The majority of domestic fixed elliptical dishes ( 28E ) that I see on people's houses always look horizontal with the LNB rotated. It is my understanding that elliptical or diamond shaped dishes have better side-lobe discrimination along their widest axis and that if the axis is orientated along the orbit, interference from the adjacent satellites will be minimised. Wouldn't this give a better BER ? With that in mind, why is the lnb not put in the 6 O'clock position and then
the whole dish rotated for the desired skew angle ? I know that some Sky dishes have an elliptical feed-horn lnb but I still don't understand why the dish isn't rotated like a motorised one would be.
