Co-Ax Cable Splitting + Magic Eye

Evening All,

I currently have Sky TV installed in the house, with the cable from the dish entering through a hole in the living room wall and connecting to the back of the Sky STB.

From the Sky STB I have a co-ax feed which goes to a wall plate, from that plate some co-ax cable goes up inside the wall, through the ceiling space, to a wall plate in the bedroom, and from there to a TV in the bedroom. This allows us to watch whatever channel is set on the Sky STB on the TV in the bedroom. The signal's great, everything works fine.

On top of this I have installed a 'magic eye' type thingy that allows me to use a sky remote upstairs to change the channel on the Sky STB downstairs, thus changing the channel that is being viewed on the TV in the bedroom.

I would now like to extend this functionality to another room.

So, I've split the co-ax cable just before it goes to the wall plate in the bedroom and installed one of these (complete with the required f-connectors to join the two cut ends of co-ax to the splitter): LINKAGE

The signal's great, and everything seems ok until (you've guessed it) I try to change channels..... Nothing happens..... I'm guessing that the signal from the magic eye is being passed back through the co-ax to the Sky STB (possibly via the braided copper shielding) and that this splitter doesn't pass that signal along.

So.....the crux of my post:

1. Am I right in my assumption? Has installing this splitter severed the connection that the magic eye uses to send the signal back to the STB, or have I accidentally done something else wrong?

2. If I am right, what's the fix? Is there a splitter available (preferably non-powered as I don't want to have to run power to this location as well) that will do the job?

3. If there isn't a splitter available, what other option do I have for a) fixing what I've 'broken', and b) doing what I want to do?

Thanks

Re: Co-Ax Cable Splitting + Magic Eye

hi m8 you are correct that splitter will not let the commands through only the power. what you need is 1 of these.

Re: Co-Ax Cable Splitting + Magic Eye

Thanks Iain, would I be right in thinking that the model you've linked to doesn't need a separate power supply and that it can draw the power it needs directly from the RF2 socket on the STB? That seems to be what the description is suggesting, just wanted to make sure.

Re: Co-Ax Cable Splitting + Magic Eye

Cool, ok, so.....

Can I assume then that if I put one of these in I should be able to have a magic eye on both televisions and they should both work, or will one interfere with the other?

Also, is that 9v being passed down the braiding or down the core?

Re: Co-Ax Cable Splitting + Magic Eye

yeah both cables can have a magic eye connected to it will work 100% the 9V comes down both parts of the cable + on one part and - on the other.

please be aware that this model is a f-type version and if u use screw on f-types DONT cut off the braiding

Re: Co-Ax Cable Splitting + Magic Eye

That's great

The braiding gets trapped between the rubber insulator and the screw fitting as it gets fitted doesn't it?

Iain, you're a bloomin' marvel - I'll let you know how it all goes when the new box arrives.

Cheers

Bought the same day Iain suggested it.

Delivered today.

Installed within 2 minutes of opening the box (well.....I did have to take the floorboard up).

Perfect picture and the Magic Eye works perfectly.

Thanks Iain, two thumbs fresh
