The monthly award, run in association with Campaign, went to Paul Dominet and Brian Connelly of Saatchis for their "Katie Lee" spot.
The judges, Tim Craig and Mark Gilmore of Radioville, voted an ad for Iceland as the runner-up. It was created by Andrew Lloyd-Jones at HHCL/Red Cell.
The winning ad highlighted the perils of credit card fraud and announced the introduction of a new security scheme called "chip and PIN". It features a surly male voiceover describing himself as Katie Lee. "I'm 22, have long, blonde hair and am a PA in an advertising agency." It becomes apparent that the man has stolen Katie Lee's credit card and is using it for himself.
Media was planned and bought by Catherine Becker and Delia Ball at ZenithOptimedia.
The ad was produced by Mark Hanrahan through Shell Like Radio.
Explaining their selection, the judges said: "It was a tough call so we finally fished out the ad that worked the hardest. 'Katie Lee' knows its audience and rams the message home. It's chilling. It's appropriate. It's a winner."
The Aerial Awards are awarded monthly to recognise excellence in radio creative. The winners of the awards are put forward to the annual ceremony, with a judging panel chaired by Nick Worthington of Abbott Mead Vickers BBDO. The annual awards will be held on 4 November. This month's winning ad can be heard on the Aerials website (www. aerials.co.uk).
