I don't have any problems using AO which your friend has!
Have you looked at W4RNL pages on the antenna modelling?
He may very well have all the data you need on that antenna.

Hi Art,
if you model this antenna (http://nw3z.contesting.com/20mon48'.htm) with
AO, you obtain the same results?
Thanks and 73

Probably,It all depends our much varience you would accept
before you said it was "wrong". As I said earlier W$RNL
has doine enough work on the OWA for you to determine
why you are going wrong and he uses the same programs
that you have!
