I upgraded my radio and my antenna cable was bad. So I went to the junk yard and got a used one to fix it. But it Didn't work so I bought a new one and it still don't work. What in the hell!!!!!!!!!!!!!!! It's just a cable.
I need help any one?

 

try a simple Wire about 3 feet long, direct on the Radio Antenna connector
when it still doesn't work, then the Tuner part of the radio is unserviceable.

when its work.
then theAntenna cable is defect (kinked)
or your antenna has a short to ground
