[QUOTE="Llew, post: 403178, member: 175007"] Perhaps they are still using the noise figure meter (HP8907B) that they used for their earlier LNB testing? This had an instrument uncertainty of +/- 0.3dB, well out of accuracy for testing to low N/Fs. Maybe the quoted figure of later LNBs is much lower in practice? (only conjecture). Llew [/QUOTE]
