Abstract
Abstract An antenna misalignment detector has two electrolytic transducers mounted on a mast carrying the antenna perpendicular to each other in the same horizontal plane. The antenna is mounted on a mast. The square root of the sum of the squares of the output from the transducers is generated and compared with a predetermined reference so that an alarm sounds when the antenna is misaligned along a vertical axis to the ground.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
75 words
An antenna misalignment detector comprising: a first electrolytic transducer mounted on a first axis, a second electrolytic transducer mounted on a second axis perpendicular to said first axis, means for setting a predetermined reference, means responsive to said first and second electrolytic transducers for generating the square root of the sum of the squares of the voltages of said transducers, and means for comparing said generated signal and said reference to detect an antenna misalignment.
Claim 2
Dependent Claim
75 words
An antenna misalignment detector comprising: a first electrolytic transducer mounted on a first axis, a second electrolytic transducer mounted on a second axis perpendicular to said first axis, means for setting a predetermined reference, means responsive to said first and second electrolytic transducers for generating the square root of the sum of the squares of the voltages of said transducers, and means for comparing said generated signal and said reference to detect an antenna misalignment.
Claim 3
Dependent Claim
112 words
An antenna misalignment detector comprising: an antenna, a first electrolytic transducer having an output signal proportional to its angle of tilt along its axis mounted on said antenna along a first axis, a second electrolytic transducer having an output signal proportional to its angle of tilt along its axis mounted on said antenna along a second axis perpendicular to said first axis, means responsive to the output signals from said first and second transducers for generating the square root of the sum of the squares of the signals of said transducers, means for setting a predetermined reference, and means for generating an alarm when said generated square root exceeds said set reference.
Claim 4
Dependent Claim
112 words
An antenna misalignment detector comprising: an antenna, a first electrolytic transducer having an output signal proportional to its angle of tilt along its axis mounted on said antenna along a first axis, a second electrolytic transducer having an output signal proportional to its angle of tilt along its axis mounted on said antenna along a second axis perpendicular to said first axis, means responsive to the output signals from said first and second transducers for generating the square root of the sum of the squares of the signals of said transducers, means for setting a predetermined reference, and means for generating an alarm when said generated square root exceeds said set reference.
Claim 5
Dependent Claim
22 words
The antenna misalignment detector claimed in claim 2 including a delay means to delay said alarm for a predetermined period of time.
