During the austral summer of the 25th Indian Scientific Expedition to Antarctica (2005-06), an indigenously fabricated passive antenna system was installed at Maitri, Antarctica to monitor the potential gradient continuously. The potential gradient observed by the passive antenna is compared with the observations taken by the conventional field mill. The signature of the potential gradient is further verified using the global lightning activity obtained by the LIS instrument onboard TRMM satellite. The present work deals with the validation of the data and to some extent to establish the merits and demerits of the system. For this purpose we have selected data for a fortnight from the data set of April 2006. The reason for selecting this period was that the global thunderstorm activity is expected to be at its lowest during the austral summer. Southern Hemisphere summer does not produce sufficient number of severe thunderstorm activity. During the month of April the Sun is over the equator and the thunderstorm activity is expected to be more than that of the austral summer months.
