Case Study 3
For a 4.5m earth station operating at 12.5 GHz calculate the loss of potential gain if the satellite is 0.125 degrees north and 0.1 degrees east of its nominal position. Assume the dish is pointed precisely at the nominal satellite position.
Solution 3
Satellite is 0.269 degrees off station.
At 12.5 GHz wavelength is 0.025m
(This has reduced the effective size of the dish from 4.5 m to approx 3.4 m ! )
