I am trying to set up a dish for receiving satellite television.
I had assumed that I understood the meaning of, for example,
28.2 degrees East.
I assumed that this meant 28.2 degrees east of north.

Yes

Or possibly 28.2 degrees past east.

No

But then, what can 122.2 degrees East mean ?

122.2 degrees East of North!
or 32.2 degrees East of East if you must.
