[QUOTE="anton, post: 29313, member: 176045"] I am planning to put a pole for my future big dish in my garden and the positioning is going to be critical as I need to place it so that it sees betwen two buildings and also relative to some real fruitful appletrees which may or may not need to be cut down in the process. To get the angle right I wonder what is the position of the satellite above earth. While I learned they hang above in the height of 36 000 km and above equator (that ‘s for latitude), what about their longitudinal position? Is this calculated from zero meridian (Greenwich) ? I also found an Az-El calculator which gave me azimuth angle of 192 for my position but I am not sure what to do with it? When I installed my first (smaller dish) I just took a bearing with compass for south and then twisted the dish 28 degrees east of that. The compass was confused for a while, being close to the METAL dish but somehow I managed to get a perfect picture after only a couple of minutes of gentle skewing. But now I think it might have been a fluke and anyway the exact positioning then was nowhere near as critical as it is going to be this time. So please anybody: East of what? and How am I to use the output from the AzEl calculator? [/QUOTE]
