ABSTRACT:
An alignment device and method for aligning an antenna with a satellite. The device includes a grooved cylindrical sleeve inserted into a ridged cylindrical sleeve, a raised azimuth indicator ring and a magnetic or digital compass mounted upon the grooved cylindrical sleeve, and a bubble level mounted on a capped cylindrical sleeve that fits over the grooved cylindrical sleeve. A known value of optimal azimuth alignment is offset from the North Magnetic Pole so that a reference and alignment mark may be placed on the antenna mounting pole. This alignment device and method eliminate the need for two technicians and eliminate the need for a signal strength measuring device.
