DTT tests from Tonabrucky nr. Galway City

Galway

DTT tests from Tonabrucky nr. Galway City are now on air on Channel 23 which I can receive 16 miles north of the city.

Unfortunately, the Muxes from Tonabrucky are co channel with analogue from Castlebar and as quite a number of people use Cbar analogue from Castlegar onwards out the Tuam road , up into Tuam also this is causing their TG4 to become unwatchable. So much for frequency planning!

This Tx at Tonabrucky is co sited with the UPC main MMDS tx for city dwellers whose areas arent cabled and the for the whole of Co. Galway.

16 miles is damn good, it ain't meant to be very high power that one.

I have line of sight to the mast, can see red light on top at night. MMDS mast is very tall. Yes, its not on full power yet Id say, good on a crappy group A ten element contract.

Where exactly is the transmitter.

I'm getting faint signals from a home-made UHF grid type aerial with booster attached.

Horizontal or vertical?

It is only supposed to be a 1kw infill transmitter where Maghera is 150kw...but it may have been relocated from the Hynes Building in town which is where the Galway transmitter was supposed to go originally and not in Tonabrocky .....IIRC that is.

Channel 23 is Band A and everybody in Galway has a UHF Band B/C aerial if they have a UHF aerial. You need a Band A aerial and/or an amp that will amplify Band A ( not all will)

so called "Wideband" aerials are known to be crap in Band A so don't try that.

Could someone email rtenl.ie for a channel plan and coverage map for Tonabrocky so you know where it should work before you go out buying aerials for it. Also get the same data for the Loughrea transmitter that is due to go live over the summer. You may be sure they will not clash with Maghera

Found it using OSI, google and bing maps.

UHF aerials have a little bit of coloured plastic on them. They should be as follows according to this excellent page on aerials and tv .



If the piece of coloured plastic is green ( most common in Galway) then it is the wrong UHF aerial for channel 23 from Tonabrocky unless you live right beside it. You will need the red coloured one.

The Hirschmann aerial mentioned in this informative thread is apparently an excellent Group A aerial but first we need to find out what the Loughrea and Tonabrocky coverages and channels will be from RTENL.

Wonder why they have switched on Tonabrucky on Ch 23 again when it appeared to cause alot of interference to C'bar analogue in late March. See "Castlebar reduced power" thread of that time.

http://www.boards.ie/vbulletin/showthread.php?t=2055867998

In post #11 of that thread (Galway's) an RTE engineer seems to admit it's a problem! If it stays on ch 23 some sort of nulling in the C'bar direction will be needed.

Bob_Harris

Just tried out an indoor amplified aerial I got in Lidl a few weeks ago and it's receiving it fine, living near Ballybrit industrial estate.

Anyone receiving from Maghera in Galway will have a group C/D aerial for TV 3 and TG4. As said in my earlier post, a good number receive from Castlebar along the Tuam road where the Maghera signals esp RTEs 1 and 2 on Band 3 are severely attenuated by the hill at Ballybrit. These are using UHF group A aerials and will be/are being affected by the co channel DTT from Tonabrucky (as I am on Ch23 TG 4 some 18-20 miles north of Tonabursy A serious null to the north will be needed until ASO.

DO NOT use the Hirschmann FESA group aerial for IRISH DTT from a strong local Tx - it is total overkill and completely unnecessary give the high DTT powers that will be radiated from main Tx stations.

What is the point of this TX

Surely any areas served by it already has a perfectly usable signal from Maghera

Sponge Bob

The point was to serve 20000 people in the city centre with rabbits ears, it was planned at 250w ( 0.25kw) and to serve about 20000 people. Looks like it will cover up to 100,000

A Hirschmann FESA is unneccesary for DTT as Tonabrucky isnt on full power yet. The Maghera DTT on ch 48 is reaching further than the Band 3 and UHF analolgue services.

Sponge Bob wrote: »

Maghera DTT is receivable in Castlebar as is Truskmore DTT on CH 53. The new Truskmore mast is built and will provide better coverage from this TX. That is maybe why Cbar isnt happening yet.

The Loughrea DTT channels are adjacent to the Cairn Hill DTT and DTT Woodcock Hill, Limerick ones and co channel with Analogue from Woodcock Hill. Power will be low I guess to avoid intereference. I suspect the tx site will be at Derrybrien where i102-104 FM have a tx.

Well in fairness a lot of people rent and cannot put up a "proper" aerial.

This transmitter serves me very well, I can get it indoors with an amplified set top aerial.

