I've just bought a replacement radio alarm clock with DAB radio. The
radio will pick up an adequate signal in one location but not where it
needs to be.

Is there anything I can do to improve matters? The aerial is a thin wire
permanently fixed into the back of the unit.

Cut the wire aerial short. Connect the coaxial inner of the cable from
an outdoor aerial to it. Leave the coaxial screen unconnected. It will
transfer enough signal to work, despite the inefficiency.
