For those of you that would like to know more about EZNEC, the antenna modeling
software and missed my presentation Monday evening, Walter has recorded it and
here is the playback.

Holmes, K5WH.
EZNEC is a free download, just Google EZNEC. I have downloaded EZNEC Pro/ 2 V
6.0, there is a V 7.0 that does not want to down load right now. I know of
two minor faults in V 6.0. One feature missing allows you to work with an
impedance other than 50 Ohms. When you set an alternative value there in no
way to select it on the VSWR chart. Also, there is an option to change the
frequency selected and have the values of the wires change accordingly. Neither
are a major flaw and will probably be fixed in V7.0.
I encourage you to play with various versions of a wire (s) and freed point.
You will learn about antennas. At the ARRL you should search for modeling and
you will find a zip file of EZNEC files. There are also .YAG files. I don’t
know about them.
If you have a question, would like to talk about more complicated antennas or
have found something interesting, please contact me.
