Correct, I am in Spain and aware that pointing at 28.2E would be the logical way to go as this would be the weaker signal and I would want this bang centre on the dish; trouble is I'm not even sure if I can "see" 28.2E from my garden (long story short, I'm aiming at a gap between my building and a neighbouring one and I can barely get 19.2E; 28.2E would be very fortunate).


Not sure If I understand correctly.

But... Why have you gone to the trouble to buy an offset bracket to get 28E and 19E on, if there's only a very slim chance that you have a view of 28e anyway?

Having 28E on the offset will not make your view of the sat any better than it would be at the focus.

80cm dish pointing at 19.2E with additional LNB set to pick up 28.2E, connected to a 2x1 DiSEqC switch. (Both LNBs are TWIN)

Well, I have a second house in Huelva, southwestern Spain, where I *do* have awesome visibility of any satellite I can think of. I bought the bracket in case I could get 28.2e here in Madrid, and if not, down to Huelva it goes, along with a new dish :)

28E on the left and 19E on the right.

Also, the 28E LNB should be slightly higher than the 19E one (which "reflects" to a lower effective elevation.

How close does the 19.2 lnb need to be? is there a set measurement or trial and error?

cheers

Too many variables involved to be able to say (focal length of dish/arm, lnb design etc). trial and error will be the best method

It would be approx 9 degrees away.
