Dish Offset Angle

(Read 3276 times)

Polly Member ★★ Offline Posts: 2	Dec 10^th, 2016 at 1:48am Would some kind person be able to tell me the offset angle of an Ipstar antenna.� The horizontal diameter of the dish is about 1.2 m and my rough attempts so far suggest that the angle is more than 20�. Thanks.

If your antenna is anything like this:

Note that the rim does not appear flat. Therefore the calculation won't work.

If you are pointed at a known satellite find out the calculated elevation angle for your location using
https://www.satsig.net/maps/satellite-tv-dish-pointing-south-east-asia.htm

Then note or mark the elevation angle on the scale. At least that marked point of the scale will then have an exact meaning for you.� Set other elevations angles relative to that mark.
