Hi
I use a SAT FINDER app on my phone, available for Android and iphones, You tell it which satellite you want, its works out where you are via GPS, and works out the direction for you,Just point dish in that direction, If you turn on the camera you get arrows on screen so if you point it in the direction of satellite and you see clear sky you will get a good signal, if you see trees no wasting time even trying. I then use the signal test on sky box to fine tune, Using this I have never been quicker at setting up and finding a signal.
