For instance, a loose or corroded antenna can cause poor reception or no reception at all. In that case, tightening the antenna connections or buying a new antenna will fix your car radio problem.
If you've recently moved to a new area, or you're just trying to listen to one station that you can't receive anymore, then an antenna booster may also fix the problem. This isn't going to be the fix you're looking for if the radio doesn't work at all, but if you're just having a problem with weak signals, then it may do the trick.
Another surprisingly common car antenna issue has to do with manually retractable whips. If your car has one of these, and you haven’t already checked it, then you’ll want to verify that nobody retracted it when you weren’t looking. If a car wash attendant pushed it in to be helpful, or a prankster shoved it in while your car was parked somewhere, you could very easily climb back in, turn on the radio, and find that it won’t work at all. Some cars are able to receive some stations, depending on proximity and signal strength, with the whip retracted, while others can’t tune in anything at all.
