Abstract:
1. A system for positioning a dish antenna having a plurality of low noise block converters (LNB's) for the simultaneous reception of signals from a plurality of satellites in a direct broadcast satellite system comprising: an integrated receiver/decoder (IRD) for powering a first LNB corresponding to a first satellite and a second LNB corresponding to a second satellite, where said first and second LNB's and said first and second satellites correspond to the extreme limits of the satellites in the plurality of satellites, the IRD toggling the power to the first and second LNB's; a first peak detector for comparing a first sample signal from the first LNB to a first threshold value; a first peak indicator being activated upon the first sample signal meeting the first threshold value; a second peak detector for comparing a second sample signal from the second LNB to a second threshold value; a second peak indicator being activated upon the second sample signal meeting the second threshold value; a comparator for comparing the first and second peak sample signals; and a master lock indicator for indicating a master lock when said first and second peak sample signals are detected.
