[K3CAL] Free Antenna Modelling Software

[Shawn Donley]

Steve,

See  http://k9vic.info/files/Antenna%20Modeling/EZNEC%20Primer.pdf  for your answer.

But also see the link below to an email exchange between a EZNEC user and the EZNEC author.  As I mentioned, it's mandatory to read the EZNEC product manual front to back and a good book on EZNEC lest it be used incorrectly and generate bad answers.

And this link probably provides more information on the G5RV than you ever wanted to know.  Written by a true antenna guru, L.B. Cebik, W4RNl (SK).

Have fun.

Shawn

But like any sophisticated simulation software, it's important to understand how to use it properly to avoid incorrect results.  There are books available and even on-line resources like:
