Hello
Maybe you can help me.
I live in LLanelli SA15 3BP and I cant pick up all the Freeview Channels.
I have a digital Tv with built in freeview and I have gone into SETUP many times and re-installed but I can only get 1,2,3,4,5,6,7,8,9,13,14,33
These are all the tv channels I can pick up. I am on a loft aerial and have used a booster but still nothing more. I would be grateful if you can let me know why I cant get all the freeview channels.
thank you

Val Grace: The Llanelli transmitter, which is to the north of the town on Ty-du Hill, only carries Public Service channels, which is what you've got. This is because the Commercial broadcasters only wish to spend money on transmitting from 80 or so sites nationwide, missing out 1000 or so small sites like Llanelli. For a further explanation, see here:
Will there ever be more services on the Freeview Light transmitters? | ukfree.tv - independent free digital TV advice
In order to get the full service, your aerial will have to point at Kilvey Hill in Swansea. Loft aerials, by their very nature, get less signal than if they were outside, but in some cases that is sufficient. You have found that you get sufficient signal from Llanelli.
However, you may (or may not) be so lucky turning your aerial to Kilvey. Looking at Google Streetview there are quite a few aerials on Kilvey. But the direction to it is inline with the terraces, so a loft aerial is almost certainly out for it due to that fact.

Hi there. I hope you can help me. I live in sa15 1nn down the bottom of the hill and my tv signal is terrible. Only channels 1-5 work well. All the other channels are un watchable. I called a guy out and he claimed I should be getting a decent signal.
Please advise.
Thank you

Adam Rodriguez: I wonder if the guy may be right if your aerial is pointing at the Llanelli transmitter which carries Public Service channels only.
Refer to this page for services by multiplex (those with a bullet in the "W" for Wales column apply):
DTG :: DTT Services by Multiplex
There are six multiplexes, each of which is a single signal which carries multiple services. In summary there is:
PSB1/BBCA | BBC One, BBC Two etc
PSB2/D3&4 | ITV1, ITV2, S4C, Channel 4, Channel 5 etc
PSB3/BBCB | BBC One HD, BBC HD, ITV1HD, S4C Clirlun
COM4/SDN | ITV3, QVC, bid etc
COM5/ArqA | Pick TV, Dave, Really etc
COM6/ArqB | Yesterday, Film4, 4Music etc
The Public Service Broadcaster (PSB) channels are carried by all transmitters. The Commercial ones (COM) are only carried by the main transmitters and large relays. This means that there is a portion of the population that is unable to receive the COMs (some of which may have them intermittantly).
You say that you have logical channel numbers 1 to 5 which means that you must be receiving PSB1 and PSB2. If your set isn't a HD one, then you won't be able to receive PSB3 even though it is available. I conclude that it is the COMs only which you are having difficulty with. Is this correct?
You've posted on the page for the Llanelli transmitter and it is PSB-only. So if your aerial points at it, then you are receiving what it broadcasts and therefore the gentleman is quite correct. From your location the Llanelli transmitter is north and your aerial will be vertical (elements up/down).
If your aerial points to Llanelli and the TV has tuned in the COMs, then these must be coming from another transmitter which is likely to be in another direction to which the aerial faces and so this is liable to result in poor reception (of those channels). Based on the Digital UK predictor, I wonder if it is the case that your aerial is on Llanelli, that the COMs your receiver has tuned in are those of Kilvey Hill which is a full-Freeview transmitter and is also vertically polarised.
Or if your aerial points to Wenvoe (a bit clockwise of east, aerial horizontal), then this is also a full-Freeview transmitter, but its COMs broadcast on the same channels/frequencies as the three PSBs from Llanelli, so you may find that reception of the COMs is wiped out thanks to that.
Or you "may" be able to receive a full service from Carmel which is clockwise of north, with your aerial horizontal.
Find out which transmitter(s) your receiver is tuned to for each multiplex by viewing the signal strength screen whilst on one of the services.
Those that "may" be available to you are:
- Llanelli: PSB1=C49, PSB2=C45, PSB3=C42
- Kilvey Hill: PSB1=C23, PSB2=C26, PSB3=C29, COM4=C25, COM5=C22, COM6=C28
- Wenvoe: PSB1=C41, PSB2=C44, PSB3=C47, COM4=C42*, COM5=C45*, COM6=C49*
- Carmel: PSB1=C60, PSB2=C53, PSB3=C57, COM4=C54, COM5=C58, COM6=C61
* Wenvoe's COMs co-channel with Llanelli's PSBs.
For example, tune to ITV3 and bring up the signal strength screen. ITV3 is carried on COM4, so if it says that it is tuned to UHF channel 25 then it is coming from Kilvey Hill.
There is no guarantee that you can receive from any of the other transmitters. Even reception of the COMs off-beam of the aerial isn't forced to mean that an aerial pointing in the correct direction will result in reliable reception of those channels.
My money is on your aerial being on Llanelli and the three COMs being tuned to Kilvey Hill.
