  • Patent number: 4819006
    Abstract: A mount for connecting a satellite television antenna to a pipe mast. The mount includes a support assembly of a linear upright member and a cross member which are adapted for attachment to a peripheral portion of a parabolic dish antenna and a fitting attached to a lower end of the upright member which connects with a pipe mast so as to enable or prevent rotation of the support assembly with respect to the mast axis and to enable or prevent varying the angle of inclination of the upright member with respect to vertical.

  • Patent number: 4652890
    Abstract: A pair of facing channel members, or a short length tube saddle about the upper end of a vertical post and pivotably mounts a rocker assembly in the form of back to back channel bars. A bolt projects across the top of the facing channel members or tubes to locate the rocker bar and facing channel member or tube on the top of a vertically upstanding post. Right angle ball and socket mounts within end plates joining the rocker assembly back to back channel bars have projecting bolts received within paired frame tangs projecting outwardly from an open frame rigidly mounted to the dish antenna. The upper frame tang bears a slot to permit declination adjustment. The sweep, azimuth and latitude axes intersect each other to provide the lowest possible center of gravity for the antenna mount and minimize the moment arms for the members forming the same to thereby provide a highly rigid, heavy wind resistant support for the dish type antenna.

  • Patent number: 4628323
    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.
