[Lowfer] Skin Depth at 185.300 Khz

Tue, 26 Nov 2002 22:02:26 -0500

Hello Gary,

Thanks for that piece of info.
Looks like 1 skin depth is about .006"

Should work out fine for what I have in mind.

A direct cut-n-paste from our friend G4FGQ in the UK

"Copper tube may be used for large diameter conductors. Provided wall
thickness
of tubes exceeds 5 times skin depth the results obtained by this program
will
will remain unaffected.  Skin depth in copper is 2.1/Sqrt(F) millimetres, or
0.082/Sqrt(F) inches, where F is frequency in kilo-hertz."
