Abstract
Abstract An automatic antenna alignment system for enabling maximum signal reception includes a storage circuit for storing the maximum energy developed by a receiver as a directional antenna is rotated through a first revolution and a comparator for comparing the signal stored during the first revolution with the signal developed by the receiver during a second antenna revolution such that when maximum signal reception occurs during the second revolution, the output of the comparator will trigger a switch and thereby stop the antenna in the direction of optimum alignment for maximum signal reception.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
144 words
Apparatus for aligning a directional antenna comprising means for rotating said antenna in azimuth, receiver means for receiving energy impinging upon said antenna as said antenna is rotated, first storage means for storing a first energy indicating the direction of maximum power during a first complete revolution, second storage means for storing a second energy indicating the direction of maximum power impinging upon said antenna during at least a portion of a second revolution, comparison means for comparing the maximum power of said first energy to the maximum power of said second energy, said comparison means controlling switch means, and timer and holding circuits responsive to said switch means for stopping said means for rotating when the direction of said first and second powers are aligned, whereby said antenna is aligned in the direction of maximum power of said first energy for optimum reception.
Claim 2
Dependent Claim
144 words
Apparatus for aligning a directional antenna comprising means for rotating said antenna in azimuth, receiver means for receiving energy impinging upon said antenna as said antenna is rotated, first storage means for storing a first energy indicating the direction of maximum power during a first complete revolution, second storage means for storing a second energy indicating the direction of maximum power impinging upon said antenna during at least a portion of a second revolution, comparison means for comparing the maximum power of said first energy to the maximum power of said second energy, said comparison means controlling switch means, and timer and holding circuits responsive to said switch means for stopping said means for rotating when the direction of said first and second powers are aligned, whereby said antenna is aligned in the direction of maximum power of said first energy for optimum reception.
Claim 3
Dependent Claim
35 words
The structure of claim 1 in which the maximum power of said second energy is substantially the same as the maximum power of said first energy, and said switch means includes a zero level switch.
Claim 4
Dependent Claim
17 words
