Chorus cable setup?

After moving house I've forgotten how all the cables are set up for chorus. Their customer support always seems to be busy.
Anyone able to check what goes where?

There's a small black box with a TV and an ANT connection. A set top box with a RF-IN and RF-OUT, and a scart cable.

Run a cable from the 'TV' connection into the aerial socket (RF in?) on your TV.

Just had look round the back of our setup...

The little black box powers your Chorus aerial, so plug the cable from the aerial into the 'ANT' port on it and then run a cable from the 'TV' port to the RF-in on your decoder box. Then run your SCART cable to your TV. (We've never used the RF out, but I assume it would run to your RF-in on your TV, which would then need to be tuned to a certain frequency to get the signal.)

Hope that makes sense!
