[TowerTalk] Loading Coils

[David Gilbert]

Yes ... that.

Nickle has about 4 times worse electrical conductivity compared to 
copper, and the skin depth at 30 MHz is about 20 times thinner (about 12 
microns for copper versus about 0.65 for nickle).  ChatGPT tells me that 
standard nickle plating is roughly 5 to 10 microns thick , and that even 
low cost nickel plating is typically 1 to 2 microns thick.

The math agrees with you.

I wonder if anyone has made measured comparison of his coils versus a 
similar copper one.
