What is the problem when the car radio signal is poor?

[SiennaFitz]

The reasons for poor signal are as follows: 1. Signal interference or obstruction: Since the radio mainly receives broadcast signals through the antenna, the quality of signal reception is affected by various factors, such as mountainous areas, tunnels, high-rise buildings, magnetic fields, or areas with poor signals, which can obstruct or interfere with the signal, making it difficult or impossible for the radio to receive signals. 2. Interference: When some devices that have not passed relevant electromagnetic compatibility tests are installed in the vehicle (such as certain dash cams, car phone chargers, etc.), the circuits inside these devices can radiate strong interference signals, affecting the radio's normal reception of stations. 3. In bad weather conditions: The radio signal is worse than in normal environments. For example, in bad weather conditions such as cloudy days, rainy days, foggy days, or snowy days, the car radio signal will be poor.
