I assumed that this meant 28.2 degrees east of north.

Not for geosynchronous satellite positions it doesn't. The numbers
refer to lines of longitude (through the poles) and they're relative to
Greenwich.

28.2°E is on a meridian somewhere towards the far end of the Med. I'm
guessing an Arabic station? Obviously the satellites are all near the
Equator in terms of lattitude.

Assuming that you're in the UK your dish needs to point somewhat
"leftwards" of a locally vertical meridian plane, but it's still mainly
southwards. Stick it on a southern-facing wall, not eastern-facing.
