Benefits of technology
The present invention provides a dish bracket and elevation bracket for a dish antenna that can be easily strengthened and adjusted independently. The fold wings are symmetrically rotated and designed to prevent rough movement when re-rotated. The invention solves the problem of unsymmetrical rotating so that exact adjustment of a rotation angle and an elevation angle can be accomplished. The dish bracket also includes a related peripheral device for installation as required by a multi-beam reflection antenna.
Problems solved by technology
In addition, because the receiver is sensitive to the position of the DBSs and has to be able to endure 60 m / s of wind pressure, the receiver is more difficult to manufacture.
This causes the symmetry of the fold wings to be weak.
Thus, the fold wings cannot be symmetrically rotated with the dish 10, which results in a poor receiving precision.
The changed shapes of the fold wings may further result in rough rotating when the next adjustment is made, which makes it more difficult to adjust the position of the clamp 31 for an accurate elevation angle.

Embodiment Construction
[0029]FIG. 2 illustrates a perspective view of the invention for the rotation apparatus of a dish antenna. The apparatus comprises a dish 40, a dish bracket 50, an elevation bracket 60, a multi-switch bracket 70, an arm 80 and a clamp 31. The clamp 31 further comprises a mast 32, which has one end coupled to a pedestal 33. The multi-switch bracket 70 is used for holding a multi-switch device 71. The arm 80 is used for connecting a Y-adapter 81 to support at least one LNBF 82.
[0030]FIG. 3 and FIG. 4 illustrate a perspective view and a top view, respectively, of the embodiment of FIG. 2 for an elevation bracket 60 and a dish bracket 50. As shown in FIG. 3, the dish bracket 50 includes two circular grooves 51and, which form concentric circular grooves around a circular axle center 52. The elevation bracket 60 further comprises a pair of wings 601 and a bottom portion 602, which are formed as an organic whole. The two wings 601 are substantially parallel to each other and are connected ...

A rotation apparatus for a dish antenna provides a system for easily adjusting the dish antenna to a precise receiving position. The rotation apparatus includes a dish bracket which is fixed to the back of the dish antenna. The dish bracket includes a plurality of circular grooves and a concentric axle center. An elevation bracket includes a pair of wings and a bottom. The wings are parallel, and the bottom is perpendicular to the wings. Each wing pivots about an axle which passes through a first portion of each wing. A second portion of each wing includes a guide groove to adjust a elevation angle of the dish. The bottom includes a central axle hole and a plurality of holes. The central axle hole is coupled to the concentric axle center. After the dish is rotated to a selected position, the plurality of holes are secured to the circular grooves using a plurality of screws.
Description
REFERENCE TO RELATED APPLICATION[0001]The present application claims priority from Taiwan Patent Application No. 089209347, entitled “Dish Antenna Rotation Apparatus,” filed on May 24, 2000.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The invention provides a dish antenna rotation apparatus. The apparatus comprises a dish bracket and an elevation bracket. The dish bracket can more easily and exactly adjust a rotation angle. The elevation bracket can more easily and exactly adjust an elevation angle.[0004]2. Description of the Related Art[0005]A synchronous direct broadcast satellite (DBS) is a one point to multi-points communication system in which signals from the DBS can be received by a small antenna and a tuner device. Generally speaking, the DBS can receive signals from a specific earth surface transmitter, and then the DBS can send the signals to multiple earth surface receivers. After an earth surface receiver collects the signals of the DBS into a dish ref...
