Abstract : An evaluation was made of an earth probe antenna formed by connecting receiver input terminals to electrodes in the ground 343 meters apart. Reception of coherence and sferic signals on this antenna at frequencies below 50 kc was compared with that received on horizontal overhead antennas. Although the voltage output from the overhead antennas was consistently higher than the signal taken from the ground probe antenna, the higher signal to noise ratio of the ground probe antenna indicated its potential use in the VLF range.
