Hi Well I have noticed that my Iphone has a much better single when its in the docking station with or without the USB cable attached at the docking end! So its not the cable or power that is enhancing the signal! A quick Google shows Im not the only one to notice this so what causes this? Is the there an aerial connection in the plug thus extending it? Is it reflecting the signal? What?? And has any one made a small plug in aerial for it?
