The radiation parameters were determined at five test frequencies 14.7, 16.6, 19.8, 23.4, and 28.5 kHz, with the transmitting antenna operating in a dual or parallel east and west array configuration and in a single east array. The parameters were also determined for the antenna system operating in a single west array configuration for four frequencies 16.6, 19.8, 23.4, and 28.5 kHz. A test to determine the possible onset of corona losses was performed with the dual array operating at 14.7 kHz, 23.4 kHz, and 28.5 kHz test frequencies. The values for the radiation parameters as well as the results of the corona tests are reported and discussed herein, along with a detailed description of the experimental techniques and data reduction process.
