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.
