[QUOTE="NWW, post: 839007, member: 372502"] An update to this: I have completely removed the LNB's, and added them again, along with a fourth one for 9E. So on the Triax multiLNB holder it goes likes this: (seen from behind the dish) 9E-13E-(center of the LNB arm)-19.2E-28.2E. 19.2 is as close as possible to the center of the holder. I had some issues at first with high frequency transponders on 19.2 not showing up, and only 70% SNR on Hotbird, and down to 40 on 28.2. I took it all down, applied some basic trigonometry using the distance from the center of the dish, and the spread between LNB's and spaced them out to the millimeter, added 9E, and set it all up again. The results are amazing! 9E: 80% to 90% SNR 13E: 90% to 100% SNR 19.2E: 95% to 100% SNR 28.2E: 80% to 100% SNR (on the BBC One/Two HD transponder!!!!) So all in all, it was an alignement issue as suggested! I'll take a picture shortly! [/QUOTE]
