Hi,ppl I find it too diffecult to calculate the elevation angle for offset dish while with the prime focus dish it is very easy to calculate the elevation angle Is there a technical formula to convert elevation angle from prime foucus dish to offset dish ?

Best Regards
 
Can you catch some satellite with that dish? If yes than get maximum signal by changing elevation and than measure elevation angle of antenna. So, you know elevation of that particular satellite for your place, extract from that your measured angle and that will be antenna's offset angle.

Thanks Sleepy Hollow for your help regarding your question yes I receive this satellite Turksat 2A at 42 E with the prime foucus dish the elevation angle 60 degree But with the offset dish not easy to get the elevation angle because the offset dish is almost upright tilt to the horizontal level only a few degrees and not easy to get the elevation angle to receive the satellite signal but knowing the a fixed angle save time and a lot of work trying to adjust the dish to get the wright angle
 
You need the offset angle from the manufacturer.

thats what i thought but all suggestions were around 10 degrees out, study the link ive posted and it will make sense, (after a day or so)

You are right, but, there is no way how to calculate offset angle of the dish. If you know exact model of your antenna than you could find that angle in manual. You also can try to post some pictures here and, who knows, perhaps somebody can recognize the model. Is that really so difficult and time consuming to tune that antenna to one satellite? :-DOH2

my above post was not meant to prove anyone wrong, i was just trying to be helpful :-thumb1

This is how i did it, once calculated on a known satellite,away you go.
