Antenna pointing aid
View Patent ↗A satellite system 10 includes an outdoor unit that has an LNB 24 . The antenna of the outdoor unit is aligned using a microwave energy-absorbing cap. The microwave-absorbing cap has microwave-absorbing material therein or thereon. A signal strength meter is used to measure the signal strength with the cap on so that the signal strength meter is less likely to be saturated during the alignment process.
1. A method of aligning an outdoor antenna comprising:
placing a cap having a base wall and a side wall extending from and affixed to the base wall on a low noise block so that microwave-absorbing material on the base wall is positioned adjacent to a cover of the low noise block and the side wall positions the cap relative to the cover of the low noise block;
absorbing microwave energy with the microwave-absorbing material on the base wall of the cap;
thereafter, determining a signal strength; and
orienting the outdoor antenna in a direction corresponding to a maximum signal strength.
2. A method as recited in claim 1 wherein the cap comprises a microwave-absorbing coating disposed on an exterior surface of the base wall.
3. A method as recited in claim 1 wherein the cap material comprises a microwave-absorbing coating disposed on an interior surface of the base wall.
4. A method as recited in claim 1 wherein the cap material comprises a microwave-absorbing plug disposed within the cap.
