This is a GPS++FM car antenna, which looks like an elliptical arc shape and is very harmonious when installed on the roof. In addition, the antenna design adopts the parallel input power carrier solution, which greatly improves the signal reception and transmission; a signal light is added to the power supply processing to facilitate the judgment of whether the antenna is working properly. The blue light indicates that the antenna is working normally.
