I searched around for a Sky compatible distribution amplifier so that I could rig up a magic eye device for my bedroom TV. I finally bit the bullet and decided on this one.
There is 1 input and 4 outputs on the amp, using F-type connectors - which I preferred as the ends don't slip off as easily. The best thing about this amp is that it does not need a power supply and powers itself from the RF2 output on the Sky box - you need to turn on the power source (Settings - 4, 0, 1, Select to access the menu - RF settings). You need to make sure you take your Sky box output from RF2 only.
After that, it's pretty simple - plug in the cables, hook up the magic eye on the required TV and hey presto, Sky control from my bedroom TV.