Would you prefer if only a handful of transmitters existed and the entire population had to install high gain UHF aerials mounted on 10 meter poles with masthead amps for good measure?

What exactly is a "proper" aerial anyway?

Sponge Bob

But there are people who are shielded from Maghera north of Galway and the fact is that the list of transmitters I published is the list that is likely to be done. RTE ran out of €€s before they ordered any more gear....they have not tendered for any DTT TX gear since early 2009. Loughrea was supposed to be done same timescale as Casla and Clifden in 2011 ( both more powerful but serving a smaller population each) and was brought forward to be done around the same time as Galway.

I would not be surprised if Casla and Clifden are still running analogue in 2015

Perhaps it should be part of the minimum requirements for multi dwelling unite that such a thing be provided in this day and age ?

In the case of single dwelling units perhaps its something that more people should be asking about before signing a lease ?

Sufficent to recieve a signal of 60dBuV/m with EBU grade 4 or 5 reception at a height of 10 metres above the ground Is considered the standard in Ireland IIRC

Indoor reception is not feasible in Galway on analogue (very snowy pictures and two types of aerial needed - rabbits ears + UHF loop), so why is there a need to make indoor DTT reception available?

Indoor reception is designed for apartments and more especially those who don't have or want sky or cable but are willing to contribute for psb tv via the license fee.
DTT for the first time makes this more possible than ever.

How very odd. Other than the main transmitters and Greystones/Dungarvan only one other tender was ever sent out for TX gear , this one.

It looks like RTE sent the gear meant for Letterkenny Arranmore Loughrea and Skerries to Castlebar Knockmoyle Fermoy and Mitchelstown instead.

They have ordered no TX gear since that lot listed in the link a year ago.

Why should they buy more anyway?

Haven't they a surplus of tx equipment ready for dispersal to every population 5 person or more,currently dtt free nook and cranny in the country now due to the failure of the commercial mux sell off

How did apartment residents get their TV up to now ?

snowy indoor aerial or cable/sky.
Some would be lucky enough to have access to a communal roof aerial
They are however as entitled to proper psb reception like any other license payer.

They didn't, if NTL or UPC wasn't an option/cheap enough for them. I know that I wouldn't manange anything like decent RTÉ reception while I've lived in Dublin were it not for high-power DTT from Three Rock.

So why is 'indoor reception' now an issue with the advent of DTT?? So are non city residents blocked by high mountains or in remote areas of the country or apt dwellers in smaller towns also 'entitled to proper PSB reception like any other license [sic] payer'. I cant see RTÉNL erecting masts for valley communities or anyone else that cant get indoor reception. This is a totally spurious argument. There is NO NEED for a in fill Tx in Galway city given the high penetration of cable and where areas arent cabled MMDS. If the Irish terrestrials ever go free to air on satellite, this will mean wasteful duplication. The money could be better spent on providing a DTT service to those areas which have a real need. Again its a city versus rural bias.

I'd essentially agree with you.
But RTE wouldn't.

Sponge Bob

Cable is not terrestrial, were UPC prepared to give everyone free Maghera on cable in Galway then an infill would not be needed to deal with multipath signals and tall buildings etc. Until then they do need an infill.

But they are probably renting space to eircom on their MMDS mast so why would they ???

I don't agree with some of that. It's clear that many urban dwellers have poor RTÉ reception and can do nothing about it. I think forcing them into the hands of UPC on top of paying the license fee is not acceptable. Almost every rural house can install a rooftop aerial in comparison, so I think it reasonable that large urban areas are provided with stronger RTÉ reception.

I think there's a lot of merit for other relays in rural areas too, but if there's a few hundred people in Galway who can't watch RTE because they live in an apartment block, they should get a relay ahead of 20 people who live in a valley, surely? I know there are probably larger areas that need a relay, but I can't name any examples myself. By all means, if larger communities are struggling to get coverage, they should be accommodated.

And besides RTÉ will not be free to air on satellite unless the PSB channels of this country were totally redesigned and given a new remit, and/or a satellite is launched that only covers the island of Ireland. It's not going happen before 2012 anyway.

