A while back I tried going to the Norsat web page to look up the specs, and I couldn't find my LNB, even though I bought it not that long ago (within the last 2 years anyway). I bought it from a respected dealer, but I'm guessing that he had a stock of older LNBs. He gave me several to choose from, and I chose one of the cheaper ones, which apparently was an older one.

In looking for specs, I did find a PDF file for the 4000 series, which explained the part numbers. Apparently the "06" in mine refers to the noise figure, the "A" refers to the frequency range, the first "7" refers to the series number, and the second "7" refers to the stability. However the stability chart on the pdf file didn't go up to "7". It had "1"=150, "2"=250, and "5"=500, so I'd have to assume that "7" was 750.
From this chart, the 2707A would also be 750 KHz, but would have 0.7 noise figure, and would be a series 2000 lnb.

yeah i seen that chart Bill just never saw the 7706a but makes sense the way it's coded.
