IanF:

But still many people do not get to use mobile phones at home because of poor signal coverage away from towns. Many rural communities only get very slow broadband, often too slow for streaming SD programmes, let alone get HD or UHD. Even in some urban areas the mobile signal is so poor it is hard or impossible to use. Where I live, on the edge of a county town, a mobile is unusable except in one room upstairs! Such is the lack of good signal coverage by the mobile providers.

Further, many people prefer to use a 'traditional' phone service rather than a mobile and BT are planning to continue providing such a service, but using VoIP rather than copper/aluminium wires as at present.

It is always the case that some pundits predict things will happen, but they are always over optimistic with whether it is viable or with the timing.

COM 7 and 8 are temporary services on 30 main transmitters only. There are no plans to extend the coverage at present. However, future changes to the transmission scheme will probably see the services carried on COM 7 and COM 8 being included in other multiplexes as they are changed from DVB-T encoding into DVB-T2 coding, which can carry more information but requires a TV capable of both receiving these transmissions and displaying them in HD when provided.

Alexa:

The change happened before June 2018 and was widely reported in the media in that area. Up until the change, a Group A aerial was correct. As COM 7 and COM 8 are now on channels 55 and 56 respectively, a Group A aerial will not give satisfactory reception of those, so a wideband aerial is now required. A Group A aerial is fine for channels 21 to 35 but not above that.

If you go to http://www.digitaluk.co.uk/coveragechecker/main/index/dummy/NA/yes and put in your full post code and house number, you will be shown the current arrangements as well as the future plans for further changes. If you have a wideband aerial fitted now it will be suitabkle for all changes foreseen in the future.

Christian Bailey:

This is not the website for London Live, http://www.londonlive.co.uk/. You would better ask them your question.

This website is independent of all broadcasters and is aimed primarily at assisting viewers/listeners having reception problems.

Steve:

You may also want to consider mounting the aerial away from the house so it can 'see' past the tree. I had a customer with just that problem and by erecting a slim, but fairly rigid, lattice mast in one corner of the garden, the aerial could easily 'see' past the tree. (Do check the planning rules with your local council though.) The coaxial cables used must be of very good quality and be run where it does not create any risks of being caught up by people or machinery (lawn mower?), etc. Consider running it along a wall or fence perhaps? You should avoid having any joins in the external run so that rain water cannot enter the cables.

Deborah Grinnell:

The regional services are still broadcast by Freeview an the SD multiplexes relevant to your local transmitter. The HD services do not carry the regional services at present.

Living in West Wiltshire, we get our Freeview from Mendip and BBC1 West is available as normal.

Vincent:

The Care Home is responsible for the communal aerail on the home. Contact them and ask them to ensure that your mother is getting the TV signals she should. Also, put the post code of the home into the Digital UK coverage checker website at http://www.digitaluk.co.uk/coveragechecker/main/index/dummy/NA/yes. That will tell you which channels are being used so you can check that her TV is correctly tuned (the channels in use are usually shown on the manual tuning page - but do not do a retune unless it is clear it is tuned to the wrong channels.

John:

Further to that said by StevensOnln1, pust your full post code into the Digital UK Coverage Checker website at http://www.digitaluk.co.uk/coveragechecker/main/index/dummy/NA/yes. That will show you the current channels used by the recommended transmitter and the planned future changes expected over the next few years. It will also advise on wheteh an aerial change might be needed.

DJB:

Aerials are usually 'grouped' to receive a restricted range of channels, unless you have a wideband aerial already. So turning the aerial may actually make matter worse as the current aerial may not suit the alternative transmitter and you could lose more channels.
