Thanks for the reply and comments.

I have been enjoying my time playing around with the program. I have
notice that an antenna cut, trimmed and tuned at one location often
has a different dip in another.

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.

Thanks,

EZNEC-ARRL, a type of EZNEC v. 3.0, is included with the 20th Edition of
the ARRL Antenna Book. It has a 500 segment limit when analyzing any of
the several hundred EZNEC models included with the Antenna Book. You can
modify any of those models and retain the 500 segment limit. However, if
you save a modified model and open it again, the program will revert to
the 20 segments of the demo version, since the saved file isn't one of
the special ARRL files which relieve the segment limit. (Incidentally,
all those several hundred models are recognized by standard EZNEC
programs as ordinary EZNEC files, for those of you who have the standard
program.)

There are several other programs available which have higher segment
limits that are free. A web search and/or recommendations from other
people should lead you to some of them. NEC-2 itself is free and
available on the web, although you'll probably find it relatively
difficult to use.
