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. :)
