FIELD: study of Earth's crust, search for mineral resources, prediction of earthquakes. SUBSTANCE: antennas are located under ground with conductivity not higher than 2•10-4cm/m and grounding systems are laid in ground with conductivity not less than 10-3cm/m. Registration of electromagnetic fields formed by emitting system of complex makes it feasible to study and to monitor Earth's crust, to search for mineral resources and to predict development of tectonic activity resulting in earthquakes. EFFECT: widened functional capabilities. 2 dwg
