The Standard or Universal should be at the focus point of the dish for best signal.
Anybody who needs both, didn't plan well.
But, the Circular can be beside the main LNB.
The circular satellites put out a lot of power, and are much further apart in the sky.
Their alignment is far less critical.
But to get 119° on the circular LNB, you'll still need to motor the main LNB over to 125° or 113° or whatever direction puts the circular LNB pretty much on the desired bird.
As for wiring, see the Switches Simplified FAQ.
Bonus: the circular LNB has no skew to be concerned with.
easy setup
receiver----motor---diseqc switch---port 1 was KU
--------------------------------------------port 2 circular
--------------------------------------------port 3 Universal
doesnt matter how close they are. I put them next to each other
skew on mototrized is done via the motor so that is set at 0
DBS doesnt suffer because they are strong signals and on most DBS dishes the LNB"s are offset anyways. On a Dish500 the LNB's are 4.5 degrees off centre.
The only drawback is to set up DBS you need to compensate if you use USALS. The DBS LNB needs to have 5 degrees taken off of it. In the above to get say 110 DBS I actually aim the dish at 105.
The UNiversal I added 5-6 degrees. Its all trial and error honestly
This sound interesting. It will certainly be fun to play around with the setup. I can't wait.
