10kw = Xdb
20kw = 2Xdb
40kw = 4Xdb
80kw = 8Xdb
100kw = 10Xdb
i.e. Each time the signal strength is increase by 3db you double its strength! As ex aerial installer I would say that an increase of 10db is a considerable increase!
The actual signal received at your aerial is dependant on a considerable number of variations. Therefore it is almost impossible to predict an accurate signal strength received at any one particular situation, but an aerial should be always mounted outside clear of any immediate obstructions for best results.

Hello Lynn
Your Satellite dish installer should be able to explain and answer all your questions. Your dish is able to receive any signal that are available from the the satellite that it is looking at. Assuming you are going to be using Astra satellite system at 28.2 degrees east you will be able to receive freesat ( run by BBC/ITV) The sky boxes( without card) will receive all free to air channels that are available via a sky box

Hello to all dab listners. I have been in discussion with powers at be in the BBC regarding coverage Radio Scotland on DAB. I afraid I have received no satifactorty answers. I tried to point out that Radio Scotland is not a Local radio station but attempting to cover the whole of the COUNTRY of Scotlad. The area that is covered by Radio Scotland is conciderable larger an area than the average BBC "local Radion Station" e.g Radio Leeds. This being the station that was used by the BBC in my discussions with them, obviously the correspondence did not know that Scotland is not part of England being the only country in the UK that has Local BBC stations.
Dab coverage of radio Scotland is very poor where it exists due the use by the BBC of commercial broadcaster using low power transmitters. In my correspondence I came to the conclusion that due the advice given to Offcom by the BBC, Radio Scotland, is treated as a Local Radio Station therefore it is not a "must carry" on DAB. This is despite the recent big push by thr BBC to listen on DAB.
One of the most annoying point about DAB radio coverage is that started before terrestrial Digital TV which now covers almost 95% of the land mass of the UK
Obviously the same problem will exist for BBC Radio Ulster and BBC Radio Wales

I am sorry to disagree with you,but I come back to the point that BBC radio Scotland is not a Local radio station in sense that e.g. BBC radio Leeds is. Radio Scotland is set up to cover the whole Scotland. I know that it is the case that the Multiplex that covers the whole of the U.K. must carry the the station that it does why not solve the proplem by adding into the multiplex BBC Radio Scotland, BBC Radio Wales & BBC radio Ulster. The listners can decide if they want to listen or not, but alas I will then be told that their is insuficient bandwidth. So why not have them carried on the Commercial national Multiplex,which appears to under used, problem solved.

Your comment regarding BBC Scotland. The opt outs of radio Scotland is for local consumption the same as e.g is for BBC Radio Leeds is for local consumption. The opt outs for radio Scotland could be done on FM and allow the BBC Scotland National Station to be broadcast on DAB. BBC Radio Scotland is not a Local Radio but is Broadcast troughout the whole of Scoland. So it should be carried on the the national multiplex matching the coverage of FM. If means it be broadcast along with BBC Radio Wales & BBC Radio Ulster throughout the UK so be it, the listner can decide if he/she wishes to listen or not.

As long as the tv has a hdmi socket for HD or a scart socket for normal digital tv it should be o.k. You will obviously rquire the correct connecting cables. When watching sky select the the appropriate input via your av button on the remote.

Hello, I note that there is references being made to possible changes being made some transmitters up to 2013. Is this for frequency changes or for power outputs or both?
Secondly I note that a considerable number of your correspondence are having problems in receiving the HD frequencies. Is Blackhill radiating the HD frequency (59) in the same pattern as the rest of channels or is that as I read somewhere that the signal is being beam at the main population areas e.g The cities?
