I have added information to the UK Free TV database to cover the so-called mini-multiplex that will carry three Irish channels, TG4, RTE1 and RTE2 in a very special multiplex from three transmitters in Northern Ireland.
However, you will not be able to view these services using a standard-definition Freeview receiver - a Freeview HDbox or set will be required. It is not known at this time if the NIMM will carry RTE2 in HD, as per the Saorview service. TG4 and RTE1 are broadcast in standard definition at the moment.

I very much doubt Saorview from Clermont Cairn will reach Larne Paul, even with the increase in power on October 24th.
If you're getting a patchy signal from Divis at present then things should be much better (if not perfect) after DSO. I'm not sure about the NIMM from Black Mountain. If what Mike is saying is true i.e re. the technical paramaters then you may be OK. I do know that some of the higher parts of Larne enjoy Freeview from Divis even now, so maybe a replacement aerial may help
Failing all that, the situation with Saorsat should become clearer over the next few months so that might be the better option, if you don't want to bother with the subscription service on Sky.
Scottish TV shouldn't be a problem with either the Stranraer or Portpatrick transmitters, although both are Freeview Lite.
My point Peter Henderson is while Welsh people were looking for ways to receive improved receptiono of Irish TV a mentality existed in our small island which sought to deny Irish people of stronger Irish tv signals.
Sometimes there are licensing issues with programmes broadcast on certain platforms. Could it be that RTÉ will not be able to broadcast certain content (e.g. particular films) north of the border due to licensing issues and that this will mean that if it supplied it in HD, it would have to be a different HD feed to that in Ireland so as to allow opt outs?
Dave Lindsay: Yes, as I think Mike said above, you get better coverage for the same signal output, DVB-T2 "co-operates" better and the RoI services are in MPEG4, which is part of Freeview HD in the UK. Ofcom specifically banned using MPEG4 on DVB-T.
Given that NI is the very last region to switch in the UK, there should be mainly FreeviewHD in the shops by then.
Yes, they could have done a MPEG2/DVB-T solution but the coverage would have been poor.
Ronan: is there any high powered transmitters on the isle of man...i.m a tv dxer and enjoy it..i.ve a samsung 46 inch tv mpeg 2 and mpeg 4 combined so can recieve freeview from ni and possibly wales from clandonna and have clear view to isle of man wonder is there any horizontal transmissions from there ..thanks for your help
briantist i.d like to recieve manx radio on fm and made numerous enquiries to various satellite dealers looking for a 8 element directional fm aerial as i.ve a clear view to isle of man from my location..do you know anywhere i could get an 8 element fm aerial..thanks for all your help

Manx radio via FM
Have you tried a google search?
I found many dealers online with a simple search.
I'm located in the NW corner of Essex and could get Capital FM from Crystal Palace on a 6 element antiferance yargi all through the 80's & 90's up till I upgraded two years back to an 8 element yargi pointing the 6 element sort of towards BBC oxford, Good luck
Don,t forget hight is important as is a low loss down lead with no joints in the run Re hight signal quadrouples each time hight doubles , but beware signal loss in feeder
I found one finally from uk..its an 8 element directional aerial and have 10 ft pole on chimney clear view out to sea..isle of man is roughly 50 miles away approx and can get manx radio on car radio up near dublin mountains.. i.m about 60 ft above sea level...by the way how far does digital tv signals travel as divis is roughly 90 miles away and will transmit 100 kw of radiating power..i can recieve it in poor analogue at moment using amp . will digital make much difference...thank you for help..
So a quick update from partially successful testing at the weekend.
I bought a Labgear 450W aerial last week (triple decker wideband yagi with 16.5dB gain) and hooked it up to a SaorView TV (powered off an AC inverter in the car) via a DVB-T signal strength meter on some high ground (on an adjustable 6ft pole) near whitehead lighthouse and aimed it vaguely south to see if I could pickup SaorView.
Setup with Vertical polarisation I positioned it halfway between the points where signal strength fell to 50dBuV so I had a solid reading of 60dBuV on the meter (two lights)... Then performed a channelscan and was a bit surprised to see the TV pickup a lot of UK Freeview channels - which I wasn't expecting on VERTICAL - it must have been working off a Freeview repeater in range (but I thought they were very limited range).
The TV couldn't find anything at channels 52 (RTE1) or 53 (SaorView) as I expected from Clermont Cairn, but it did find RTE1, TV3 and TG4 on analog elsewhere in the spectrum. I was too busy holding the aerial in the stiff breeze to see where it found them.
So... is it worth me trying a mast-head amplifier along with a filter that blocks channels 21-48 to give me a better chance of latching onto the Clermont Cairn feed so far North or am I way too optimistic ?

