A reflector-type microwave antenna having a paraboloidal reflector having a focal point and a feed horn located at the focal point. The feed horn is adapted to launch microwave signals onto the reflector and to receive microwave reflectors from the reflector. The reflector is mounted onto a surface by a mounting assembly comprising a mounting pipe in a fixed location relative to the mounting surface, a mounting cylinder rotatably affixed to the mounting pipe, and a mounting collar affixed to the mounting cylinder. A mounting plate is affixed to both the mounting collar and to the reflector such that a movement of the mounting collar causes the reflector to move, as well. The mounting assembly also has an azimuth coarse adjuster which engages the mounting cylinder such that the mounting cylinder may be rotated in azimuth relative to the mounting pipe. Once the mounting cylinder is in position, a locking mechanism is utilized to lock the mounting cylinder in position. An azimuth fine adjuster is also included and is rotatably engaged to the mounting collar, such that the azimuth fine adjuster may rotate in azimuth the mounting collar relative to the mounting cylinder. Once the azimuth fine adjuster has moved the mounting collar into the correct position, an azimuth fine locking mechanism locks the mounting collar in a position relative to the mounting cylinder without disturbing the azimuth fine adjuster. A similar construction is also provided for positioning in elevation.
