All the info is
here, Carole;
As you will see, the 4 active Birds are Astra 1N, 2F and 2A, plus Eurobird 28A.
I imagine he gets everything from 2A (North & South Beams) and from Eurobird
But 1N and 2F have Narrow Beams (Which he won't get) and Wide Beams: 1N Pan-European Beam carries quite a lot of stuff which presumably he can get eg Channels on Transponders between 12148 - 12324 MHz.
2F carries very few Channels - for reasons we are not sure about.
When 2E comes into service, we expect 1N to be moved to 19.2E so assume 2E will largely take over the current duties of 1N.
And that is the state of anyone's current knowledge. I might have missed out a couple of fine details and feel sure someone will point any omissions out in due course!
So pass the link above to him and he will be able to check exactly which Birds and Beams he's getting now. The future cannot be foretold, though.
