Introduction:
There are a variety of programs available to the Radio Amateur that will calculate virtually every transmission line parameter that one may need. However, I have found the routines to be inconveniently scattered among many different programs. In addition, the programs usually require the data to be entered in serial form in order to obtain the calculated output. If another calculation is desired, all the data must be re-entered. As a result, I felt the need to create a spreadsheet style program where all input values are displayed and multiple “what-if” data changes may be implemented quickly with the click of the mouse.
Initially I used the spreadsheet to design Stub and Series Section Line Matches. Since then other utility functions were added that has enabled it to replace the Smith Chart, the pocket calculator, and the many computer programs for transmission line design applications.
