4 TV's One aerial

chipbeck

Just set up BT Vision at the mother in laws.

I've split the av out from the BT Vision box in order to replicate the set up she had before with sky. Current situation is as follows:-

Main Television - fine
Tv Two - fine
Tv Three - Only picks up certain channels - No ITV ones
Tv Four - Only picks up certain channels and the picture appears to run (i.e leaves colours behind when picture changes).

Does anyone think a signal booster could be the answer to my problems?

Splitting the signal into 2 halves the signal
Splitting the signal into 4 halves it again
The fact some tvs work and others dont makes me think youve just used longer lengths of wires when you SHOULD have used a proper splitter with an amplifier built in (So all feeds are equal)

So yes, you need a splitter/booster

I think the main problem is that when they had the sky box previously it had two rf outs, the BT box hasn't so I'm having to fiddle.

In effect it's aerial into main BT box, split at BT Box one for main tele one goes back out of the house to other sets.

I think id try a 2 way splitter from the box to the 1 main tv and the other feeds the way you have it set now. But ideally you want a 4 way splitter and feed each independently

I agree with you, but as the 'current' set up is to main tv then out through coax to rest of house I want to save her any wiring and just connect to existing coax.

Ah, you mean it goes 'through' the first tv? Then boost that one, or possible the one after (Misunderstood what you ment)

chipbeck

Yes it all revolves round the fact that the sky box had 2 rf outs.
In effect what I need to do is replicate this without having a second rf out at my disposal.

Wouldnt it be better to connect the first tv via a scart cable?

First TV is connected by Scart. I've set it up as in the digram that came with the BT Vision box. Problem would appear to be that BT VIsion is set up to be used on one TV.
Aerial goes into BT box, scart from BT Box to DVD, Scart from DVD to TV 1.
