Doesn't D11 also have Ka-hi tps? I will admit I have kept track.
As to the loss of the 1650-2150 range, it wouldn't change by peaking the 103 LNB, so that was pointless, and the dish alignment was what did it.
While I don't like picking on other members, this thread has shown the reason the last two installs I've seen out here had low numbers of the 99 & 103 setup screens and for both of them, peaking the Ka levels was needed, to regain about 10 points on the receivers.
IIRC the Ka LO in the LNB is 18.050 GHz, so Ka-lo downlink is 18.3 to 18.8 GHz, and Ka-hi is 19.5-20.2 GHz, but the main difference is the Ku being "only" in the 11-12 GHz range.
D11 is Ka-B-band 18.3-18.8ghz and after the LNB Ka-Lo 250-750mhz. The 103 is usually where everyone has problems passing IV because of the attenuation on longer cable runs, to many splitters, and if not peaked properly rain fade. As to the loss the dish alignment may have got him past the IV retest or it could have just slacked off on the rain??? no telling but if it was the dish alignment he didnt do it right the 1st time. Picking on someone?? lol This info comes from the people that run, design, control, whatever you want to call it at DTV so for one person to say they are all wrong is just silly to me. As for your 2 installs you saw with low signal that explains nothing there are alot of installers for DTv that as much as they are trained (although some are not) they still dont get it right it only explains they didnt do it right.
