essexdelboy:I've retired to live in south west France and get currently Free to Air sat TV channels on my quad LNB with a 60 cms dish. I now want to get a large screen LCD with a Fressat integrated receiver so that I can get HD TV channels. I'd prefer a 46 inch Sony, whenever they finally get around to producing one. What 'hardware' will I need to get with such an installation? Will I need a special quad LNB?Assuming your dish is aligned to Astra2/Eurobird1 satellite's that Sky/Freesat use, then all that is required is an extra feed running from your current quad LNB (assuming it has a spare port), to the Freesat intergrated tv's tuner.
If your LNB doesn't have a spare port,(i.e all the output's are being used) then you can upgrade from a Quad to an Octo LNB(8 port's as the name suggest's).
There isn't anything special about Freesat/Sky LNB's as such, they're standard 'universal' LNB's like any other.
Though the ones that are used with the mini-eliptical dishes,like we use in UK,have a special bayonet fitment that pushes into the end of the dish arm.The LNB's used with standard offset dishes have a 40mm collar/clamp arrangement.
Hope that help's!
