Here we would focus on either 19.2E or 13E, 19.2E would probably be preferable because it puts the other two LNBs not too far off focus, but we have a very strong 28E.

In your location, 28E will be weaker, so the first thing to do, is to see if your dish will get all the transponders on 28E that you require.

You can make your current dish position with a marker so that you can go back to your current position if you need to.


I suspect that a working system would be one that has 28E LNB near the focus, with the other two LNBs to left(from behind dish). If you have problems getting enough signal on the offset LNBs, you may need to focus more westward, and have 28E as a small offset, but that would depend wheter there is sufficient signal to do that.
