When inspecting your antenna connections, you may find that your antenna mounting hardware or mast is corroded, rusted, or broken in some other way. In that case, replacing the antenna will usually do the trick. Since rust and corrosion can prevent the antenna from making a solid connection with your head unit, simply replacing the unit will often result in better reception.

There are also a handful of other cases that call for a new antenna. For instance, some cars come with “grid style” antennas mounted on the rear window glass instead of conventional whip or mast antennas. These flat antennas have some aesthetic benefits, and they can’t be broken off by a car wash or a vandal, but they often suffer from poor reception in big cities or hilly areas. In some cases, a whip antenna will provide better reception.
