1. An adjustable antenna mount for attaching a directional antenna to a support, said antenna mount comprising:
- a post defining a first axis and having opposed ends including a mounting end and a free end,a base assembly rotatable around the first axis and connected to the free end of the post,means for coupling said base assembly to said post, said means for coupling including a first sleeve-and-bearing arrangement with a sleeve rotatably fit about a bearing surface;
an elevation adjustment assembly rotatably coupled to said base assembly by a second sleeve-and-bearing arrangement and rotatable around a second axis substantially perpendicular to said first axis;
an antenna vertical orientation adjustment assembly rotatable coupled to said elevation adjustment assembly by a third sleeve-and-bearing arrangement and capable of rotation around a third-axis which is substantially perpendicular to said second axis;
a tracking adjustment assembly rotatably coupled to said vertical orientation adjustment assembly and antenna frame means for coupling said tracking adjustment assembly to said directional antenna, said tracking adjustment assembly coupled to the vertical orientation adjustment assembly by a fourth sleeve-and-bearing arrangement; and
a sweep assembly coupled to said vertical orientation adjustment assembly, said sweep assembly having a means for rotating said tracking adjustment assembly around a fourth axis which is substantially perpendicular to said third axis, said tracking adjustment assembly having a means for adjusting the angle of said antenna frame means relative to said fourth axis.

Abstract
An antenna mount for aiming a parabolic antenna towards a geosynchronous satellite characterized by four, pivotal sub-assemblies, each of which is rotatable around its own axis. The mount can be quickly adjusted to point the antenna at a particular geosynchronous satellite, or may be caused to sweep across the satellite belt in a scanning manner. The antenna mount can be attached to a support post of virtually any orientation ranging from vertical to horizontal.

9. An adjustable antenna mount for attaching a directional antenna to a support, said antenna mount comprising,
a post defining a first axis and having opposed ends including a mounting end and a free end, a base assembly having an elongated first sleeve rotatably fit about a surface of said post to permit rotation of said base assembly about the first asis, said base assembly having a second sleeve fixed to one end of said first sleeve, an elevation adjustment assembly having a first bearing engagement member, said second sleeve of the base assembly rotatably fit about said first bearing engagement member of the elevation adjustment assembly for rotation of said elevation adjustment assembly about a second axis substantially perpendicular to said first axis, said elevation adjustment assembly having a third sleeve, a means for selectively adjusting the angle of said third sleeve relative to said first sleeve, a vertical orientation adjustment assembly having a second bearing engagement member rotatably fit within said third sleeve and capable of rotation about a third axis substantially perpendicular to said second axis, said vertical orientation adjustment assembly having a fourth sleeve, a tracking adjustment assembly having a third bearing engagement member rotatably fit within said fourth sleeve and capable of rotation about a fourth axis substantially perpendicular to said third axis, an antenna frame mounted to said tracking adjustment assembly, said tracking adjustment assembly having a means for adjusting the angle of said antenna frame relative to said fourth axis, and a sweep assembly coupling said vertical orientation adjustment assembly to said antenna frame, said sweep assembly having a means for rotating said tracking adjustment assembly about said fourth axis.
