Abstract: An antenna mast system (100) comprising a base (102), a plurality of selectively securable modular mast bodies (104), and an antenna mount (106). The base is aligned to a datum and each part of the system is aligned to the base to provide an accurate and repeatable antenna positioning system. The antenna mounting apparatus (106) comprises an antenna mount (138), an intermediate member (158) pivotally attached to the antenna mount to pivot about a first axis (160), an antenna bracket (162) pivotally attached to the intermediate member (158) to pivot about a second axis (164) substantially parallel to the first axis. A control system is used to control the actuation of the system.
