This antenna, which stretches approximately 2 miles in a north/south direction, has a beamwidth which covers nearly horizon to horizon in the east/west direction. The beam is aligned along a great circle, overlapping with the beams of the other two transmitter sites. In the north/south direction however, the beamwidth is only .02 degrees wide. That's in the far field, which begins at about 15,000 Km ! Most satellites pass through the beam in its near field, and spend about 0.5 seconds illuminated by the beam. The transmitter sends out a constant carrier 24 hours a day, and is neither pulsed nor modulated in any fashion. The site consumes about 1,000,000 KWH per month to generate one of the highest power ERP signals on earth, 6.3 billion watts ! When the moon passes through the antenna's beam, the return echo can be heard on earth with only a dipole antenna attached to a receiver. The Kickapoo signal has now travelled over 37 light years into space since being switched on in 1958.
