Dan,

I'm using lots of segments - 10 times as many as the EZNEC Conservative 
Auto Segmentation.
Lossless Average Gain is 0.00dB
Convergence testing - doubling the number of segments makes no 
difference to any of the Gain or Loss figures.

I'm changing the wire dimensions, and watching the change in Average 
Gain and the change in Gain at various elevation angles both in FS and 
over Real High Accuracy earth. They're all slightly different - I was 
then quoting an average.
