[Elecraft] 80 Meter loop question

Modeling is also very educational. You may learn that a proposed antenna is
inferior to a simple dipole. I agree that EZNEC is easy to use and
reasonably accurate.

I agree, I use ver 5 also.  Easier to move stuff around.  Once you try
modelling you will find it consumes an incredible amount of your time, but
FUN.

It's pretty easy to model with NEC, which yields this data in the form a 
plot of VSWR vs frequency with data points as closely spaced as you 
choose. Move the cursor to each data point and you'll see complex Z.

I've learned a lot from using NEC, not only to design antennas but also 
to learn from the results of the model, changing variables, etc.

4NEC2 is free and quite powerful. I use EZNEC 5.0 because I find the UI 
easier to relate to, but it costs money. :)
