RTE one HD sensitive reception

jimmycrackcorm

I have an indoor aerial and live in west Dublin. I can get all the channels on Saorview very clearly but RTE one HD is the only one that is difficult to get right.

Basically, it is very easy to point towards Three Rock and get everything bar RTE one but I need to adjust the aerial to get RTE one and then I only get some of the others.

My question is really why is this one channel not lining up?

Short Answer is your signal is marginal for Mux 1.

Longer answer is that indoor aerials are subject all kinds of RFi. Some Indoor aerials are so badly screened that mobile phones/wifi/etc can intefer with the ability to watch DVB-T in a stable manner.

Add to that the bitrate error might be more sensitive in some tuners trying to pull in high bit rate data rate ie HD vs SD.

Have your indoor aerial as far away as possible from these devices. If that means extensing the cable to get the aerial to a window, do it.

It won't be the only channel, you'll have problems with RTE1 +1, RTE jr., & that be3 if it's still there.

With indoor aerials especially, it mightn't always be possible to find a single position where you get a decent signal on all frequencies, due to reflections, obstructions etc. As mentioned already, near a window facing the transmitter would usually be your best bet.

for my tuppence worth, i found the one for all brand to be the best when it comes to indoor aerials

Don't get me started...

One For One are generic antennas that take signal and noise from all over the band(s) (I've taken some apart and they were only a wire covered by fancyful inert plastic shapes.

In the UK that makes some sort of sense due to the large number of Muxes. Here in Ireland we have TWO frequencies. Ideally you should be buying aerials of the GROUP / Colour Code that matches both of your local transmitters frequencies.


The best generic indoor one I've found so far was for a tenner in Lidl (or Aldi)

If you can't install outdoors try a attic aerial pointing the right way. Just make sure there's isn't any foil insulation blocking it's path.

^^^^^^^^^^^

well, ive used various makes of indoor aerials and the one for all brand was the only one that tuned in all the saorview channels

as for putting an aerial in an attic thats a waste of time from the get go foil insulation or not

Waste of time for who? And why?

Obviously it might be considered a waste if you have acceptable reception from a set-top aerial in the room with the TV: is this what you have in mind?

i tried putting an aerial (high gain) in an attic couldn't get quality above 30% picture kept breaking up...did the same at my neighbours house with same result

I've got an aerial in my attic, the wrong group to boot (long story!), pointed at Three Rock and get 100% signal/100% quality. On top of that it's pointed at the dividing wall between us and our neighbour's half of a semi-D bungalow.

Without knowing anything about signal conditions in those attics, or about your installation skills, that proves nothing.

Generally speaking, where aerial location is concerned, higher is better.

STB.

And no doubt the one for all aerial itself has no independent power so long cable runs will not help it. If it powered there is no reason not to extend the cable run into the attic. It will perform better without a doubt and will not be subject to nearby interference.

But the first thing anyone using an indoor aerial is that it doesnt work sitting on the TV. It has to be near a window preferably facing the transmitter location.

Ah, but it's a special DIGITAL aerial......:rolleyes:

What kind of high gain antenna? Which group and what dB gain? Which channels were the muxes on?

Antenna

Its possible that there are signals from two transmitters involved ? (3Rock and Kippure) and the OP (in west Dublin) might have originally tuned in with one MUX from one transmitter and the other MUX from the other.
If unsure about which one is actually tuned in for each MUX and which one should be the strongest, do another retune scan each time after moving about the aerial.

Same with me - the MUX1 channels are unwatchable MUX2 are all fine, now I only have a very basic antenna at ground level so problems are hardly a shock but why is MUX1 so poor compared to MUX2? I'm in Waterford city.

Mux 2 probably isn't good either, just 'good enough'.
