WHIP is a small calculation program for HF whips and wire antennas on cars,
shelters etc. It shows complex impedances as well as capacity and inductance values
for simple matching circuits that should be located directly at the feeding point.
WHIP is much simpler than EZNEC, MMANA, or 4NEC2, but offers the
advantage that the effects of parameter changes are visualized immediately. The
interactive functionality of the program enables you to "play" with the different
parameters. This feature can be a help on the way to understand the physical
laws of antennas and the transformation rules of complex impedances. The roots
of this program go back to 1982, when I made such calculations on a Casio programmable
calculator. In the end of 2008 I transformed it to a PC program, with some small
improvements over the years.
Below you can see some screenshot examples that give you an impression of the
program functions. Please observe that this program is part of my own attempts
to describe the reality, so I can not guarantee that it is free of errors.
You may download and use this program for free, and if you observe any points
that may be subjects to discuss, you are invited to mail your opinion.
If you think that there are too many curves... of course you can select and deselect
each output parameter separately...
... or show the impedances and transformation paths in R/jX graphics...
If you are lucky you discover some hidden functions I built in for
special purposes, try to find out...
