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. See our guide on Satellite Reception for more information.
This could be due to the different frequencies used, or if services are on different satellites. There is also the possibility the signal strength and quality of one multiplex could be different from another. If you have a reception problem with one service in a multiplex you will also have problems with all the other services in that multiplex. Each multiplex also carries the service information which includes the data needed for EPG’s. We can also add in radio services, Red Button data services, subtitles and audio description into a multiplex. This allows broadcasters to use the spectrum allocated to satellite services to the maximum extent, giving you more television services to choose from. Using a multiplex enables us to broadcast a number of television channels at once using just a single frequency. We keep an updated list of the BBC TV services and the satellites/transponders. The satellites are arranged in such a way that a correctly- aligned satellite dish will be able to receive signals from all the satellites in that specific arc. For satellite, the BBC utilises a number of transponders on a number of satellites.
