Gamma-ray bursts, if they are generated by relativistic strongly magnetized winds, may be accompanied by very short pulses of low-frequency radio emission. The bulk of this emission is expected to be at the frequencies of MHz and cannot be observed. However, the high-frequency tail of the low-frequency radio emission may reach a few tens of MHz and be detected, especially if the strength of the magnetic field of the wind is extremely high.
