I'm currently using a set of these in the UK
http://www.systemsat.co.uk/satellite-lnbs/inverto-black-single-ultra-0-2db-high-gain-low-noise-lnb.html?gclid=CM2I3-CRvrkCFcbLtAodxRAAaw

and the signal is amazing (up to 16dB on the Dreambox 800) where the normal signal rate is around 10 to 11dB.

Are LNB specifications any different for NZ (to be used on the Optus D1/D2/C1 satellites) or are these bad boys good to go?

LNB's for Europe are usually set to receive 11GHz signals and have 9.75 or 10GHz LO Frequencies as their primary setting. This LNB can do 10.6GHz too, so will work with our frequencies on Optus OK.

Yes, noise figure matters, but so does stability. And these are only good for +/- 1MHz which is a bit loose. I think that having an LNB that matches your dish's curve (f/D ratio) and size matters more than most specs.

Unfortunately with LNB's, it's more often a case of trial and error to find a good one that matches your dish. If you're after that extra few dB, then by all means, try a few LNB's to find a better one.




don't mess with me.... i'm the hd insider....
