ABSTRACT:
An orientation adjusting apparatus includes a support base plate set rotatable relative to a mast about a first vertical axis. An azimuth bracket is rotatable relative to the top plate of support base plate set about a second vertical axis. An elevation bracket is rotatable relative to an elevation fine tune bracket about a first horizontal axis. The elevation fine tune bracket is rotatable relative to the azimuth bracket about a second horizontal axis. An azimuth angle fine tuning unit is operable to rotate the azimuth bracket relative to the top plate of support base plate set about the second vertical axis. An elevation angle fine tuning unit is operable to rotate the elevation fine tune bracket relative to the azimuth bracket about the second horizontal axis.
