Abstract
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 ![[FORMULA]](img1.gif)
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.
