Relativistic runaway electron avalanches (RREAs) developing in electrified clouds produce gamma radiation which could be observed both on the ground surface and on near-Earth orbit. Radio emission of RREAs is a much less studied manifestation of the avalanche process. Meanwhile, VHF-radiation can be used as an additional source of information on conditions of the RREA development. We present the method of calculating the VHF signal produced by RREAs using Monte-Carlo simulation with GEANT4. We show that VHF radiation produced by runaway electrons has a maximum at frequency range 0.1--1 MHz, the amplitude is below the background noise.
