In today's world, the various components of your Mercedes have been slowly turning into barely recognizable, high-tech versions of themselves. Fortunately, the radio has remained more or less the same, and when you need a little entertainment while driving to work, the Mercedes antenna makes it possible. This device is directly responsible for grabbing the radio broadcasts out of the air. When a station is broadcasting, it sends out a radio wave rich in electromagnetic energy, that your Mercedes antenna is specifically tailored to receive. The basic antenna is made out of metal, for the same reason that metal conducts electricity. The electrons are easily transferred molecule to molecule. As the high energy radio wave hits the Mercedes antenna, it excites the electrons within the part, sending the signal to the radio. The radio is responsible for adding power to the signal, and transforming it back into something humans can understand. When the Mercedes antenna has been broken, or is totally missing, the signal received by the radio will not be strong enough to decode any useful information from it.
