Hi Ken,

I've done talks to ham clubs doing exactly that.  I modeled the 
antennas, then transferred data point by point to my spreadsheet and 
plotted the results in a form that made the differences easier to see.  
They are in the early pages of

You're welcome to borrow any of the slides, with credit given to me for 
the work.
