I don't want to use a satellite box I have a freeview box. I want to know if an existing dish for sky can be use with the freeview box.Can I use a cable splitter and run one end to the sky box the the other to a freeview box and get the freeview channels.
Elizabeth: You need an aerial for Freeview as your Skydish only receives satellite signals. If your TVs already have Freeview built in then you won't need a separate box. Have you checked that you don't have an aerial already on your roof or in the loft? You can split the feed from an aerial to feed as many TVs as you like although you may need an amplifier or powered splitter to overcome the drop in signal strength from splitting the aerial feed. You may be able to get away with using an indoor aerial if you're in a strong signal area but it would be best to consult a professional aerial installer if you need a new aerial fitted.
Roger Duncanson : Although that said by MikeB, i.e: opting to replace the existing LNB with a 4 output quad type is by far the best way to go for maximum flexibility, however, the satellite A-B switching device as seen in the link offers a simple way of using two satellite boxes on a single output LNB, said output of same connected into the middle socket on the switch, and with the two outer sockets connected into each of the two boxes.
By the way, this device can also used to enable a satellite receiver to be connected into two separate dishes, e.g: one dish set on 28.2 degrees (Sky) and the other on 19.2 degrees for European channels.
