If you have a multimeter/DMM, check for "0 Ohms" resistance from the radio's metal chassis to a known-good vehicle ground with the antenna DISCONNECTED, but with the Radio's primary power harness connected...
If you show anything higher than 1 Ohm, you need to check the radio's black ground connection, and confirm it's terminated to a solid vehicle ground point...
It could be a multitude of other issues, but since the antenna is involved, a ground issue seems probable...
