List of Transposers/Relays upgraded to DTT?

Mayo Exile · 2010-07-21 21:11:43

I was enquiring to RTE/RTENL about when the Castlebar relay would be upgraded to DTT and got the following response from RTÉ Network Support: Thought it might be an idea to keep a list of these (due 31/10/2010) in one place and posters in different areas of the country could then post if and when DTT begins from these…

Gone walkabout for sure since the days of the 53 .

Or 190 or 145...

I'm still baffled as to why there is not an Infrastructure Grant.

I had Belmullet/Dooncarton/Iorras and Achill earlier. Must have deleted them somehow
Aranmore I had,

Forgot Monaghan had been mentioned.

Updated http://www.techtir.ie/tv-radio/Irish-DTT-Sites

So now we have 47.

Wasn't there a suggestion from someplace that "really" there would be 48 or 49 sites?

(maybe Divis and Strabane are 50 & 51 )

(I'll not update this (all sites) http://www.saortv.info/terrestrial-saorview/tuning-saorview/ or this (active sites) http://www.saortv.info/terrestrial-saorview/transmitters/ yet.

Conor Hayes, in his presentation to the Oireachtas committee said 49 sites would be ready by launch next year with a further 2 by late 2012.

The final figure may depend on the extent of coverage from the existing transmitters e.g. Mullaghanish was planned, in 2008, to go from approx 40kW to 200 kW at ASO in 2012.

Couple of significant mast extensions have been mooted, Maghera is one such.

This may eliminate the Loughrea transmitter which was tendered for in the same batch as most of the ones done this year and since which I have heard nothing about it. I wonder if it also affected plans for the Kilduff mast ...which was a mooted 'new' Main Transmitter from the late 1990s DTT plan. The new Maghera mast will be 160m as against the older 147.5m mast.

The old Maghera mast has combined Analogue/DTT UHF panels at c.133m-143m, the new one will have DTT only UHF panels between c.143m and 157m

But for now all I know is that Eamon Ryan lied back in May to Liz McManus.....again

Glanmire Co. Cork? Never heard of one here either.

So I'm a slight bit confused.

Watty, if this list is being updated again, could the UHF channel (where known) for DTT also be included with the transmiter?

Glanmire DTT on air since a few weeks ago was reported by another poster, but no mention of UHF channel in the post. Glanmire 'Saorview' is Ch 47 (682MHz) and H polarisation.
47 is its never used TV3 analogue channel BTW.

The mast known as Dooncarton/Iorras/Belmullet ( all three names are used) is here , beside the Radar.

Photo taken last week with the tower(s) and radar to the north of the camera, can anyone spot anything ???

What are supposed to be looking for?

The skinnier mast looks like it might have UHF TV aerials in a Housing on the tip.

It has a lot of Mobile phone aerials and Microwave links.

on Google Earth it looks like there is only one mast

Single Mast shadow.

Definitely two on photo

Watty, no detail for Crosshaven Co. Cork on your list - Saorview is on air from there on Ch46 (674MHz) and Vertical.

Also what is listed as "Ferrypoint" - Monatrea, Co. Waterford is on air - its on Ch47 (682MHz) and Vertical. It mainly covers Youghal area, Co. Cork (across the water from it).

(Ferrypoint isn't the most accurate name - that place is almost at sea level !, the transmitter is on nearby high ground)

Thanks The Cush. I was missing Clonmel I think.

The Lugad/Monaghan channels in http://www.boards.ie/vbulletin/showpost.php?p=68980375&postcount=1 may not apply to DTT?

It's UHF 55 horizontal for now anyway.
The 2nd tx referred to in that thread (Monaghan NW) doesn't exist but it's in this list; http://www.wolfbane.com/articles/eitv.htm

Final confirmed list of DTT sites from Official RTE Brochure (preview) at ISAA meeting, presentation by Ray Maguire.

The are no corrections other than adding channels.

The Brochure has coverage maps and only channel list for one Mux.

I find it strange that Knockanore/Cnoc An Óir made it into the final list. There's no analogue (currently FM only, went live around '98/99) from that site so no current UHF aerials would be pointed towards it. But I suppose it would have the potential to replace smaller relays such as Listowel and maybe Abbeyfeale.

I see that two of the TX sites (Dooncarton and Bantry) are listed as H&V polarisation. Bit unusual for television, no? Or is it that it's V in one direction and H in another?

H & V in different directions isn't too uncommon,

But if in the same direction it is slant -45 or +45, if the H & V are in phase, and it's circular Left hand or right hand if there is 90 phase difference (which is lagging sets the "handedness". So I guess it's different directions.

Normally only Mobile applications need Slant or Circular Polarisation.

I'd say there's some here who would be happy with the removal of the Navan and Drogheda relays, since the channel plan for both was co-channel with Divis.

Navan was co-channel with Brougher Mountain, depending on what channels were used by Navan out of 22, 25, 28 and 32. Navan was allocated another 4 I think, but like 30 and 34 for Mt. Leinster, those extra 4 channels were not to be used in the near future. I don't know what site was proposed for the Navan relay. I would have said that the likes of the Arklow relay wasn't very necessary barring the fiasco with frequency planning along the southeast coast.

Out of the two Drogheda was probably more necessary due to the local topography and population densities (quite a lot more apartments in poor reception areas in Drog) but the frequency allocation would result in Freeview reception difficulties. Not as bad as what happened with Mt. Leinster/Preseli at least.

Ah ok, I stand corrected so!

As I'm in Listowel at the moment I was looking at the situation here. Despite having LOS to Knockanore the coverage checker is recommending Knockmoyle instead (I know Knockanore is not online yet but it is being recommended for other parts such as in the town itself). Plus I can also get Mullaghanish and Maghera here, leaving me with 4 potential sites, a far cry from analogue where only Mullaghanish VHF can be received without snow and it's ghosted.

Setting up a combo box for a friend of the family on Monday, will be curious to see how that goes.

From my layman point of view is there ANY difference between main and relay/transposer sites e.g. quality of signal etc? thanks.
