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. Jim |
