As for the program, I would like to order the full version of eznec,
but I can't possibly budget that in right now. Is there a similar
program available without the 20 segment limit? I am thinking I saw
one many months ago when I first tried playing with this one.

You could try 4nec2 at www.wyger.nl/usr/4nec2. If you are familiar with
EZnec, you should not have too much difficulties using 4nec2. However
both programs have their pros and contras
