Your thoughts on sweep frequency for impedance measurement is very
interesting. If I could figure out a way to build the "sensors" I'd
probably build a sweep system for 2 meters.

The ARRL handbooks of yore have several designs. Google "monimatch".


Although I could handle
building a sweep frequency generator, I wouldnt know how to convert the
"incident and reflected" to an impedance.

Software would do that.

No it wouldn't, unless you could figure out some way to get vector magnitude
and phase from the two channels.


I suspect that, if sweep frequency impedance measurements was simple
enough for Me to do, someone would already have done it and published in
one
of the HAM magazines.

Perhaps not the ham magazines; I know I've written at least three articles
in Kitplanes magazine as to how to do it for aircraft antenna VSWR.
