I'm looking to upgrade the LNB on my SKY dish from a twin feed to a Quad feed LNB so that I can run cables to my Panasonic VT65 plasma which has twin Freesat connections on it. My local TV mast has only 15 TV channels on it so there are occasions when the SKY box is recording 2 channels (eg. SKY 1 and Alibi HD) and I wish to watch another such as DAVE at the same time. What would be the best option in getting this done; going to SKY - as it's their dish and LNB that would be upgraded. Will sky do this as the additional cable would only be going to a Freesat connection. Independent installer - how much would they charge compared to SKY. DIY - How difficult is it to swap and realign the LNB I've got a SKY+HD box currently and have no intension of having a multi-room skybox so the extra cables will be for Freesat only. Thanks for any help.
