Can you use a loft digital TV aerial for a DAB feed?

    Hope this is in the right forum, please forgive the noob if it isn't!!:)

    I have a loft aerial for digital tv that I no longer use since I've got Sky.

    I've got a DAB radio with a built in aerial but it gets a pretty limited signal so I've been thinking about getting a rooftop DAB aerial to try to get better recption on a wider range of stations

    Before I do that though I thought it would be worth asking if my digital tv aerial would receive DAB signals as well?

    It might do if it is a wideband aerial and is pointed in the direction of your local DAB transmitter, and you don't use frequency-limiting boosters/amplifiers (e.g. a masthead amplifier that filters for UHF only).

    It worked in my case - taking me from a variable 60%-ish quality with the dangly wire to 100% on all stations.

    Have you tried plugging your existing TV loft aerial into your DAB radio?

    The answer is not very well DAB is VHF band 3 (an old 405 line ITV aerial will work fine as VHF band 111 was used for this) with the active element at around 2 ft long, UHF TV aerials are designed for the much higher frequencies of the UHF band with the active element (half wavelength) of around 6"
