ABSTRACT:
A stove pipe elbow connection formed by using two pipes cut at 45 degrees angles and connected by flanges rotatable on each other provides elevation adjustment for a dish antenna between zero degrees and 90 degrees, with the base pipe projecting upwardly perpendicular to the earth surface. The base pipe is rotated about its axis until the flange connected projecting pipe points north and that assembly fixed. A two tube assembly having an inner tube slid over the angled projecting pipe and an outer tube fixed to the inner tube but having its axis at an angle of approximately 12 degrees thereto for correcting for maximum declination supports the antenna which rotates about the axis of the inclined outer pipe to adjust for declination. The antenna is bolted in place after the proper declination angle is reached and further rotation of the antenna about the axis of the pipe projecting causes the antenna to sweep across all of the satellites in the geosynchronous orbit sector bearing such satellites.
