David Campbell: That's Clermont Carn!

722MHz is C52 and "RTENL 1" is the network ID of Saorview, the Republic's terrestrial television transmitter network.

The NI Mux (aka NI Mini-mux/NIMM) which is broadcast from Carnmoney Hill carries only RT One, RT Two and TG4.


Freeview standard definition signals use the DVB-T format. Freeview HD signals use DVB-T2. The NI Mux uses DVB-T2 even though pictures are in standard definition, hence a Freeview HD receiver is needed to pick it up.

Saorview uses DVB-T hence a Freeview standard definition only receiver can probably receive it. However, the pictures carried on the Saorview signal are encoded using MPEG4. Freeview standard definition pictures are encoded with the earlier MPEG2 format and hence many non-Freeview HD receivers don't have the capability to resolve MPEG4 pictures. Evidently you are lucky and yours does.

So not only do you not need a Freeview HD receiver to watch the Republic's channels, but you can receive the full complement of Saorview services rather than the three carried on the NI Mux.

Winter Hill (Bolton, England) transmitter

g allonby: The message isn't "from" Home : HyndburnWindFarm, that is a link to the Hyndburn Wind Farm's website!

Can you not receive from Pendle Forest which would give you all the channels?

It might be a good idea to retain your Winter Hill aerial, particularly if some channels are OK.

If it is mainly those channels which are available from Haslingden (the PSBs), then you could combine an aerial on Haslingden with the Winter Hill one using a diplexer:

A C38 split will probably do.

Receive HD from Haslingden and the rest from Winter Hill.

Louise Baker: See the page for Stockland Hill. On it there are postings from "Transmitter engineering" which are automated and taken from BBC where they end with [BBC].

The reports are "very weak signal" for HD.

The BBC only reports on its own channels although it doesn't mention standard definition.

If your TV is tuned correctly (to Stockland Hill), then retuning will yield no positive improvement, the only possibility is negative whereby you loose some services.

Sam D: Royal Mail lists 47 addresses within that postcode. On Google I can see a tower block and that is it.

If you are using a communal aerial system, then if it is that which is at fault, then you need to notify whoever is responsible which might be your landlord.

If neighbours are also affected, then this obviously adds considerable weight to this being a possibility.

It may be that only some neighbours are affected.

Kevin : No maintenance work that we know of.

Try a manual tune on UHF channel 47 if your receiver allows manual tuning.

Or maybe your aerial needs aligning better.

Dave F-P: Terrain plot between you and Wenvoe:

It appears that Cefn Eglwysilan is in the way, about 200m above your ground level!

Les Waters: The most common answer to this sort of question is that the TV does not have a DVB-T2 tuner in which is the format HD signals use. Standard definition pictures in the UK are broadcast using DVB-T.

What is the model number? We can check the specifications.

Marc S: Because there are far fewer ITV1 HD regions than there are ITV1 regions and sub-regions:

Les Waters: It appears that this model does not contain a DVB-T2 tuner.

The user manual is here:

The only mention of "DVB" is on page 2 under the heading "Digital TV Notice". No mention is made of DVB-T2 - only DVB-T does. It states that the set meets the standards of DVB-T as at August 2008.

According to Wikipedia, DVB-T2 prototype tuners were demonstrated in September 2008, so therefore DVB-T2 didn't exist (or certainly wasn't finalised) when the TV was designed.

Chris: It is those who receive from the Whitehead relay transmitter who will never receive any of the COM channels. See here for an explanation:

If you received one of the COMs momentarily, presumably from Divis, with your aerial vertical whereas Divis is horizontally polarised, then maybe this might be an indication that an aerial on Divis will bring in all channels. Then again, it may be intermittant. You will be best advised to consult an installer. Also, look around to see if others have new Divis aerials.

If you are looking at DIYing it, then a Group A aerial (if it's a yagi type) will be best; don't get a wideband yagi as these aren't as effective on the channels used by Divis:
