Last year I found that W6QHS (now W6NL) Lotus spreadsheet and converted
it to Excel 2003 XLS format. His spreadsheet is used to determine the
survivability of a tapered element. It is not an RF design tool. Anyone
can download a copy of ELEMENTS.XLS from here:

I added a number of worksheets to create this new workbook. The first
sheet contains the formulas / calculations. The second is a mechanical
layout of the 40m Telrex I was experimenting with. I added two more
pairs of worksheets to I could quickly jump among different design
parameters. The final worksheet contains some information I found
regarding Frank's antennas at W3LPL and I saved it for reference.
Also, for those who don't have a "charting VSWR meter", there is also a
workbook that lets you input VSWR values and it will create a chart that
you can print out. That file is "VSWR charting tool - Rev 3".

I have used the W6QHS algorithm with excellent results. To make
calculations easier, there is an old spread spreadsheet someplace on the
internet which can be converted to Excel.

I'd like some advice on software, scripts or ways to convert single
diameter tubinng into tapered element, and back.
I've been advised to try ON4UN's software, but I could not run it on
windows7.
Thanks,
