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".
