You don't need to aim the dish anywhere, as your receiver does it for you.
1. Set everything up, ensuring the pole is sturdy and absolutely plumb.
2. Attach the dish to the motor and to the pole, the motor should be at 0.
3. Set the approximate angles, on your motor.
4. Attach the LNB, also set to 0, and your cable.
5. Run the cable to your receiver, enter you Latitude, and Longitude, into your receiver, negative Longitude readings = West.
6. Use your receiver to send the motor, and dish, to 0.8W.
7. Attach the satellite meter , to the LNB, and connected to your receiver.
8. Loosen the clamps, holding your motor to the pole, just sufficient so that you can swing it round.
9. Find 0.8W, once you have 0, on your motor, will be pointing at your True South.
To aid finding 0.8W, go to dishpointer.com.
Enter your Postcode, and press Go.
Select Thor 0.8W, from the drop down satellite box.
Slowly zoom in, on the map, moving the green icon, to your house, then to where you plan to have the dish sited.
Follow the Green line and point your dish in that direction.
The satellite meter should help you find a satellite, which you can then scan in, on your receiver, and the channels should help you identify which satellite you are on.
If on 0.8W, then fine, if you're on a satellite further East swing your dish West, to the right, if standing behind the dish, if on a satellite further West, swing the dish left, again if standing behind the dish.
It really is a lot simpler than you think.
Just wait until you get your equipment and give yourself plenty of time. Take breaks in between, as it is time consuming, and does test your patience.
