I have been trying to check the alignment of my 1.2m prime focus dish with polar mount and actuator.
It seems to me there are 3 things that can be `tweaked`, and I would be interested to know in which order to do them.
1. LNB position
2. Dish elevation - am I right in saying this is altered by moving a large, almost vertical, pole up and down. An arm from this pole is attached to the back of the dish and there is a nut on either side of the connection, so presumably I loosen the nuts and move the pole up and down?
3. Dish offset angle - is this the smaller sliding nut which is marked on a scale of 1-10, and mine is set to about 6? (I live in East Scotland).
My problem is if I set the lnb to its best position, and then change the offset angle, do I then go back to the lnb which may not now be in the best position. And if I change the elevation angle, does that mean the offset angle should be tweaked again?
Grateful for any help - if anyone can recommend a book on Motorised installation I`d also be very interested
