# Fitting aerial socket

What I don't understand is why you can't split the cable, I mean it only a broadcast signal.

Sorry!

On the dish is an LNB (either single for traditional sky or quad for sky+)

The quad allowing for sky+ multiroom where you can have sky+ in more than one room.

I suppose you could - but it would mean watching the same channel

Don't understand, why? I'm not saying you're wrong, I just don't understand.

I'm not an expert but I believe it works very differently to normal TV.
For example, if you take a feed from the back of the skybox to another tv then it would show the same sky channel you're watching on the main tv.

It does, however, pipe through terrestrial (sp) tv as well which can be different.

God I wish I could explain things properly!

But surely if you split the signal after the f-connector on the face plate, then this would be exactly the same as having two seperate feeds from 2 different LNB outputs I don't see what the difference is (apart from potential signal loss). I wouldn't worry too much about, I'm probably wrong

yeah - that wouldn't work. I can't explain why though!!!

Fair enough

If you have 2 sockets, where do the two lengths of coax go to?

There are two holes in the back of the sky+ digibox (f connectors I guess)

I meant in the other direction, i.e. the ones behind the outlet plate running to the dish.

On the dish is an LNB which has four inputs - the two cables run into two of those inputs leaving two spare for another installation.

Inputs ? Outputs !

You're pushing it now! I'm right at the extent of my sky knowledge already! I thought I was being good using 'inputs' instead of just 'holes'!!!!

The whole point of sky+ is the ability to watch one channel whilst recording another

The box has two tuners and each one needs its own lnb

Both of those tuners communicate with a LNB by sending a tone/voltage
as it requires those commands to switch between Horizontal and Vertical polarities and High/Low bands.

A single cable carrying two sets of commands to a single LNB would cause problems

Does this help ?
