[QUOTE="Trust, post: 902684, member: 181524"] This picture is not showing how the reflection at a Fibo 120 is , the subrefl. is more tilted forward and the lnb is between main reflc. and sub . I once messured my dish carefully and made a drawing with incoming and reflected signal lines . Dish was optimal pointed at 4.8º E with elevation of 30.7º for my location . Frontline of the main reflector leans back 3º so calculated offset angle 30.7 - 3 = 27.7º [/QUOTE]
