Its my understanding that the author of EZNEC hangs out in this group, I
wish he would put his 2 cents in also.

Sorry, I've been otherwise occupied lately.

Also, I don't generally comment in threads asking for software
recommendations except occasionally to answer a factual question or
correct the rare factually false statement, because the poster wants and
should get unbiased opinions from users rather than the invariably
biased opinions from developers and sellers.

As you can see from the responses, there are many choices, each with
advantages and disadvantages, and the same choice isn't best for
everyone. The only comment I'll make about EZNEC here is that anyone who
does purchase it and isn't completely satisfied will get a prompt and
full refund.

I do, however, believe very strongly in the power of computer modeling
in general, and will readily recommend that anyone interested in
learning more about antennas get some sort of modeling program.
