Power Antennas
Radios were a big change for the modern automotive era, and most drivers grew up with some type of radio in their cars. Automotive antennas were a way that automakers were playing around with eliminating the antenna from the design of the car completely. Automatic antennas stayed around well into the early 2000s and shaped the way that car design is today. You’ll notice that most modern cars don’t even have an antenna because the feature went extinct due to the rise of streaming (via Radio Car Stuff).
Power antennas were expensive to replace at the time and that’s why automakers started to do away with them. The current antennas are just built right into the frame of the car. Still, power antennas were a feature that shaped the automotive industry as well know it.
