Abstract:

EXPERIMENTAL MODEL OF AN ANTENNA SYSTEM NO MORE THAN 100 FEET HIGH FOR THE FREQUENCY RANGE 27 TO 60 KHz having a radiated power of 250 watts and a design goal of 300 watts. The input power is 50 kilowatts. A radiated power of 362 watts was achieved and some modifications and development were required to contain the voltages developed at 50 kilowatts of input power. The system is voltage limited somewhere above this power level depending upon the efficiency andor bandwidth-efficiency product of the system is approximately 0.85 cycles at the lowest frequency of 27 kHz and increases as the 3.8 power of the frequency ratio. It is shown that the system can be operated at 100 kilowatts input, 250 watts radiated, 377 cycles bandwidth at a frequency of 27 kHz. Author
