I 've just replaced my single LNB with a Quad for future installs around the house. However I was told the quad has nearly 50% less signal strength than the single LNB. Personally I cannot tell the difference on when accessing the menus or picture quality, but I am a bit concerned when the weather turns bad that it's going to be less tolerant!? Also would the signal strength get less and less the more I feed from it for a Sky + box and normal digibox around the house? The quad is a Raven design but I am wondering whether theres any better quads on the market giving out better signal? Also anyone know where I could buy one from?
