A dish antenna adjustment method is performed as follows. A dish antenna angle adjustment apparatus is provided; the dish antenna angle adjustment apparatus having a base member, a first rotation member and a second rotation member. The first rotation member is pivotally connected to the second rotation member, and rotates by a first rotation angle relative to the second rotation member. The second rotation member is pivotally connected to the base member, and rotates by a second rotation angle relative to the base member. A first rotating angle adjustment mechanism is connected to the angle adjustment apparatus of the dish antenna, e.g., the first rotating angle adjustment mechanism connects the first rotation member and the second rotation member. The first rotating angle adjustment mechanism adjusts the first rotation angle between the first and second rotation members. The first rotating angle adjustment mechanism is detached from the angle adjustment apparatus, and the detached first rotating angle adjustment mechanism can be used for adjustment of another dish antenna.
