I think simple, repeatable and accurate are a difficult triad. What
you are talking about is an accurate Field Intensity Meter (FIM) and
getting stable calibrations with home constructed equipment is not
going to be easy - let along easy to duplicate. The closest solution
is to use standard antennas (not simple whips) and calibrate them
against broadcast signals at known locations and known field strengths.
This will still require separate antennas for 160 and 630 meters and
separate calibration sources on the appropriate ends of the standard
broadcast band (due to the antennas).
