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:
What is Saorview? | SAORVIEW
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?

M E M: Put your post code in the Digital UK checker and tick the "Detailed view" box:

This should be used as a guide. Local obstructions won't be taken into account.
See:
Digital UK - Postcode checker
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:

Reception of the Freeview NI Mux from Black Mountain will give you RT One, RT Two and TG4 only.

Just as an FYI for anyone, I live south of the border in Ardee. I have an LG Smart TV Freeview HD.
I am receiving Saorview and MUX BBCA, MUX A and MUX B perfectly without any problems since 10th October.
Based on this I'm pretty certain that come the 24th I'll have the full Saorview and Freeview HD service.

Eddie Bosano-Andrews:
The coverage is now outstanding in the Republic from Divis and Kilkeel, all the wayto Dublin and indeed Wicklow! See boards.ie. Its also excellent on the IOM and in SW Scotland, Argyll and parts of NW North Wales.
If you have a Freeview HD TV you are in business on the 24th as the Divis HDTV frequency is also 100kW.
