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.

MEM: They gave BBC2 analogue a lovely send-off here in NI. Later with Jools suddenly stopped and it switched to a still caption about the DSO. Then it cut to a clip of the old 80's stripy BBC2 logo which unrolled as the announcer explained that analogue BBC2 was coming to an end after 48 and a half years then BANG out it went!

when can i receive the rte channels on freesat and freeview i live in bt72bt

mckeownsean: RT channels will not be available via Freesat.
The transmitter that is used in your area would appear to be Divis. It won't broadcast RT but instead it will be broadcast from the adjacent Black Mountain transmitter. There will be many places where a single aerial will be able to receive from both where they are roughly in line.
From your location Divis is at 288 degrees and Black Mountain is at 265 degrees.
In order to receive RT/TG4 channels from Black Mountain you will need a Freeview HD receiver. The broadcasts will be in standard definition but they use DVB-T2 transmission mode which is that used for Freeview HD services, whereas standard definition ones use DVB-T.
The main thing I can see, and it will depend on your exact location, is that the white building to the left of the Radisson could perhaps be in the way for Black Mountain, but as I say, this depends on whereabouts you live and whether it is in that direction.
Try it and see on 24th, if you have a HD receiver.
If it turns out that you can't get RT from Black Mountain using your existing aerial, then it may be possible to replace the aerial (to get reception from Black Mountain and Divis), or failing that, Carnmoney Hill is also broadcasting RT and Digital UK suggests that you might be able to receive that.
As ever, take what the predictor says with a pinch of salt. Local obstructions are not taken into account.
Reception of RT from Carnmoney Hill (if possible) would require a separate aerial and this (along with the Divis one) could be combined into one feed. Again, you will need a Freeview HD receiver to watch it.

mckeownsean: Or it "may" be possible to receive from Clermont Carn in Co. Louth. I have spotted an aerial which appears to be pointing at it near to you on 36 Upper Stanfield Street, so this may add weight to that as a possibility.
That said, it is important to emphasise that local buildings could scupper your chances and therefore what can and cannot be received from varies from property to property.
The only warning to give is that reception of Saorview signals from Clermont Carn will probably require a Freeview HD receiver. This is because of the different digital systems used in the UK and in the Republic of Ireland.
If you go down the route of receiving from Clermont Carn, then these questions might be of help:

mckeownsean: And finally, Clermont Carn will not go onto full transmission power until 24th, so don't do anything before then.
The NI Mux from Black Mountain and Carnmoney Hill will carry RT One, RT Two and TG4 only. See:
What is Saorview? | SAORVIEW
Clermont Carn will carry more channels:

As I say, your possibilities depend on what can be received at your location.

dermot walsh : You will need a Freeview HD receiver to pick up RT/TG4 as they broadcast using the DVB-T2 format even though they will be standard definition pictures.

I'm happy to say that I'm receiving all the BBC digital channels as well as radio channels with a good strong signal in the Newry BT35 area. I have to say in comparison to the analogue picture the digital picture is a lot better and more vibrant.
Before I buy a HD set top box for RTE is there any way I can find out if I can receive a decent enough signal to my home?

This should be used as a guide. Local obstructions won't be taken into account.

You may be able to receive Saorview from Clermont Carn for which you will probably need a Freeview HD receiver also.
Clermont Carn will give you Saorview channels:
