I currently have Sky plumbed into my house via 1 coax and one box. I have another sky box with it's own card and wish to connect it to my current coax. Here's where I need help. I've tried introducing a coax splitter/antenna splitter(no laughing at the back) and it seems to work fine with one box but when I try to wire the other box to it I get a "No Signal detected" message on both TV's/boxes. 1. Can it be done like this?(I've been told it can). 2. If it can be done like this, where am I going wrong? I've been told that it cannot be done with cable tv as the strength of the signal coming in from the street is determined by the box, ie:- the box is set to recieve a certain 'gain' and it will not work if the 'gain' is split. Is it the same with Sky? Help much appreciated.
