When replacing the factory car radio with an aftermarket one, it's possible to experience diminished antenna reception compared to the original radio. To address this issue, antenna amplifiers are available on the market. This particular antenna amplifier is easy to install and significantly enhances antenna reception, improving it by at least twice the strength. In fact, in most instances, the antenna reception surpasses what you're accustomed to. If your vehicle lacks a visible roof antenna, it is highly recommended to procure this component.
