Abstract
The present invention relates to an antenna alignment meter which comprises a receiver for detecting a signal with predetermined characteristics and outputting data pertaining to the detection of the signal, and a controller responsive to the data from the receiver for controlling generation of an indicator that signal has been received. The meter can be used for aligning an antenna with a signal source. The meter is arranged to monitor signals received by the antenna and to provide an indication of correct alignment of the antenna with a desired signal source when a signal of a predetermined frequency, polarization, symbol rate and error correction is received.
Claims35
An antenna alignment meter comprising:
- a predetermined set of signal characteristics;
- a signal detector circuit for detecting a signal with said predetermined set of signal characteristics and outputting data pertaining to the detection of the signal;
- a connector for connecting the signal detector circuit to an antenna;
- and
- a controller responsive to the data from the detector circuit for controlling generation of an indicator that the signal has been detected;
- wherein the meter is configured to receive a single set of signal characteristics.
A method of aligning an antenna with a signal source, the method comprising:
- storing a predetermined set of signal characteristics;
- connecting the antenna to an antenna alignment meter;
- adjusting the orientation of the antenna until the antenna alignment meter indicates detection of a signal with said predetermined set of signal characteristics;
- and
- locking the antenna in position;
- wherein the meter is configured to receive a single set of signal characteristics.
An apparatus for aligning an antenna with a signal source, the apparatus being arranged to monitor signals received by the antenna and to provide an indication of correct alignment of the antenna with a desired signal source when a signal of a predetermined frequency polarization, symbol rate and error correction ratio is received.
An antenna alignment meter comprising:
- a controller for using predetermined signal characteristics to tune a receiver circuit to receive a signal with said predetermined signal characteristics and to output data pertaining to receipt of the signal;
- and
- a connector for connecting the receiver circuit to an antenna;
- wherein
- the controller is responsive to the data from the receiver circuit to control generation of an indicator that the signal has been received;
- wherein the meter is configured to receive a single set of signal characteristics.
A method of aligning an antenna with a signal source, the method comprising:
- connecting the antenna to an antenna alignment meter;
- tuning a receiver circuit of the antenna alignment meter to receive a signal having predetermined characteristics;
- then adjusting the orientation of the antenna until the antenna alignment meter indicates receipt of a signal with said predetermined signal characteristics;
- and
- locking the antenna in position;
- wherein the meter is configured to receive a single set of signal characteristics.
