I've read good reports on it, but I don't have one. There are people on here that do have it. I'm sure they will comment sooner or later. You might get a quicker answer from the C-band area? I'm sure it's an excellent lnb! Just can't confirm it for you?
I have one and it has worked flawlessly for the last year. I can't compare performance with anything current as it was a replacement for an old chapparral 50K LNB that was attached to the feedhorn that was given to me for free. All I can say is that the old LNB was not stable enough for my receiver to lock on to low symbol rate transponders (~4MS/s and below) whereas with the Norsat it has no issues.
I'm also of the opinion that the L.O. stability is just as important and maybe more important than Noise Figure - which has become a marketing tool these days and the numbers quoted are starting to look like pure fantasy.
