Mobile satellite receiving antenna especially for recreation vehicle

Claim 2

A vehicle mounted reflector dish antenna assembly for reception of microwave signals from a geosynchronous satellite, comprising: first means including a generally cylindrical collar having a top circumference shape substantially matching the peripheral circumference and shape of said reflector dish, said collar being contoured along its bottom edge to conform to the shape of said vehicle roof; second means for controlling the azimuth angle of the boresite of said reflector dish; third means for controlling the elevation angle of said reflector dish boresite toward said satellite and for folding said reflector into a downward-facing position against said collar top shape to form an enclosure during transport of said vehicle.

Claim 3

The combination according to claim 1 in which said second means includes a turntable within the interior of said collar and mounted over a bearing, said bearing being supported with respect to structure associated with said collar.

Claim 4

The combination according to claim 2 in which said second means further includes a gear surface coaxial and radially outward from said bearing, said gear surface being supported with respect to structure associated with said collar, and a reduction geared drive motor mounted on said turntable and having an output pinion gear engaging said gear surface to effect azimuth positioning of said turntable.

Claim 5

The combination set forth in claim 3 in which said structure associated with said collar includes a support plate within the interior of said collar, said support plate being attached to the interior surface of said collar.

Claim 6

The combination set forth in claim 2 in which hinge means are provided at said lower edge of said reflector to hinge said reflector dish to an adjacent point along the perimeter of said turntable, said lower edge of said reflector being identified when said reflector dish is in an operating position.

Claim 7

The combination according to claim 5 in which a linear actuator is provided and is operative between a point adjacent said reflector dish lower edge and a substantially diametrically opposite point adjacent the perimeter of said turntable.

Claim 8

The combination according to claim 1 further comprising a load distributing sheet affixed to said collar bottom edge, said load distributing sheet being shaped to be in substantial contact with said vehicle roof over at least a portion of the area of said roof beneath said collar, thereby to distribute the weight of said antenna assembly over a substantial area of said vehicle roof.

Claim 9

A vehicle mounted parabolic reflector dish antenna assembly for reception of microwave signals from a geosynchronous satellite, comprising: first means including a generally cylindrical collar having a top circumference shape substantially matching the peripheral circumference and shape of said reflector dish, said collar being contoured along its bottom edge to conform to the shape of said vehicle roof; second means including a load distributing sheet affixed to said collar bottom edge, said load distributing sheet being contoured to be in substantial contact with said vehicle roof over at least a portion of the area of said roof beneath said collar, thereby to distribute the weight of said antenna assembly over a substantial area of said vehicle roof; third means for selectively controlling the azimuth angle of the boresite of said reflector dish; fourth means for selectively controlling the elevation angle of said reflector dish boresite and for folding said reflector dish downward to a position concave downward over the top of said collar to form an enclosure for transport; fifth means comprising an antenna feed and means for locating said feed substantially at the focus of said parabolic reflector dish, said fifth means including a feed support and extending from said feed and hinged to a lower edge of said reflector, said rod extending upward at an angle when said reflector dish is in an operating position; and sixth means consisting of a flexible dielectric cable extending from a point in the concave surface of said reflector dish to said feed.

Claim 10

A vehicle mounted parabolic reflector dish antenna assembly for reception of microwave signals from a geosynchronous satellite, comprising: first means including a generally cylindrical collar having a top circumference shape substantially matching the peripheral circumference and shape of said reflector dish, said collar being contoured along its bottom edge to conform to the shape of said vehicle roof; second means including a load distributing sheet affixed to said collar bottom edge, said load distributing sheet being contoured to be in substantial contact with said vehicle roof over at least a portion of the area of said roof beneath said collar, thereby to distribute the weight of said antenna assembly over a substantial area of said vehicle roof; third means for selectively controlling the azimuth angle of the boresite of said reflector dish; fourth means for selectively controlling the elevation angle of said reflector dish boresite and for folding said reflector dish downward to a position concave downward over the top of said collar to form an enclosure for transport; fifth means comprising an antenna feed and means for locating said feed substantially at the focus of said parabolic reflector dish, said fifth means including a feed support and extending from said feed and hinged to a lower edge of said reflector, said rod extending upward at an angle when said reflector dish is in an operating position; and sixth means consisting of a flexible dielectric cable extending from a point in the concave surface of said reflector dish to said feed.

Claim 11

The combination according to claim 8 in which said third means includes a turntable within the interior of said collar and mounted over a bearing, said bearing being supported with respect to structure associated with said collar.

Claim 12

The combination according to claim 8 in which said third means further includes a gear surface coaxial and radially outward from of said bearing, said gear surface being supported with respect to structure associated with said collar, and a reduction geared drive motor mounted on said turntable and having an output prior gear engaging said gear surface to effect azimuth positioning of said turntable.
