Anyway it depends on how many degrees or decimals you moved the dish. On a 180cm moving the antenna less than 0.2 degrees there is no such change, from 0.3 degrees onwards you will get up to +- 1/1,5dB. Variable values about 0/1,0 dB is normal as the signal is not always steady. Anyway with large dishes it should be better to point the satellite with its exact position (with a 3.7m you can get a 3/4dB difference moving the antenna about 0.2 degrees !). But remember, always, each satellite moves itself around its position more times a day drawing a circle or a zigzag, moreover atmosphere does its job.</p></blockquote><p></p>
