4.5M Satellite Antennas

Description

The 4.5 meter earth station has a standard elevation-over-azimuth mount, engineered to provide continuous satellite arc coverage from any location in the contiguous United States. Pointing of the antenna is rapid and accurate. Complete 360′ azimuth coverage eliminates required alignment of the foundation to a specific heading, eliminating the possibility of installation errors associated with foundation center lines.
