Iggy: You don't need a splitter to achieve that, just a twin satellite extension cable such as the one linked below which you can just disconnect if you later decide to move your TV back to its original position.

Then you only need to fix the twin cable to the external wall where it cannoit easily be reached by casual walkers. You can get fixings for twin cables easily, they are designed for twin coaxial cables so are wider than those for single coaxial cables. It is wise to maintain the twin feeds in case you wish to record one channel whilst watching another.

Note that you cannot 'split' satellite coaxial cables because of the way the control systems work for each individual element within the LNB (the small 'box' mounted in front of the dish face). The TV or Set Top Box (STB) controls the receiving elements within the LNB to get the services wanted for that device. If two devices wanted different services they would conflict and could possibly damage the LNB and maybe the receiver as well.

michael: The recorder has two tuners, but by the sound of it, your dish has only one LNB - the bit thats at the end of the dish. You need one for each tuner. Sky dishes might have one (for Sky), and two for Sky plus, etc.

Have a look at, which is all about sat. systems, and will show you how to see if your dish actually does have an extra LNB, but its simply not been connected up.

If you've only got one LNB, then you can only watch or record, so the best thing to do is to replace the single with a twin, or ever better, a quad (so if your TV has a Freesat tuner, you can use that, plus the recorder all at the same time). You can do it yourself, or pay someone to do it.

Further to that said by MikeB, and to clarify, your dish may have an LNB that has two (or more) units inside it.

If you can see where the present single cable enters the LNB on the arm in front of the dish, have a close look to see if there is another connector alongside the current cable. If there is, that can be connected via a second cable to your Freesat box to provide the second input required for recording whilst watching another programme.

If your LNB does not have a second outlet available, then your need to have just the LNB changed. You need at least a dual type but it is more common to fit a quad type, they are not expensive but need to be correctly fitted and aligned (it's not just a case of putting a new one in place of an old one as the new one has to be properly set at the correct angle away from vertical - it's called 'skew'). Any local aerial/dish installer can do that for you if you don't feel competent enough yourself.

The new cable used must be of the correct type for satellite signals (ordinary TV coaxial cable is not good enough for the much higher frequencies used for satellite reception). The 'F' connectors must be correctly fitted so that the required two LNB outputs can be used.

Then you should be able to record one programme whilst watching another. You can, of course, record one programme whilst not watching any other - even though you only have one downlead available.

I have a Sky Q box and had the cable fitted underneath my carpet.
The cable goes around the room.
Can the cable be cut and split so that I can move the TV to the other side of the room without having to pull up the cable that's underneath my carpet, plus leaving the cable live so it could be used again.
Hope this all makes sense

I don't have Sky Q, so I don't know exactly what the cable connections consist of, but I believe it's more than one coax.
I wouldn't recommend cutting it as you'd need the relevant connectors to go on the satellite end to plug back into your box, this might involve soldering.
Apart from which you'd need connectors on the loose end and/or some sort of coupler to rejoin them when you wanted to move it back.
I'd think it was far easier to move the cable from under the carpet.
