Best aerial , Mt. Leinster

Slates

What would be the best aerial to get for DTT and analogue reception from the Mt.Leinster mast??

Any help would be welcome

A group B unix 52

Where are you located? It won't work in Tokyo or sheffield for instance..
(Always say where you are when you make an aerial request)

North Kilkenny, direct line of sight to the mast.

unix as above then will do the job.
Mount it outside on a gable end with that line of sight or on a chimney for best results.
You won't need an amp.

cmac

Any recommendations for on-line suppliers of this aerial (and other above-contract grade aerials)?

Unix 52 is overkill if you've line of sight. Especially with much of north Kilkenny up on a height. I'd try with a contract Group B first.

I can point to many posts here with reception problems with a line of sight to mt leinster such is the disaster of their need to keep power low due to preseli wales.
unix 52 is most certainly not overkill.

Overkill I would agree with.

Infact the OP wants both an aerial that does analogue and DTT - thats one aerial that does Group A and B combined. If thats the case he really should be looking at a Wideband especially with line of sight.

What aerial would you suggest ?

Ah for heavens sake,you definitely won't need a wideband for uhf analogue from mt leinster if you have line of sight.
A group B with line of sight will have no problem with the uhf analogues for the short time that they will remain on air.
Up in wicklow a group B pointed the wrong way gets them fine.
In fact I don't have a line of sight and get good tv3 and tg4 mt leinster with a grid vertically polarised pointed at Arklow with no amp.

Tv3 and TG4 mt leinster are very very strong unlike dtt from there.

Find me a post that says they've got problems with Welsh interference from the Castlecomer Plateau or anywhere in north Kilkenny. It's nonsense to say that a welsh signal from over 100 miles away, 40 or so of which is over land, will override a signal from a main transmitter that is 10-20 miles away, the very hills on which Mt. Leinster stands blocking any signal from Wales too. Tropospheric ducting will happen irrespective of aerial type. North Kilkenny has variable terrain but if the OP has line of sight, there will be no point in using a Unix 52 and the extra wind loading and stronger poles etc to use such an aerial.

The group B contract will perform pretty much as well as a wideband on Group A, perhaps not so much on Ch 23 and 26 though. A cheap log periodic like the one on http://cpcireland.farnell.com/ might also be a good option.

As far as signal strength goes, sooner or later powers on all the main sites are being increased. I don't think there is much point on splashing out on what is a temporary problem for those away from Welsh interference.

I didn't say the problem was welsh interference in this case,theres a recent post reporting bad reception in south kilkenny in the sticky thread.
I said the problem was lower power on ch 45 because they don't want to cause interference in wales.

Also what are we talking about here,at most €30 or €40 for a sturdy aerial as opposed to a piece of tin that the contract is.
If Slates wants cheaper,a grid can be got for less than that.
Both are far better than a contract.

Theres no need for a long debate about it.

lucernarian

Indeed there's no need for a debate, the Unix 52 is overkill and it is as simple as that for this particular case. Also, I've seen more than a few Unix 52s with missing X elements around places like Swords and Dundalk where they seem to be popular. That could be installer-caused I suppose. Finally grid aerials and Unix 52s have similar wind loadings and having an aerial that needs extra support and/or puts extra stress on a chimney shouldn't be used unless necessary. A contract fitted with a dipole and good cabling can last a long time, some contracts appear to be much better than others from what I can see on some of the online shops.

STB

You can for heavens sake all you want. RTE's recommendation for combined analogue and dtt reception is clear for Mt Leinster, Spur Hill and Three Rock.

@slates

Is this the same RTE that recommended group A's for mt leinster up untill recently?
I would ignore their advice to be honest and go with whats practical.
A wide band will only ever be needed after digital switch over at mt leinster if theres commercial dtt which is why they are recomending wideband.
We both know that isn't going to happen ever because with the proliferation of fta satelite,theres noone going to pay a subscription for it.
Theres plenty of posts on that here,just ask watty.

