Some aspects of the Large Current Radiator construction for subsurface sounding applications at the depths of up to some hundred meters are considered. The antenna has to operate in a wide frequency band and transmit power effectively under the ground surface. It is shown that the antenna designed as a small horizontal magnetic loop with specific shape located close to the earth surface transmits power quite effectively when one of the wires, situated close the surface, is flat and the second is shielded by an envelope with certain electrical constants.
