I just assumed.....why should I spend all that 'quality time' on a modeling
program

Just going on what I have done, it is really interesting to model antennas
that I have have actually built, and see if the results agree with the model.
Mostly they do.
I have found that it is easier to model an antipacited design, and go through
the various iterations to see how it pans out.
It has been 4 years since I have built an antenna without modeling first
Antennas are fun, and cheap, at least wire is cheap
