[QUOTE="dxsat, post: 374231, member: 193607"] I was told that in a 0.3db LNB the noise inherent in the components used was as low as can be manufactured in a practical way. The engineer said that you would have to cool the LNB down to something approaching absolute zero in liquid nitrogen to get a lower figure. 'Beyond physics' is what he said. Less than honest manufacturers claim these crazy figures knowing that 99% of users have no way of testing their validity. It's all down to marketing. You can safely disregard any claim for any LNB to have a 0.2db noise figure. There are now 'HD Ready' LNBs coming from Sharp. I thought this was an April Fool's joke at first, but I saw it on a Spanish distributor's website, and the Spanish have their own jokes day in a different month. [/QUOTE]
