There is no guide as such,
What do you need to know,?
Make sure your mount is south facing, with a clear line of sight to the SATs you want to receive.
important, VERY IMPORTANT, your mount MUST be dead plumb in all planes, if its not dead plumb you will never get your setup sorted properly.
I'm fitting my motorised system in the next couple of weeks, weather and work permitting, and will try and do a step by step guide then.