If Apartment dwellers are unable to recieve PSB channels there are three parties at fault

1) The developers/management company of the development for not providing a communal aerial (In the UK these are standard even in Local authority developments for Gawdsake)
2) The Government (National and Local) for allowing it
3) The residents for agreeing to move into such a dump

It should not be the responsibility of broadcasters (especially publically funded ones) to "bail out" these people by wasting money, energy, land and spectrum duplicating perfectly adequate transmission infrastructure. Remember "Public Service" = "Public Funded

I agree, in the current economic situation, the expenditure on this infill cannot be justified, the DTT Maghera signal on ch 48 is significantly stronger than the analogue Band 3 and UHF analogue signals and DTT isnt even on full power yet. Given that DTT signals are far more robust and less susceptible to multipath reception (i.e. ghosting on analogue) and that the minimum threshold for DTT is lower than analogue, the DTT infill is wasteful duplication.

But some of that logic could be applied to any sort of people who choose to build houses in valleys or suchlike. People need to live in some areas for whatever reason and many places will not match an ideal. Most places I've ever viewed let alone lived in would not allow any sort of external aerial and they did not provide a communal aerial distribution either, in Dublin 1 or 2 for example.

If quite a lot of people are in need in such service in an urban area, then the amount of License fee money they pay should justify some sort of relay especially if the network was initially built in an era of housing estates or terraced housing with planned reception based on 10 metre high aerials.

As already stated communal aerials are the norm in other countries so why not here ?

While the Government/Local authority planners are largely to blame individuals are nor entirely blameless either. If television is so important to people they need to give some thought to if theyre going to be able to enjoy it when choosing someplace to live. (You wouldnt move into a home without electricity or indoor plumbing for gawdsake) If enough people do this then it becomes a selling point and developers wont be able to get away with such nonsense (same goes for all those restrictions on satellite dishes)

Like I said, there simply is no choice no matter where I've looked in Dublin city. Developers simply assume that a cable subscription will be taken out as historically in Dublin cable takeup has always been very high. If there were some that offered an aerial connection then I'd regard it more favourably but there are no apartments that I've seen which have that.

Galway

Yes apartments should be wired for communal aerials and satellite as they are in the UK and most of the rest of Europe. Much more cost effective.

The intereference to Castlebar TG4 ch 23 analogue from Tonabrucy DTT ch 23 has been reported to RTÉ. They say if they get more reports they will look into the matter.

Also Castlebar DTT is co channel with BBC/ITV analogue at Brougher Mountain - fun times in Roscommon, Leitrim and Sligo are ahead!

Sorry to drag this topic (from June) back up, but it seems it is the right topic.

I'm located in Knocknacarra and was trying to receive the Tonabrucky base station yesterday. I got a signal on 2 frequencies, 490.000 Mhz (which is channel 23) and 690.000 Mhz (channel 48?), both fairly strong but neither having any active streams on the transponder. By the way this is inside an apartment with a PC dongle and a really small (10cm) antenna.

I'm just wondering if I have some settings wrong because I didn't see any channels, or if they have just been disabled because the service isn't officially live yet until the 31st of October. Has anyone else been able to receive it yet?

No, nothing. I get a carrier signal from the transponder but it doesn't see anything on it. It lists it as 'Empty'. Maybe I'll try it with some other software as well.

Edit: Oh thanks for letting me know about Maghera. I was wondering what was on Channel 48. I'm surprised I'm receiving a signal from there at all considering it's all the way in Clare and seems to be behind a few mountains as well. Tonabrocky is just around the corner from me.

Could you (or someone) confirm that there are actually streams being broadcast from those? I may be using the wrong channel grid.

DTT channel 23 from Tonabrucky has been switched off and the mux has now switched to channel 26. The DTT allocation to Tonabrucky is the same as analogue Castlebar and the DTT signal is reaching much further than intended. I am receiving at 82% signal strength some 23 miles from the tx site. The ch 23 tranmission were causing havoc with analogue TG4 from Castlebar which is co channel. Analogue Castlebar is received well outside the intended service area all the way down to Tuam and along the N17 as far as the outskirts of Galway City. These viewers for various reasons cannot get good signals from Maghera have had impaired reception on TG4 since th e DTT from Tonabrucky started. The only DTT channel allocated to Tonabrucky which isn't co channel with Castlebar analogue is ch. 26 (the unused TV3 analogue allocation for Cbar. The DTT from Castlebar is on Channel 22 is very strong at my location, 8m miles south of Tuam, > 40 db on meter. Both Tonabrucky DTT 23 and Castlebar 23 could be received together,combined two group aerials with a dual input masthead amp but I suspect there may have been some interference, hence the possible reason for the switch from channel 23 to 26 at Tonabrucky.

I am still receiving Channel 26 DTT from Tonabrucky this evening some 35 kilometres north of the tx site.
