Thanks Monzta
Must check mine, I am getting rear condensation also, and I have just replaced the aerial.
In my case, I think the left lights cluster gasket is letting in water, rather than the aerial, as I notice a small trickle making its way into the wheel-well after a wash.
Something to check for you, that might cure your problem simply; the aerial is provided with a rubber drain tube, that diverts water outside through a plastic channel about 2 cm diameter in the bottom of that wheel-arch. There are two of these exit channels there, the second one takes a drain pipe from the sunroof to the outside. You need to check if one or both of these drain pipes is damaged and leaking, or more likely, the outlet is blocked or the pipe not fitted properly to its correct aperture.
You will need to pull back the trim panel on the left of the boot. Disengage it from the rubber boot seal, and pull it back out of your way.
All will be revealed.
