Radio antenna does not work unless not grounded

When the antenna wire is hooked up properly the signal is no better than when nothing is hooked up. However, if I tape over the antenna wire's ground with electrical tape, so only the center rod makes contact with the radio, it gets good reception. Why???

The car is an 05 Civic with an internal window antenna.

I have an 05 Mustang and have no issue. Not sure what's up.
