Can the antenna attached to the car roof enhance the signal of car navigation

The antenna attached to the car roof can not enhance the signal of car navigation.

The antenna on the roof is also called vehicle antenna, which is mainly used to receive external signals. In addition, the function of the antenna on the police car is to receive mobile radio, especially the special band information of the police.

In addition to receiving signals, the car antenna is also an electrostatic releaser, which mainly releases the static electricity accumulated in the car shell to protect the safety of passengers and body circuits. On some high-end vehicles, the antenna has the aerodynamic effect of air turbulence. Some can even be used as the antenna of the car phone, which can enhance the signal strength very well.
