I fitted the aerial 2 weeks ago but the reception was that bad I could not even get a half good reception even on radio 1 so I went is search of a soloution and came up with this. Found them in halfords for something like £15 and thought I could get one cheeper from fleebay and there are a few people that are selling them for less than half price.
One thing though, when you connect it up make sure you use the blue lead at the back of your headunit that you use to power a amp with and not the blue/white lead for an electric aerial, as that is what I used and the reception was only marginaly better (even with the standard aerial back on).
I actualy got so pi55ed off with it I went to take it out yesterday and just have the standard aerial back on but thought I'd try connecting the power the other way round and hay presto, perfect signal.
I hope this helps a few people out.
