The antenna should be grounded through the internal circuitry of the radio itself.
Not sure about your radio or the antenna plug, but have you tried the antenna from the dock and play home kit?

I have the home antenna for mine on the window sill of a north facing window and have no issues. The adjustability of the antenna may be what you need for your situation.
