ABSTRACT:
Antenna systems include adjustment mechanisms to adjust the position of dish antennas. The adjustment mechanism includes a clip, a bracket, and a cam mechanism. The clip is fixedly coupled to and projects outwardly from a mast. The bracket is pivotally coupled to the mast and is between the stationary clip and cam mechanism. The cam mechanism is pivotally coupled to the clip and positioned to rotate the bracket and the dish antenna as the cam mechanism rotates. The clip is made of a lightweight material to reduce the overall weight of the antenna system to enhance performance.
