For further information see our DAB installation guide. It is important to check the cables and the aerial for damage and that they are operating correctly. Make sure any cables between your radio equipment and aerial are connected securely. Our DAB installation guide provides further information. If your radio displays signal strength, use this as a guide to ensure the best position. Unfortunately, some radios are less sensitive than others and need careful positioning to work reliably. Many Digital radios have a signal strength display which enables you to position the Radio for the best reception (usually a number of blocks) as a guide of reception quality. Even in good areas an external aerial will guarantee optimum performance and will also ensure consistent listening quality. If your radio reception is poor then you could consider an external aerial for best reception quality. In most circumstances the supplied telescopic aerial should be perfectly adequate, and as a rule of thumb DAB aerials tend to work best when vertical and extended at least 35 cm. Try moving the radio around to see if you can find a better position where you get good reception of all the stations you want to listen to. Further information on tuning your DAB radio can be found by visiting the Get Digital site or see our DAB tuning guide.Įnsure the telescopic/integrated aerial is fully extended.

If this does not work, a full re-scan might be needed. Check your radio manual for specific instructions on doing a full re-scan. Try switching your radio on and off. If you still have a problem use the ‘autotune' function to re-tune. Nations and Local radio services are carried on a mix of commercial multiplexes. BBC Radio 1, BBC Radio 4 are grouped together in a single multiplex. It will also show you any transmitter faults. Currently it reports on network DAB stations only Local and Nations radio faults are not included.Ĭheck whether there are any known works or warnings that might be causing the problem.ĭAB uses multiplexes to group services together. The BBC network stations, e.g.
The CAI ( Confederation of Aerial Industries ) is a recognised trade body which will can put you in touch with one of their members in your area.īy using our Transmitter Checker, you can check which DAB radio services are available at your location. The BBC cannot recommend individual Installers. We advise you check that your antenna is able to receive DAB, in the majority of cases you will need a new antenna. An exception is "helically wound" FM aerials. It is important to minimise the loss by using good quality cable and connectors.ĭAB uses different frequencies from FM radio. If you have an external aerial, a radio signal will always lose some of its strength as it passes along the cable and through the connectors. Ideally, this should be on the roof or high up on the outside of the building, though it may also give good results in the loft. An indoor aerial may be good enough, but for the best reception use an outdoor one.

DAB aerials are different from FM or TV aerials, so you need a good quality DAB-specific aerial.

Broken aerials may affect reception.Īn externally mounted aerial can be attached to many types of DAB portable radio and hi-fi systems. Tilting and swivelling the aerial will help to get the best signal. Telescopic aerials on portable radios should be fully extended to receive a good signal.
From time to time radios should be re-tuned in order to discover new stations. Most DAB radios come with built in signal strength meters which can be helpful. Portable radios should be tuned in a location in your home where the best possible signal is received. Most DAB radios can be tuned easily at the touch of a button. If you live in a basement flat, or your building is steel-framed or reinforced concrete, coverage may be affected. Have a look at our Transmitter Checkerto see what BBC services you can receive where you are. Your radio must be in a good DAB coverage area to receive BBC services.