The UK Freeview channels are possibly from the Isle of Mann (or maybe Portpatrick or Stranraer) as there are no vertically polarised Freeview transmissions in the province at the moment (try checking the BBC region).
After the increase in power from Saorview from Clermont Cairn post DSO, It's quite possible you may get a signal from Saorview, despite the Whitehead transmitter being on the same frequency (channel 52). It's very low power and could probably be nulled out.
Ronan o dwyer: Analogue switch-off on the island of Ireland is not until 24 October. All four services are still broadcasting from Three Rock, RTÉ One on C29, RTÉ Two on C33, TV3 on C35 and TG4 on C55, all at 25 kW. Three Rock broadcasts the first Saorview multiplex on C54 at 63 kW, quite an increment when digital services are usually considered equivalent at one-fifth to one-tenth the power of analogue!
We don't yet know which channel will be used, unfortunately, so you may have to gamble on wideband.
If you're the same Iderown on Boards.ie, you should be good to stick with your Group C/D on Clermont Carn. Saorview from there will be 160kW digital after analogue switch-off, which is approximately equivalent to 800kW analogue using the scaling factors that the UK uses to set the digital power level. The current analogue output at Clermont Carn is 250kW. Saorview signals are currently restricted to the north, that restriction is lifted on 24 October. It will replace RTÉ One on C52, so if you have good reception of that already, you'll probably get good results from Saorview directly.
Thank you for that Mike Dimmick. Yes, I am the same Iderown. Reception from Clermont Carn (analogue) is marginal to reasonable at Bangor (North Down).
I will most likely hedge the bets, leave the group C/D (V) aerial on the chimney, and keep the diary empty for a few days at the end of October!
It will be an interesting time.
Minister of State for Northern Ireland Hugo Swire said:"This announcement is the culmination of a great deal of work involving the UK and Irish governments, the broadcasters themselves and the regulatory bodies.
"I'm pleased to welcome this important practical step, which will increase the coverage of RTE1 and 2 and importantly of TG4 following digital switchover later this year."
Communications Minister Ed Vaizey said: "I'm delighted that the digital future for TG4, RTE One and RTE Two in Northern Ireland is now strengthened and secure.
"Today's announcement is good news for viewers and continues our delivery on commitments set out in the Good Friday agreement."
Irish Minister for Communications Pat Rabbitte added: "This announcement means that from Analogue Switch-off on 24 October, over 90% of viewers in Northern Ireland will be able to receive TG4 and the two primary RTE channels in digital.
"It is a hugely positive result in terms of practical cooperation resulting from the Good Friday Agreement."
No information on the Guard Interval, but since the obvious pairing of Carnmoney Hill and Black Mountain are on different frequencies, I expect it'll be 1/128. Similarly it will probably use Pilot Pattern 7 to match the HD mode. The recommended configuration in the DVB-T2 Implementation Guide gives 9.954 Mbit/s (the frame lengths can also be altered in T2). Using this mode requires 2.6 - 2.8 dB less signal, compared to the noise level, than the 16QAM 1/2 mode previously suggested, and 14.7 - 15.8 dB less than the HD mode. That's equivalent to broadcasting at 29.5x - 38x the power of the HD mux.
The change in mode could be down to the power level permitted at Brougher Mountain, which is half that previously indicated (i.e. 3 dB less).
Conor: There is no way RTE would consider going free-to-air on the Sky /Freesat group of satellites as such a move would cause problems with TV rights with the signal being available over so many countries in Europe. That is why Saorsat is using a satellite which does not reach beyond Wales. There are many viewers in England who would welcome the chance to receive RTE, but sadly real choice has actually gone down (without using equipment to receive from other orbital positions) since satellite transmission was first introduced on Astra 1A in the early days of Sky.
the people who have freeview are going to have to move to freesat because this 4g is a lot worse than what they are saying Bt vision are starting to go down the freesat route to get over this they have told me that they are in talks with freesat box manufactures so rte may go on to freesat any way to satisfy the good friday agreement
I've been told, in no uncertain terms, that RTE will never, ever, be on Freesat, ever.
It's all down to rights issues. Apparently the Irish government believe that if RTE were free to air ad 28.2 degrees east, millions of people in the UK (and all across Europe) would be tuning in and watching their programmes (some US series air before the UK, or are exclusive to RTE for example).
Hence Saorsat, which has a very narrow spot beam and will not be receivable in the UK (apart from west Wales, South West England, and maybe South West Scotland), and the need for the NI mux.
Personally, I think Saorsat may be a dead duck, in my opinion (lack of equipment for example, will installers even bother ?).
Still, time will tell.
It'll be interesting to see Clermont Cairn's coverage after October 24th.
i have bought a triax t2-td pvr is there any way of connecting to internet to receive extra channels triax says it cannot be done i connected it up the other night i got the conection it lasted for about 15 teen minutes then losted it it did not work since could any body help me
