| 1416334 | 2016-02-21 03:24:00 | Hi Team Just been away for few days down among the Otage lakes (Wanaka, Hawea etc) and satellite TV reception was dreadful. I figured that the Otago issues were due to the wild weather but when we got back home to Auckland, I found that all terrestrial channels here at Chez Billy were pixillating at random intervals, and on all five sets. The channels are no longer transmitted separately, they come in a stack so to speak, so it is not unreasonable to expect that what affects one program is likely to affect all the others in the stack. Has anybody else been experiencing this random disruption across all terrestrial channels over the past few days? Cheers Billy 8-{) |

| 1416335 | 2016-02-21 03:36:00 | I'm not in Ak and I don't use satellite so I can't offer anything useful in the way of comparisons. However pixellating generally happens when the signal level is right on the margin and given that it's fairly clear and calm today that shouldn't be the case. Is it possible the dish has moved out of alignment during recent bad weather or a coax connector has gotten wet and degraded? Also with 5 sets I assume you use a splitter and possibly a signal amplifier, have you tried removing all that temporarily and connecting 1 set up directly ? I thought my UHF setup was pretty good and had an amp to split it to the bedroom at the far end of the house. When I started getting the sort of thing you describe I paid someone to come fix it (I am not great with heights and hate climbing on the roof). He replaced my coax, realigned the Aerial, took out the amplifier, and got me more signal strength than I'd ever had passively. A little humbling as I thought I was pretty good at that sort of thing, I've even made my Aerial a couple of times. Personally if going terrestrial is an option for you I'd consider that. It is a superior picture and doesn't suffer from the same weather issues. |

| 1416337 | 2016-02-21 06:35:00 | I don't have satellite, that was down in Otago, I have terrestrial only, with a VHF/UHF signal distribution amplifier. It is usually set for low levels of amplification, but even if set to full gain I still have random bursts of pixellation. Back to the drawing board! Cheers Billy 8-{) |

| 1416338 | 2016-02-21 06:42:00 | Just a thought - we've had some strong winds recently - check your antenna or the lead-in. | coldot (6847) | ||

| 1416340 | 2016-02-21 18:54:00 | Ah sorry, missed the terrestrial bit. Most of what I said still applies though. Check the Antenna Alignment and the Aerial connections. Added to that if you can look along the path of the Aerial and see if there are any new obstructions, trees, buildings, etc. Amps only work if you have a good enough signal to start with, if levels are too low going in they don't help at all. I'd still try a direct feed without it to start with just to see. My whole aerial used to move sideways in the wind until the stay was repaired. |

| 1416342 | 2016-02-23 05:16:00 | Yeah, Sunday, 7pm I briefly lost (no signal) channels 2, 3, 4. Signal strength is normally a solid 100%. There was another dropout a bit later in the evening also. It used to be we'd get our TV signal passed through a bunch of repeater stations, and it was vulnerable to weather events anywhere along the line. These days I suspect it gets streamed over copper or fibre to the broadcast points, but same story, the chain is only as strong as the weakest link. I think very hot weather also leads to some hardware issues, as this has typically been a summer issue for me. Given that the transmission gear is housed at the top of fairly deserted hilltops it is also vulnerable to vandals, so is housed in solid concrete bunkers which are likely not a pleasant environment for busy electronic gear. |

| 1416343 | 2016-02-23 23:32:00 | Well, it improved slowly over last evening, and so far today it has been back to normal. That saves me having to climb up and look at my antenna. Last night I tried briefly a set of Rabbit Ears (remember them?) In terms of field strength, with digital transmissions you either receive them well or you get a no-signal message with nothing in between, so although the signal was weak, when it did come on it showed the same issues as I was experiencing from my main signal source. From those results I have concluded that it was very likely an atmospheric/sun-spot type effect, probably excessive hot air blasting over the Pacific from the Trump Faction screaming in the streets. I installed my antennae and distribution system quite a few years back now and have overhauled the connections a few times since then. It is pretty comprehensive with outlets everywhere that I thought I might need one, including an underground run to the man shed. :D Cheers Billy 8-{) |
