Radio signal was intermittent so went to unscrew antenna from housing on front roof and it broke off into the housing. I am having trouble sourcing a new housing an antenna and the dealership is wanting an ridiculous amount to replace it. I also noticed that there is a shark fin antenna on the back end of the roof. My mother bought the car used so not sure if the shark antenna is a replacement for the rusted out one on the front. Does anyone have any experience with the antenna and/or replacing it that could give some advice?

 

SHARK FIN. under no circumstances are you to disturb that fin. That fin sends a signal to your ecm that disables the antitheft on your hhr. If you do disturb it, you can expect ignition and starter problems.
