Sky+ cabling question
Discussion
Afternoon all,
We're on the final snagging stages of our extension. All along, I've said I wanted an aerial socket and a twin satellite socket. I've just come back to find they've put in an aerial socket and a single satellite socket.
Before I get them to redo the thing - which potentially would require quite a lot of work - can someone confirm if I need them to?
My understanding is that Freeview boxes have internal twin tuners which can share the feed from a single aerial input (hence the single aerial socket) but that Sky+ needs a cable from the dish to the box for each tuner, hence the request for the twin socket. Is this correct?
Certainly when we had Sky+ this was how it was set up, and I wouldn't want to get Sky HD at some point in the future and find out I can only watch a single channel at any given time.

There are a couple of technical tricks you can do to get either 2 x Satellite down a single cable or a Freeview and Satellite down a single cable.
Before you force them to re-do the work, you could just get a discount from them. They think they have go away with some thing and you go and buy 10 - 20 quids worth off parts to fix it.
That is provided both aerial cable and sat cable come together else where before they come down to the new extension.

Are the fronts on yet?
Maybe the fitter has designed it that way, triplexer in the loft that feeds sat and normal aerial feed down one cable and the other cable carries the 2nd sat feed. A triplexing plate on the other end splits the two sat/aerial feeds again.
However if it was me doing it I would have run in 3 cables to get a return feed from the sky box to feed the other tv's. Actually I would have put in 4 cables as I have gone off the triplexing idea just lately.
Or you can buy a stacker/destacker unit for about £50 that will feed 2 dish feeds down a single cable, or a more expensive version that will do 4+aerial.

I don't know the details, but all the cabling will come direct from the Sky dish and/or the TV aerial. There certainly isn't anything in the loft, as we've had a loft conversion, so there's nowhere they could've hidden anything, and there's nothing visible.
The front plates are on, and there's only 2 phyiscal connections - one for Sky and one aerial socket - which leads me to assume they've cocked up rather than done something clever.

You cant get 2 feeds from one, what you can do is send 2 signals down one cable then split them, so you need a box at the dish end (called a diplexer or triplexer dependent on how many signals you are cramming down 1 cable) then at the living room end you fit a diplexing or triplexing wall plate that will split the signals so they are useable again.

Cheers for this, will look into these now. Will just have to work out how to get near the dish, it's a small block of flats with about 20 properties! Have the cables been laid in trunking,if so you might be able pull another cable though.When i renovated my house i ran twin sky and Aeriel and phone cable to every room in 1 inch tubing plus some string in case i need to pull more cables,massive over kill as out of 8 rooms only the living room has sky.You can never have enough cables.

Just for reference, you can only diplex / triplex signals together if they are all different.
ie. TV, FM and Satellite would work as they are all at different frequencies.
Sat1 and Sat2 would not work as they are the same frequency group.

Would splitting the one signal and then amping it not work? Interference allowing.ie. TV, FM and Satellite would work as they are all at different frequencies.
Sat1 and Sat2 would not work as they are the same frequency group.

There IS a box you can buy that will multiplex two LNB feeds down one cable, but it's expensive. I think it does it by converting one of the feeds to a higher frequency. You need a corresponding box at the other end to shift it back down again. When I remember what it's called I'll post the link.ie.
