Traceable electric and magnetic field calibrations of radiation monitors for amateur radio inside a parallel plate transmission line up to 30 MHz

Abstract. In many countries the electromagnetic field strength in the proximity of licensed amateur radio stations is limited to ensure public safety. If the station antenna(s) and/or the environmental situation are complex, only measurement results are acceptable as proof, and proper calibration of the field strength meters ("radiation monitors") is mandatory. A system and a procedure are described here, enabling calibration of such "radiation monitors" at a high quality level and traceable to the SI units, but with low-budget amateur equipment.
