Abstract
Abstract A method and device for aligning a satellite receiver antenna with a broadcast satellite is disclosed herein. The device includes a receiver for measuring a signal strength from the satellite and issuing commands based on the measurement, a receiver antenna capable of automatically changing its alignment, and a rough alignment indicator located remotely from the receiver for signalling when the antenna is pointed sufficiently toward the satellite allow the receiver to maximize the signal strength by aligning the antenna with the satellite via commands from the receiver. The method includes placing the receiver antenna on a stable surface, manually pointing the antenna in the direction of the satellite until an indicator signals that the antenna is preliminarily aligned, fixing the receiver antenna to the stable surface, and activating a device remote from the antenna to automatically perform final alignment of the antenna with the satellite.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
117 words
A device for aligning a receiver antenna with a satellite, said device comprising: a receiver that measures a signal strength value of a signal received from said satellite and issues commands based on said signal strength value; a receiver antenna in communication with said receiver for receiving said signal from said satellite, said receiver antenna being adapted for electronic alignment with said satellite in response to said commands issued by said receiver, the electronic alignment occurring without physical movement of the receiver antenna; and an indicator located in proximity to the receiver antenna, said indicator signalling when said receiver antenna is sufficiently aligned with said satellite to permit said antenna to electronically align itself with said satellite.
Claim 2
Independent Claim
117 words
