The parameters of radio radiation generated in an air medium by an electron beam from a RELUS 1 small electron accelerator (Radiation Acceleration Center, MIFI) were studied theoretically and experimentally. Theoretical models for the generation of electromagnetic fields over the frequency range 10-3000 MHz induced by an electron beam were developed and studied. Electromagnetic fields from a beam of electrons were recorded over the frequency ranges 140-160 and 2794-2804. The discrepancy between theo retical estimates and recorded values was less than 50%.
