Somehow, and using Nec2, I seem not always able to get expected
impedance values when using the results produced by L.B. Cebik's stub
matching software at http://www.cebik.com/trans/ant-match.html

Does anybody know a source for (similar) stub matching software
(freeware or evaluation), so I can check where things go wrong ?

Thanks in advance,
Arie.
