[QUOTE="a33, post: 1057158, member: 332642"] For a latitude of 58,2440* (that is very exact! :)) : Modified axis elevation = 31,18* Modified declination offset angle = 7,37* So total dish elevation due south = 23,81*, with an offset angle of 22,5 the dish face elevation should be at 1,31* NB Setting the total dish elevation by the dish face-method assumes the LNBfeedhorn really is in the correct offset angle to the dish. If you're not sure of that, you can check the actually used offset angle of your dish+arm by tuning the dish to a satellite with known elevation angle (see e.g. dishpointer.com), and measuring the dish face elevation. The difference is the used offset angle. (For that test, the polar axis must be turned in the zero (due south) position, of course!) Hope this helps getting your angles right! greetz, A33 [/QUOTE]