@ To be confirmed.I've never seen wind loading on a unix 52 to be a problem.
You could have a swarm of crows nearby alright I suppose but again,I'd rather they sat on something sturdier than a contract aerial.
Saying a grid aerial [which can sit on a thin 3 ft pole] puts stress on a chimney is nonsense frankly.
Theres hundreds of them round me for decades and I've not seen a chimney fall yet.
I'd rather you wouldn't invent problems that don't exist with all due respect.

@slates

Before stb gets heart failure,I'll recommend a grid aerial for you.
They are cheap and cheerfull,sturdy and cover all bases..even bases you'll never need to cover in my opinion.
The unix 52 is what I'd put in myself there.

STB

RTE's recommendation on what to use is per that sheet which has being doing the rounds for over a year. It clearly recommends A for Analogue only and B for DTT only, Wideband for both combined.

Look Black Briar with all due respect to amateur hobbyists, Channel 23 and 26 analogue and Channel 45 DTT in one combined aerial is best served by a wideband aerial, not an A, not a B group aerial as stuff will be out of band otherwise.

You dont have to be an aerial hobbyist or a telecommunications engineer to work that out.

Lets get people putting up the right gear and stop with the bickering.

Given that analogue is going off at the end of next year,I wouldn't bother getting an aerial for it especially now when all channels are on saorview though and besides,you won't lose analogue tv3 and tg4 with a group B,it won't be as good as on an A but it will be perfectly fine.
RTE's recommendation is out of date given there won't be any services to merit using the group A frequencies after analogue switch off.
In that regard recommending a wideband [although I accept the irony that one of my solutions,the grid is a wideband] over a group B is similar to recommending a VHF aerial is added too...it's unnecessary if Slates has everything they want on saorview.


I'm not bickering,I'm just disagree'ing with you and explaining why so lets agree to disagree if a reasonable discussion is not possible.

St Senan

Indeed a Unix 52 will be an overkill for the OP. Given his location and his direct line of sight to the Mast all he needs is a Wideband.
It's happening a lot lately on these threads with amateur hobbyists who are not on the road day to day or on chimneys installing Aerial's and Satellite dishes. All they are doing is knocking any proper advise that's being given to people from installers who post here.

marclt

Right lads, enough!

OP, if you have any further questions - don't be afraid to ask!

FRIENDO

I have a good class 2 wide band aerial which at the moment is picking up Wales Freeview. In the past I had it pointed at Mt Lenister and could get Channel 39 with low signal and quality approx 20%. When it moved to Ch 45 I could not get Mt Lenister due to Co channel inteference.

Question ?
Would it be worth trying a Unix 52

Gorey may also be an option approx 11km as the crow travels (no luck with wideband)

Thanks

To answer that question and the problem you are having in Camolin would be to ask your local installer's.
Noel Bergin or Aidan Doyle both based in Camolin area.

Your problem with mt leinster is different friendo in that you are in a strong preseli area so will always lose mt leinster during skips regardless of what aerial you use and won't get it at all combining with a welsh aerial

You need a line of sight towards the cemetary in Gorey,near tesco.

The arklow tx works out as far as coolgreaney to it's west that I know of but also gets through high ground to there so these low power tx's may be stronger than people think.

Can you see forth mtn at all? I'm sending you a pm

FRIENDO

Thanks BB,
No I cant see Forth at all. Living in the Shrule/Ballyduff area shadowed by hill west, north/west and south.

Ah I can picture your difficulty now.
You could do with a very good aerial installer with a meter who would try all out for you.

Saorsat isn't untill next may at the earliest.

That wideband aerial.

Do you have it pointing the right way ? You have it pointing at Wales dont you ?

Mt Leinster (45H)
Gorey (Ch55H)
Forth Mountain (Ch52V)

Move your aerial position to either Mt Leinster. In Camolin this should not be an issue - Mt Leinster is first choice, then Gorey.

