Outdoor/Indoor Aerial for DTT

logic

Outdoor Aerial were mostly required for picking up english channels, Irish channels were usually receivable via indoor aerials, is that correct? If so, will it be the same for DTT. What I'm asking is will I have to get an aerial mounted on the chimney just to pick up the irish channels.

To my knowledge and again posters like Watty would be more knowledgeable but the issue really is 1) terrain, hilly or flat and 2) the strength the signals are being broadcast from the transmitters.

With simulacasting of analogue and digital terrestrial at the moment DTT can't be at full power. Also Northern Ireland and Welsh analogue and digitial broadcasts necessitate lower broadcast power in those areas nearby. Therefor for now you may need an outdoor aerial but after 2012 an indoor one would suffice.

Also, I tested the trial box in Leitrim to pick up Freeview from NI. I didn't receive those. So that is because Freeview UK DTT from NI is set at lower power than analogue TT which can be received in leitrim through the chimney aerial. And that was tested with the outdoor aerial on the chimney and not an indoor one.

So its all about the broadcast power level and your distance away from a specific the transmitter nearest you giving the strongest signal and also whether a hill is or not beside you that affects your signal reception or not.

Someone living close to you ie a neighbour is where you could test what you can and can't receive.

A fallacy and the reason why so many people have very poor Analogue TV. In reality with a Chimney aerial Analogue RTE is better than RTE on cable and as good as RTE on Satellite (better before they went Widescreen).

Almost no-one in Limerick city, Galway City or North Dublin can get RTE perfect on an Indoor aerial. Some of the most cabled areas of South side Dublin in contrast can get a picture with a screwdriver stuck in aerial socket.

Basically an aerial outdoors that gives a perfect analogue picture is likely in most cases to work also for DTT.

It entirely depends on where you live and which way the window of the room with TV points if indoor or attic or outdoor aerial will work.

Tyrellstown and Limerick actually get much stronger DTT than Analogue. (Limerick Analogue is only 100W and the DTT will be 10kW, I suspect about 1kW now).

An outdoor aerial is always a better more reliable solution. Indoor aerial really only for temporary use or portable TVs. If you live in a an area where the indoor aerial is nearly OK, or OK at the window in another room, then an outdoor aerial in the attic may be a good compromise.

In Tyrrelstown one needs a pre-amp to get good signals - regardless of signal type (digital / analogue). Oh, and it is best that the aerial is outside, above the gutter line and pointing in the right direction (within 5 degrees).
