There is usually a chart at the back of the motor manual which gives you the correct DISH elevation setting according to the Motors Elevation !
ie
for me...... my motor elevation is set to 51.5 north which means my dish Elevation has to be set to 27.5 according to the chart i had !
this settings can be made prior to the installation along wiv the usuals set up ! if you follow the instructions correctly you should only have to align the dish on the moter to 1 reference satellite ! and this would be done by moving only the motor left or right on the pole cos the dish will be set to its position on the motor already wiv usuals !
Like glenviewjf said
Quotethrow up the dish and motor
and then you will have a reference point to work from !
i would use 13e or 28e as a reference point cos they're both pretty strong signals to find in the uk !
