Antenna alignment indicator system for satellite receiver

摘要

An apparatus for aligning an antenna, for example an antenna of home satellite receiver system, includes means for detecting a received signal strength of a signal received at the antenna. Coupled to the detecting means are means for generating a display signal indicative of the received signal strength. The means for generating are configured to provide a first display signal when the received signal strength is in first state and to provide a second display signal when the received signal strength is in second state. Coupled to the means for generating the display signal are means for displaying the display signal. The means for displaying are capable of responding to both the first display signal and the second display signal. The first display signal may be a signal having a frequency proportional to the received signal strength. The second display signal may be a signal having a frequency proportional to the inverse of a difference between maximum received signal strength and a current received signal strength, thus providing a measure of antenna alignment error.
