 I saw somewhere that, unless you have solid, not electro-plated, silver you 
gain nothing plating silver on copper. Electroplated silver have lower 
conductivity than OFHC copper.


Looks like polished copper is the way to go. I like the durability of Al 
though. Is polished and varnished copper the best?



Go figure,

##I did notice that stuff like  RG-303  with its silver plating, which is over 
the copper bonding..which is over the steel core..... on software, 
appears to flat line about 9.2 mhz and below... power wise.   My guess is, the  
skin depth is deep enough such that the current is now into the steel core. 
RG-400  doesnt have that issue,  nor does RG-142.   RG-304 also has a steel 
core..same issues. 

##  But what the heck do I know,.. I just experiment.  Besides,  copper tuning 
is cheap at any home depot or supply house.   Then I silver plate it
with the cool-amp goop...just so it looks nice.  Bare copper drives me nuts, I 
lose sleep over it, looks un finished to me. 

Later.... Jim   VE7RF
