hooking up to an existing dish
I purchased a home that has a Directv dish installed. There's a very intricate entertainment system throughout the home. I have determined which cable is running from the antenna outside into the entertainment box.
When I hook up one of my existing receivers (anH21), the screen shows an error message 775. There's a signal I have determined. In my investigation online, there appears to be different LNBs on different dishes? There's a need for a SWiM unit or a BBC device?
Can anyone enlighten me please?

Yes, the H25 will require a Single Wire Multiswitch dish and power supply. What sort of DirecTV dish is on the house? It will need to be a newer SlimLine HD dish.

A SWM LNB will need a power inserter to power it, the H21 will not be able to power it.
