Is this available in the UK?

What I am after is just the stick on bit which I will hook up to a Skoda aerial amp.

Thought this might be a better alternative than 'painting' lines on the rear side window (estate) glass to make an aerial out of...

I like the idea of this, got a part number for the aerial amp Karl?

The Touran one I had my eye on was 1T0 035 577 P.

Went back to look closer today and the scrap yard was closed!

As far as I remember, the aerial from the stereo plugged straight into the amp with a FAKRA (white) connecter, the am was screwed to the roof under the headlining behind the C-pillar and the amp was soldered to the window aerial which appeared to consist of a very short orange line trying hard to impersonate a rear window demister!

It really did seem that simple. To the point where I'd consider 'drawing' an aerial on my Octavia glass using demister repair paint and connecting the amp to that.

Alternatively, this might suit you as I think you wanted DAB!

The official Skoda Octavia '07 part is in another thread on here. I'm still trying to work that one out as I can't see how it accounts for the current through the demister (when it is in use).
