The symbol shows the location of the Divis (Northern Ireland) transmitter which serves 440,000 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 Divis (Northern Ireland) mast?

Soarview have a plan, like Arqiva, to reallocate multiplexes to different channels as part of the 5G adjustments. They are working together to ensure that there is no interference between any channels.
At some stage, Soarview viewers will be required to retune as is happening with Freeview viewers.

MikeP: Well all I can say is it's going to be a disaster. I was out even today sorting out 4g issues and last week with customers years after it came in. Should never have been allowed in the first place.

4G uses parts of the spectrum that will not be used for digital television transmissions. The point us that these are being moved away from any 4G transmissions and sited below 700MHz where they should not be subject to interference from other transmissions. Surprisingly few people have had problems with the presence of 4G signals, especially those whose local transmitter uses the lower channels well below channel 60. Therefore there is no expectation of the disaster you fear.

Currently, no signal at this location from stations on Com 7 and Com 8 so I presume both multiplexes are off air.
Maybe some engineering work in preparation for next Wednesday's retune ?

Yes, that is correct Carl
Sometime in March they'll move again to 52 and 56

PeterH: thanks I assume there will be an issue then with 50/52 diplexers fitted for Freeview and RTE?
