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

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