Full Freeview on the Divis (Northern Ireland) transmitter

niall burns: I have had a few thoughts:

Can you see the top of the tower (where the radiating antennas are situated) or are they obscured by Tollymore Forest? If they are behind the trees, then this could be a cause of poor . How did you fare for ? Was the picture changing such as during high winds? This might be an indication to the effects of the trees being in the path.

If you are receiving and Newcastle you will be unable to combine the feeds using a diplexer due to the that each transmitter uses. If you have the feeds combined using a splitter in reverse, then, whilst it can work, results can be unpredictable and could therefore be a source of poor reception on one or both transmitters - try removing it and tuning to Newcastle without Clermont Carn connected.

niall burns: In answer to your original question of whether from is possible, it isn't possible to provide an exact answer.

It might be worth looking around to see what others have done. In Dundrinne Gardens there are (November 2008) some Divis aerials.

It appears as if Slievenaslat and Castlewellan Forest might be the difficulty in your area, although this is just based on looking at a map.

UK Postcode Checker doesn't reckon Divis is a possibility, although such predictors are in no way infallible and it should therefore be taken with a pinch of salt.

It may be that reception is the best option. There are solutions that allow reception of and Saorsat using a larger and two LNBs. Can't really advise more than that; try searching the internet for information.

The picture was perfect. The picture never changed during high winds, the only time it did was during a thunderstorm. I might try to turn the towards to try. It couldn't really be any worse.

niall burns: You should confirm that you are tuned to by viewing the strength screen. On BBC One it should be tuned to , is and BBC One HD is .

Is it all three of these channels that are playing up?

Perhaps it could be a possibility (800W @ 3.7miles) that the signal level is too high going into your . This can appear as too little or too poor a signal:

If you have an then it might be worth trying removing or turning it down. Or you might need some attenuation (the opposite of amplification).

The former signals from Newcastle were at 1,000W each. The of digital signals to serve the same area are -7dB of the analogue which is 200W.

The power of the signals now are 800W each which is -1dB on the analogue. So in real terms the signal is stronger than the former analogue.

You might be able to build a crude attenuator (prior to getting a proper one) by connecting only the inner core of the lead by leaving the screen disconnected for a short distance (a few CM maybe). This will hopefully "loose" some signal.

Dave: At Niall's location the shouldn't be a problem post at his location (literally only a few miles from the transmitter site). Whether or not the photographs on streetview were taken in 2008, he still should have no problem with the PSB multplexes from this transmitter.

There are alos numerous properties with CC aerials so shouldn't be a problem either (i.e. he shouldn't need to faff around with Saorsat).

Nial: from the Newcastle transmitter should be near perfect at your location so I've no idea what's wrong. I'd check out all connections just to be sure a co ax plug hasn't come lose for example. Failing that I'd get somwone out just to see if there's something wrong outside (e.g. water ingress etc.}. You should be able to diplec CC and Newcastle at your location with no problems.

If is a no no I'd go for , as Dave suggests. Freesat combined with Saorview would ive you a pretty good choice of free to air , in my opinion. By all means have a go at Divis, but bear in mind there's always Feesat if it doesn't work out.

Peter Henderson: How can you diplex and CC as they are both C/D?

CC uses 52 and Newcastle uses 50, 55 and 59.

Well, whatever it is they're using as an alternaitive in Castlewellan Dave.

There definitely doesn't appear to be a problem either with or CC in the village, so they must be using something to combine the two. Certainly, there's no point in worrying about Saorsat if you can receive without any problems.

Unless Niall knows of someone getting in the area there's probably no point in putting up large aerials for Divis. This can work out quite expensive in the long run, believe me (I know this from experience). would would be the better option, in my opinion. OK, so there are 4 or 5 missing on Freesat that aren't on but, conversely, there is so much more on Feesat that's not on Freeview, so it's really horses for courses.

Castlewellan does seem to be a black spot for Divis, even with the increase at , for some reason.

hi. Im in Blackrock, Co.Louth, I got a 52 element group A hoping to pick up . When I try tuning in tv it doesnt find any . I am getting full or almost full strength but signal quailty is always at zero.
I am using a Wolsey Wfav 25 variable head amp. I have tried turning it down etc and still no joy.

Anyone any Ideas

RT coverage is not uniform across Northern Ireland; a few pockets can't receive it.

You are looking to see if you can receive either:

1. from one of the transmitters in the Republic (overspill), or;

2. A signal from one of the three RT transmitters in the North. These are intended to complement the coverage of the overspill.

I agree that you are going to be lucky to receive RT and, as such, will probably be best consulting with an installer.

The difficulty is obviously that you're in a valley.

I had a look at the centre of on Streetview (photos taken well before in March 2009) and quite a few houses have a UHF aerial on Strabane and a horizontally-polarised VHF aerial pointing roughly 90 degrees clockwise of Strabane. By my reckoning these are pointing to .

Prior to switchover, Ireland used VHF for some transmitters, including Truskmore:

TELEVISION FREQUENCY CHANNELS USED IN IRELAND

I'm not a professional so I wouldn't like to say whether those who could receive the VHF might be able to receive the current UHF Saorview signal.

However, as you're in a valley what can and can't be received might vary over a short distance.
