The dish elevation angle from the tool at Sadoun is 41 but the sat elevation is 56. Is there a difference? I have set up several dishes over time using the old hunt & seek method and never had a problem but for some reason I just can't get a signal. Tried from elevations 35 to 56. And the pole is vertical . Probably I have the LNB attached incorrectly. It is attached in a maner when looking at the dish diretly the cable is verticaly attached and the writing on the LNB is perfectly horizontal. I am replacing my old 18" dish. If I remove the LNB (old DirectTv)from that dish, will it work on this dish? Just to verify that I don't have a dead LNB. Any suggestions are welcomed. |
The elevation of the satellite is in fact 56. However with a
motorized system you don't use the elevation of a satellite for anything.
The dish elevation is basically a way to obtain your declination. It is basically the offset angle of your motor shaft (45 deg in your case) minus your declination (either 4.2 or 4.8 in your case). So basically the 41 thing you are reading is 45-4 approximately.
You didn't mention motor elevation above. Actually what you have is a motor elevation, which should be approximately 60 degrees (ie 90 minus your latitude), and to see the satellite you have to look down from that by your 4 degree declination, ie 60-4 = 56, ie the actual elevation of the satellite.
Hope that explains it. And for once I didn't get off track into "modified declination".
