This is a wire that is connected to the radio system of a car used to convert electrical energy to radio waves.

An antenna is as important as to any other part of an auto. This part should be replaced when it starts becoming loose from the top of the car and does not function as required. Another reason to replace this device is attributed to the fraying of the wires connecting the antenna. A poorly installed antenna means that it has poor reception. In this aspect, this can be replaced with a new one that has a better reception than the former.
