Sorry, it is not my day, I didn't see this answer neither. Ok, TKS, my
mistake, now I put 1/5 S/m = 0.2 ohms-m (free space simulation, 0,97 m
length, 10 segs) and similar results to bad resistivity but with 50 mm
wire diameter now (0,57). Do you trust in this results?, seems more
optimistics than IEEE paper.

Yes, I trust these results. If the IEEE paper agrees with your earlier
calculation, I suspect that the author made the same mistake you did.

Oops, I just took another look at your posting. You should put in 0.02,
not 0.2 ohm-m.

Oooops... Well... seems this it in not "our" day :) 5 S/m it is 0.2
ohm-m test data and calculations:

by the way: I do not use calculators, so much mistakes made my
fingers... I am happy since MathCad come to my life :D

IEEE author said to have made measurements. The really interesting
thing it is EZNEC seems to confirm the hipotesis.
