Reg:

Great idea for a program but, I don't like the name.

Would you consider renaming it:
SWR-****ING-MATCH.exe

This program models the behaviour of a transmission line plus
antenna.
The line impedance can have any Zo. The antenna feedpoint impedance
can be any value of R+jX. Line length can be any fraction and
number
of wavelengths. Line overall attenuation can be any value of dBs.

There is an SWR meter located at each end of the line. The meters
also
indicate the reflection coefficients at the locations. Meter Zo can
be set equal to line Zo or to the standard 50 ohms.

Line input impedance can be observed to change versus line length in
wave-lengths, line attenuation and antenna impedance. The
transforming
action of the line can be demonstrated. The smaller SWR and
reflection
coefficient at the transmitter end of the line can be seen. The
exact
increase in loss due to standing waves on the line is calculated.

The program can be used in practical applications and also for
educational purposes. It is hoped it may prevent the outbreaks in
violence which frequently occur in newsgroups about the meanings of
SWR and the notions of reflected power.

Download program SWRARGUE from website below in a few seconds. File
size = 41 Kbytes. Run immediately. No unzipping inconvenience.
