ABSTRACT The measurement of the intensity of the electromagnetic fields (EMF) in working rooms is connected with many difficulties: EMFs are very intensive, the workplaces are near to grounding metal masses, in the room there are reflected surfaces, etc. There are no apparatuses (serial production) with the necessary characteristics about the purposes for such measurements. The attempt to create and construct devices for measuring the EMFs in the frequency range below 30 MHz is described in the report and also the questions and problems which should be resolved in the future. We construct antennas for measuring 10.5-12 8. the intensities of the EMFs below 30 MHz with an accuracy
