I only need 2, maybe 3 live - but I'll need to cut the cable for the ground floor to go into the connector for whichever alcove I want live.How many RF sockets are you running in the house.
If more than 8 I would be inclined to add another aerial outside or inside and split the distribution between 2 - 6/8 way amps.
This is just the way I would go.
Upstairs I'll need it permanently split 2 ways I reckon.
