    That looked exactly like the one I had mine replaced with so I went back and found my post about the problems I was having with my LNB since I recall mentioning the brands. I guess being on the wrong side of 40 is starting to show because I remembered it all wrong even though it has only been a month. My new one was an Eagle Aspen, your picture and mention of the three bubbles on the 99/101/103 cover jogged my memory. The old one was a WNC. I remember that one having three flat sort of chalky white covers. So I guess my installer has had the same experience with WNC LNBs that you have.

    It's ironic since the reason I bought a new one to have it replaced is because I started having problems with channels on 103ca breaking up every once in a while, just like you reported. It worked fine 99% of the time, but every once in a while it have problems on 103, while 99 and 101 were never a problem.

    Yep, I have been to many service calls where I have to do IVR (Installation Verification Re-test) and It fails on the 103 (usually even TPNDs) changing the LNB (without moving the dish) passes IVR. SO no my habit is if I see this LNB, I would change it regardless

    Update....new LNB arrived overnight from Amazon (with free shipping even) and has just been installed. Problem gone! All 103ca odd and even transponders are all very high 80's to mid 90's, and the other sats are all in the 90's as well. No manufacturer name is on the LNB, but it is somewhat different than the old one in that it has a translucent cover as opposed to the old one that was solid white. It is SL3K4NR0-02 if that means anything....

    Thanks again for everyones help on this :)

    IIRC, that is an Eagle/Aspen. Those are the "good ones"

    Thanks for the info peds48...it could be my imagination, but it seems like the picture quality is somewhat better than it was before. It seems to be a bit better in color and contrast and overall quality.

    Thanks again!

    It must be your imagination, Directv broadcasts a digital signal with a lot of error correction capability. After any required error correction is applied, what you see is 100% identical to what Directv broadcasts to everyone. If it falls below the threshold where error correction can make it 100%, you'll see obvious visual artifacts. With only a small bit of further degradation you'll see no picture at all. Same story as with digital signals for OTA broadcasts and digital cable.

    Yep. There is no difference in picture quality. There might be a diference in signal quality however.
