The symbol shows the location of the Carnmoney Hill (Northern Ireland) transmitter which serves 21,000 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.
Are there any planned engineering works or unexpected transmitter faults on the Carnmoney Hill (Northern Ireland) mast?
Which Freeview channels does the Carnmoney Hill transmitter broadcast?If you have any kind of Freeview fault, follow this Freeview reset procedure first.
Digital television services are broadcast on a multiplexes (or Mux) where many stations occupy a single broadcast frequency, as shown below.
64QAM 8K 2/3 24.1Mb/s DVB-T MPEG2
DTG-6 256QAM 32KE 2/3 40.2Mb/s DVB-T2 MPEG4
DTG-11 QPSK 32KN 2/3 10.0Mb/s DVB-T2 MPEG4

The Carnmoney Hill (Northern Ireland) mast is not one of the extended Freeview HD (COM7 and COM8) transmitters, it does not provide these high definition (HD) channels: BBC Four HD, BBC News HD, CBeebies HD, Quest HD, Forces TV, FreeSports, More4 +1, Now 70s, PBS America +1, Quest Red +1, RT HD.
If you want to watch these HD channels, either use Freesat HD, or move your TV aerial must point to one of the 30 Full Freeview HD transmitters. For more information see the want to know which transmitters will carry extra Freeview HD? page.

Which companies have run the Channel 3 services in the Divis transmitter area
The issue has resolved now after several days. It was not working this morning and now later in the morning, all the channels on that mux are back (after communicating with various people last night and early this morning). You say that problematic connections, water ingress, etc., can seem to affect reception of just an individual mux. This is interesting and I will check for these things.

To get more technical, problematic connections etc. can result in what's called standing waves in the cable which are often frequency specific and so affecting one particular frequency more than others.
Major cable breaks will of course have an effect on all signals.
This is why it's a good idea to make a note of the signal strengths and quality of signals for all the multiplexes when your system has no faults, then when there's a problem it can help to identify to possible causes.
