I just ran across this on eBay.

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=1374780132

Sure looks handy. By that I mean simple & straightforward.

Does anyone know of a S/W based version of this? Or where I might find the formulas it uses so I might model this using excel? Unless I'm missing something I'm not seeing anything this straightforward in the ARRL antenna handbook.

I have an Autek RF-1 Antenna analyzer and it sure would be nice if I could input found (and 'what if') values of L & C to determine resonant freq.

Thanks

Maybe you would like MMANA even better than a slide rule!  This is a good antenna analysis software for the extremely reasonable price of $0.  Download it here:

Like all software from this author, it is well written and truly free (not shareware, no nag screens, etc).  He also has software for SSTV, RTTY, and others.

It shouldn't be too hard to just plug the standard formulas into a spreadsheet. Just use the formulas from the book, set up you input data fields & have at it.

However, if I had seen it the price would have been over $9.95!
