Im not convinced, theres a huge difference in quality and it has a delay which shows it's on a different bandwidth

DAB uses a different aerial, but may be multiplexed into the FM, and UHF/SAT frequencies using a suitable 'loft box', or a cable may be run direct to your DAB radio. It isn't available in all areas yet, but is far superior to FM broadcasts.

Maybe when close to a transmitter, but if in the real world, A dedicted UHF, FM and DAB aerial is required. This is when communal living is a bliss - its all done for ya. Its a bit like an old Ford Escord with a coat hanger aerial - Yes it it will pick up the FM broadcasts, But quality �

Ok DAB radio's easy. If you're in a marginal area you can just do a simple loop in the loft. If your transmitter lines up nicely across the signal path you can tack up a very simple arrangement.

Make a loop of copper wire from the palm of your hand around your elbow then do this on the other side so you end up with something which would fit across both arms. �(assuming you're an average sized male & ignore the gaps at the sides where my brackets don't join up Embarrassed

)

Kind of like this

The ends at the top should be connected to the centre and shield of your aerial cable respectively. This will pick up DAB band fairly well.
