Sorry, it doesn't work like that!
Since Saorview is the equivalent of Freeview (and not Freesat) it's a terrestrial system. That means that it requires a conventional TV aerial (not a dish) to be pointed at a nearby land-based transmitter (not a satellite). The signals used by terrestrial TV services are on completely different frequencies to those used by satellite TV; the receiving equipment for one system is not compatible with the other.
Any satellite receiver attached to a dish pointing to '28 degrees east' (which is the collective location for a group of satellites) can receive all of these stations, free of charge:

That's because none of those broadcasters encrypt their signals. However you'll see that RTÉ isn't in the list; that's because the transmissions are encrypted and can only be decoded by a suitable box with a valid viewing card (requiring a subscription) inserted.
