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
