Sky+HD with a single LNB feed from the dish.
In the menu, set the Digibox to single input mode and connect the LNB cable to LNB input 1.
Sky Plus with a single LNB feed from the dish
With just one LNB feed, you'll have to set the box to record a programme starting slightly in advance of the one you want to record. It will result in a "failed" recording, since it will try to use LNB input 2, but it will also force the box to use LNB input 1 for the programme you want and it should record OK.

*Note: we are no longer recommending this product for use with Sky+ Digiboxes because people really don't understand the following information. Please do NOT order it unless you really understand how the twin-tuner Sky+ Digibox works. We will no longer be sympathetic to those who complain "it doesn't work" or "there's no signal on output 2". Think about it logically: if one receiver input is putting out 13 volts (for vertical polarisation) and one is putting out 18v (for horizontal polarisation) then the 18 volts is going to win and the input expecting to see a vertically polarised channel will see nothing. This is normal. The system will work only when both inputs are looking at a channel with the same polarisation (vert or hor) and the same band (high or low).

"I am interested in this product to use with my Sky+ box as I only have one feed. What functionality will I lose as stated in the description of the product?"
The LNB selects horizontal polarisation when fed with 18 volts and vertical polarisation when fed with 13 volts.
The LNB selects high band when fed with 22 kHz tone and low band otherwise.
If you connect two tuners to it, they will be fighting for control. Normally "high band" and "horizontal" will win.
You need a chart with four lists (download file below*):-
1. Channels with vertical polarisation and low band
2. Channels with vertical polarisation and high band
3. Channels with horizontal polarisation and low band
4. Channels with horizontal polarisation and high band

With a splitter fitted, you will be able to watch and record any two channels from any ONE of the four lists. You will not be able to watch and record, simultaneously, channels from two of the lists. You can order a splitter HERE. You can order suitable Low cost extension cable cut lengths with F connectors HERE.
NOTE: All splitters cut the available signal in half AND waste a little in the process. Think of cutting an apple in half with a blunt axe. So each splitter output provides only about 40% of the original signal strength. If your cable run is short and your dish size is adequate, this might not pose a problem as the signal will still be above the minimum threshold for your receiver. However, if your "rain margin" is already low, a splitter could have a very bad effect on reception.
In addition, this type of splitter contains two diodes, which prevent the LNB voltage from one tuner getting into the other. A diode can drop up to a volt when current is being fed to the LNB, and this can cause odd effects where the LNB may not switch to high-band when it ought to. If you observe this symptom, you could try a different LNB.
Basically, using a splitter is "pot luck". It might work for you but it might not. There are too many variables to allow us to predict the outcome for certain.
It may also be possible to use an obsolete SPS1 LNB switch if you can find one. If you search the Digital spy forum you'll find lots of discussions about using SKY+ and SkyHD with just one feed. Here's a few:
