Abstract:
A satellite antenna is provided, including a dish, a bracket, an extension rod and a receiver. The dish includes a reflective surface and a back surface. The bracket is connected to the back surface, wherein the bracket includes a pivot portion. The extension rod includes a first end and a second end, wherein the first end pivots on the pivot portion of the bracket, the extension rod is adapted to be rotated between a first orientation and a second orientation around a pivoting axis. The receiver is disposed on the second end of the extension rod and corresponds to the reflective surface, wherein the pivoting axis is located between the reflective surface and the receiver.
Abstract:
A fine adjustment mechanism includes a connecting unit and a fine-tuning bolt having a bolt shaft and a bolt head. The bolt shaft has a threaded section rotatably engaged with the connecting unit, a non-threaded section between the threaded section and the bolt head, and an annular protrusion projecting outwardly and radially from an outer surface of the non-threaded section and spaced apart from the bolt head. A retaining unit is molded over the fine-tuning bolt and covers the annular protrusion and portions of the non-threaded section which are proximate to two opposite annular end surfaces of the annular protrusion. The fine-tuning bolt is rotatable relative to the retaining unit. The connecting unit is movable along the threaded section when the fine-tuning bolt is rotated.
