As I promise here is one of my resent test, done this past 3 of January,
The LNB tested is the Avenger 321, I choose this LNB because it has being classified HD Ready, I have tested old LNBs with new HD receivers and work OK, no missing TP's freq during a Blind Scan at all, but this new era of High Def some manufacturers are starting to mark their LNBs with this HD Ready logo, so I started with this one, first here is what I have, SkyBox S12 HD Mini PVR, OpenBox S10 HD Mini PVR, 9 dishes in the 4.5' feet and 2 5.5' feet all of them solid none are mesh nor fiberglass, in my area the Sats available to me are from 15west to 135west, everything 121 west and above are a bit difficult to aim but it can be done.
First test was with a dish wish is already fixed at 30west Hispasat, I removed the LNB FortecStar Quad Universal 0.3dB Noise I had with the Avenger 321, did the proper settings at the receiver's menu and exit the menu to see 1 of my favorites channels from this Sat channel Monte Carlo, first thing I notice was the quality signal meter, it improved from 73-76% that it fluctuates to 79-81%, then the image, image was very sharp color definition was improved also.
Second test was aiming a dish or Sat hunting as I like to call it using the Avenger on a 4.5' feet I have for test, using the Accutrac 22 Plus Sat Finder and the OpenBox S10 with Portable TV I started to Hunt Sat at 78west Known as Simon Bolivar, I enter this Sat's TP manually and started to hunt, Honestly in the Hunting I didn't see any difference at all found the Sat did the last adjustment to gain the best quality signal possible and did a Blind Scan, everyone that has owned an OpenBox knows this receiver's has a good tuner and good Blind Scan, but it is no secret they tend to skip 1 or 2 TPs during the Scan, but on this test is where I got surprised the OpenBox did the Blind Scan and didn't skip a single TP, some members don't think the same but I have chatted with a few old timers from this Hobby and they all said, "it doesn't matter how good a Blind Scan of a receiver can be it will be affected by the LNB's quality" It seems this LNB is well made, it was the first time my OpenBox did not skip a single TP.
I recommend this LNB, it really performs as I was expecting and the price is cheap, here are the LNB's specs
Input Freq: 11.70-12.75GHz
Output Freq: 950-2000
L.O. Freq: 10.75 GHz
