The options for car radio antennas include internal car antennas, external car antennas, power antennas, and satellite antennas. The internal antenna is the least effective and most cars come with either the external fixed antenna or the power antenna unless their is a satellite radio in the car and then it is a satellite antenna.

It sends out signals through the air to a radio tower.
