The top photo shows what appears in each room. Please note I'm not intending to do A/V distribution in the house.

2 x CAT5e
2 x CT100 RF

Gives me two ethernet/serial/closing contact in each room. Also the ability to have a Sky+/Freesat PVR and terrestrial TV/Radio connection.

The dish and aerial outside, the bottom photo shows the quattro lnb.
