Splitting the LNB feed

Splitting the LNB feed is not a good idea because it will reduce the signal by more than 50% and because only one receiver (or tuner, in the case of a twin-tuner receiver) is allowed to control the LNB at a time. (It can be done but there are compromises - if you really need to split the feed, click here.

There are better alternatives - read on...

The preferred solution is to replace your LNB on the dish with one that has additional outputs. If you have a SKY+ or Sky-HD system, you will already have a quad-output LNB as shown in the photograph. You can run up to four feeds from this. If you need more than four, we can supply an OCTO (8 output LNB - see LNB pages) and, if you need even more, we can supply a "multiswitch" unit.

Another possibility - if you want to install your receiver at one end of a room but want the option to move it to the other end, later, is to bring the LNB cable to a twin socket plate (see below). The spare socket can be cabled to a single socket plate at the other end of the room. When you want to move your equipment you simply screw a U-shape "patch lead" between the two connectors and your LNB feed will be extended to the second plate. This method is reasonably neat but has the disadvantage that it has three connections which can degrade the signal. The U-link cable should not be less than 200mm long, otherwise the cable might kink. We can supply a 200mm length with "F" connectors fitted. Order ".2" for the "Quantity" on page 8.

The third method is to use a manually-operated LNB switch. This has the disadvantage that it can lose a significant amount of signal and may therefore give problems with reception if your signal is already borderline.

The fourth method is to use an SPS1 switch as decribed here:
