Hi

I have a client that wants to combine RF signals (from his sky box, Media Centre PC and Roof Top VHF antenna) into one cable. Is there a little thing that does this? What is it called? It is like a splitter but in reverse (can I just use a splitter?)

I know and have told him that RF cable are the worst for picture quality, but he need to get his lounge TV pictures through to a bedroom, the house is already RF wired and he rents.

Thanks

I assume that the Media PC has an aerial In/Out, and if the sky box has the same, you could try just daisy chaining them on to the VHF feed in the lounge before firing them to the bedroom, ( make sure that the PC and sky box are modulating on a separate channel )

I just use one like this but in reverse.

If it is a standard Pace Sky Digital box like I have then you may need an attenuator on the outlet because it swamps the other RF signals with noise.

To do a proper job you need a RF combiner. This allows you to plug multiple RF inputs and get a single RF output. Hills do a nice 8 way one but I have no idea of the current cost. A local electrical wholesaler such as Corys/Mastertrade would be able to source one from them.

The media centre will have an RF Modulator - ugly but that's what he wants.
I will look into the combiner, we have an account at JA Russell, they should be alble to get one.
