shark fin aerials

[stoph]

Has any body fitted a shark fin aerial to their car, was it easy and are they just as good as the normal ones? mine doesnt work and instead of replacing it with a standard i thought i might go for a bit of snaz. I've got a mark 4 1.8t if that helps 

cheers

I had one on my mk3 as got fed up with removing the beesting everynight, worked ok, I will try and get you a pic.
