We used Clipsal faceplates with ordinary coax sockets.
The aerial feed comes into the AV Room and routes through the Sat and TiVo, then goes back out into "Node Zero" (where you can see the picture of the 8-way amp on that link above). From there it's distributed round the house allowing you to watch Sat or TiVo in any room.
