The symbol shows the location of the Limavady (Northern Ireland) transmitter which serves 45,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.
This transmitter has no current reported problems

Hi, thanks for your replys, I have since retuned my tv again and I am now getting every channel but not the Film4 etc mux, is there technical reason why this might be happening, I am using a grid type aerial pointed towards limavady transmitter. Thanks. Brendan

I live in Donegal, and had perfect reception since last Wednesday, 24th, but since last night BBCB on ch 55 has disapppeared, the HD channels. The rest are perfect. What happened between Monday and Tuesday? (54.90831,-7.67339)

Ian Drury: Fanad broadcasts on C55, albeit vertically.

I know, but I was receiving BBCB Mux ch 55 from Limavady perfectly for six days, then nothing, how is that explained? (54.90831,-7.67339)

Ian Drury: Digital pictures are an all or nothing sort of thing. There is very little inbetween where they break up a bit. It is said that there is a "cliff edge" over which the picture can't be resolved.
If it is interference, for example from Fanad, then it could have been that, previously, whilst the picture was "perfect", the signal was being interfered with, but not to the degree to push you off the cliff.
What this means is that there is only a "slight" change to the level of degradation required to move from "only just" being good enough (which produces a "perfect" picture) to "only just" being not good enough (which produces no picture).
Such a change could have come about due to a change in the Fanad signal (if that is what is the cause) and this may be something that has moved and is causing a reflection in your direction. Or perhaps there was something that was acting to block or reduce the signal from Fanad that has now moved. Or maybe something has acted to reduce the signal from Limavady.
I mentioned that Fanad is co-channel simply as an observation. If you could receive analogue from Fanad (to some degree, even if not watchable, and particularly so on your Limavady aerial), then this might perhaps add weight to its digital signal being a possible cause of your woes.

Ian Drury: Should it prove to be interference from Fanad and you have a grid aerial, such as that shown in this picture, then perhaps a more directional aerial will be better:
Aerials, TV Aerial and Digital Aerial
Grid aerials have a wide acceptance angle and therefore less gain than more directional ones. This is because to get more gain, the aerial simply focuses on a narrower "beam".
Both Holywell Hill and Limavady are on similar bearings and a grid aerial with its wider acceptance angle would therefore be perfect for such an application. However, its wider acceptance angle leaves it open to picking up interference that a more directional antenna would be likely to "reject".
Obviously if the interference is eminating from the direction of the transmitter, then a more directional aerial will still pick it up.

I have a Televes Infinity 38 element somewher between a unix and a yagi. All the other muxes come in fine, BBCA is transmitted at the same power, and it's fine, my uhf meter gives the same signal strength for the two, and Fanad has not made any changes since the 24th.
I can see the Letterkenny transmitter out of my side window, 2 miles away, but that's on ch 53, and at 90deg to the aerial, I do get good reception from it, even though it's vertical polarisation. So That's not the culprit. Must be the 256 QAM as opposed to 64, so that's what I'll blame, still doesn't really explain it though.
Aerials and marginal uhf are a black art, I always thought, give me a tricky / weak satellite reception to get any day, way simpler to install.All you need is a big enough dish.
Good job I installed Freesat+HD a few years ago, faultless reception. (54.90831,-7.67339)

Ian Drury:
I am having trouble with channel 54 (738.0) on the Limavady transmitter.
I cannot tune in ITV 3 or the rest of the associated stations.
The signal strength usually "maximizes" at about 40 to 50% of total, however, it oscillates between Zero and the aforesaid maximums about 2/3 times every second.
Needless to say this makes it impossible to store any station broadcast on channel 54 (limavady)
can anyone offer an explanation?
is this interference caused by the local transmitter in Moville?
ironically, the channel is received interference free in Derry City.
I am receiving (in Malin Head Co.Donegal) all the other channels (including RTE etc) at a very high signal strength.
any help/information will be appreciated.
Jim

Jim Neary: The oscillation suggests that it could be too high a signal level. Try turning your amplifier down.
According to RTNL, only Kippure broadcasts on C54:

Hi,
Since the switch over I can receive all the HD channels but in 1080i. My neighbour about 150 yards away can receive in 1080P (when channels are being broadcast in 1080P). I live in Ringsend not far from Limavady (10 miles) but I think (not sure) that my signal comes from Divis as we have a mountain in between us and Limavady. I have an I-Can HD set-top box running a Sharp Aquos, I have tried this box at my neighbours it gets 1080P there running through a Sony Bravia . My aerial was a Yagi type high gain. I was getting a signal strength of 65% same as my neighbour. I then tried a Philex 27887D SLx 32 Element Digital Wideband Aerial made no difference except the signal strength was slightly lower at 62%.. Both my neighbour and I use a SLx 8 way distribution box to feed the signal around the house. My question is why can I not receive 1080P? Am I using the wrong aerial? or am I missing a trick somewhere else. Many thanks for any help you can give me.
