That said, mine is working fine but the receiver can't touch the factory one in my Ford.
Or do you think it's HD radio? Not sure what kind of Ford you have but I went from a '13 Legacy 2.5i with HD radio that sounded amazing to an '08 GT and the radio sounds like crap in comparison. Little hints of static here and there, I hate it.
Wasn't sure if my antenna was bad or not like OP but I'm thinking maybe its just the difference between HD radio and non HD radio. Hopefully I'm wrong because I would love to get that crystal clear signal again.
