0.04 to 0.08  mil.
At HF frequencies the skin effect depth is orders of  magnitude
greater than this, perhaps 2 to 4 mils, so the RF current stays 99%  in the 
more 
conductive copper underneath the gold plating. The Gold plating  does indeed
protect the surface from tarnish, and would have an  almost
negligible effect on the RF resistance of the tank coil at HF  
frequencies.
