Analysis of Propagation Conditions of ELF Radio Waves on the “Zeus”–Transbaikalia Path

We consider the results of measurements of the absolute values of horizontal electric and magnetic components of the electromagnetic field of the “Zeus” ELF radio facility at frequencies 33, 44, 82, and 188 Hz, carried out in Transbaikalia. Electromagnetic-field variations during 17 semidiurnal sessions (about 204 hours of synchronous records) are analyzed. The length of the “Zeus”–Transbaikalia path is approximately 4000 km.
