It receives signals – primarily radio and sometimes for things like GPS, OnStar, or even your car's security system. It also, though less commonly these days, can transmit signals – things like keyless entry or tire pressure monitoring data. Basically it’s how the car “hears” and sometimes “speaks” to the outside world. Think of it as your car's ears and sometimes its voice. It’s connected to the radio receiver, the navigation system, and other electronic components. It takes those radio waves floating around and turns them into something your car can understand – music, directions, emergency alerts, whatever. The antenna itself is usually a simple metal rod or wire, but it’s tuned to receive specific frequencies. Honestly, you’ll notice if it goes bad. Your radio reception will get really weak, maybe just static. If it's tied into other systems like GPS or OnStar, those features might stop working, or work intermittently. A broken antenna doesn’t usually stop the car from running, but it definitely makes the driving experience less enjoyable. It acts like a shield against interference, and when that shield fails, everything gets fuzzy. We carry a good selection of these at Fixparts Online, and getting a replacement is usually a pretty straightforward fix. Long-term solution: Antenna (MPN 420035849) is backed by a 12-month warranty!
