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

摘要

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.