Pointing at Wales now.
When I point the aerial to Mt Lenister (45H) I get nothing.
Will try both Gorey 55H and Forth 52V again in morning (map and compass reference), I think it will be a long shot.

Not living in Camolin and none of my neighbours are getting Irish Dtt.

Thank you.

As for recommendations of where to buy, I've used CPC in the past and found them to be cheap and fast.

FRIENDO

No luck with Gorey, Forth or Mt Lenister.
However even with the aerial lying on the ground it was still bringing in good Wales freeview.

Sorry about delay in getting back (bad weather and shift work).

STB

Do you mind me asking where you are then ?

Are you on the coast ? Blackwater ?

Living in Shrule/Ballyduff area, shadowed by Sliabh Bui.
Presently served by Monasootagh Relay which will be decommissioned in 2012.

Peter Rhea

Don't know that part of the country too well but looking at a map, Forth Mountain seems to have the clearest signal path.
I don't know what power it uses though, or how it would fare over the 24 odd miles to your location.

Well the fact that you are using the Monasootagh Relay for analogue which is a small fill in, then its definitely Forth Mountain Channel 52 Aerial pointing South with vertical polarisation for DTT.

24 miles does seem an awfull long way for forth,but if you can get it,it would be the dogs bollix as you could have saorview and freeview all on one epg if you get a group B or a cd aerial for forth.
Thats basically the multiroom I have except using the arklow tx for saorview.
In this case you'd want a pretty good 2nd aerial.
I'd imagine Mylie is your man to test that out for you.
Best of luck and let us know how you get on.

FRIENDO

Picked up Forth today with the aid of a meter.:)
Thanks for all your help (BB, STB and all others)

Signal a bit low but picture and sound working loud and clear today (saorview).
Wales freeview also coming in on a smaller aerial.
Fingers crossed all works out.

Thanks again for your help.

Per Mpeg4Ireland site I'm approx 40km/25 miles, 192 degrees SSW to Forth.

Can somebody tell me if the transmitter on Forth Mountain transmitts to an area 360 degrees around it or is it only to the south of forth mountain. I know someone who is having difficulty picking up Saorview in the Ferrycarrig area at the moment and I was wondering if that is the issue.

Peter Rhea

The Saorview coverage map shows that area as being covered by Forth.

The maps show me where the transmitters are. However if I click on a location north of Forth Mountain it recommends mount Leinster and if I click south of the mountain it recommends Forth Mountain. This is what make me think the transmitter is only transmitting 180 degrees rather that 360 degrees.

Peter Rhea

If I type "Ferrycarrig, Wexford" into the coverage map search bar it gives me a location to the NE of Forth & NW of Wexford town. Moving the location icon will find spots where Forth is the recommended site & some where Mt. Leinster is, within a small area.

If you're having trouble with one, try the other but you'll have to wait until next October for Mt. Leinster's Welsh interference problem to be sorted out.

wextipp

Thanks.
It may be down to Welsh interferance. I'll check it out a bit more.

I live North of Forth Mountain. As I said in previous post, I live approx 40km from Forth, Forth would be approx 192 degrees from my loction.
You would have to put your UHF aerial vertical and you may need to change to a wideband aerial if you do not already have one.
Going to Forth should eliminate any inteference from Wales as Forth is on 52V. Combining Wales and Forth may be a problem for some.

I find the Saorview map has changed, in the past Forth coverage would be recommended for my location, now it only recommends Mth Lenister leaving my location in white.

Ok, that confirms then that Forth Mtn is broadcasting in that direction as well. The interactive map confused me a bit when it was suggesting using Mnt Leinster for all points north of Forth Mth even if the point was closer to Forth Mtn.

STB

Ferrycarrig is too low down for Forth Mountain.

I am not a million miles away. Mt Leinster on Ch 45.

Pointing your aerial towards Wales will cause you problems.

Forth Mountain being received with a loft aerial in Ballymurn, in an effort to deal with co-channel interference, and mixed with the other mux's from Preselli.
After a.s.o interference won't be a problem and the loft aerial probably removed.
