A car antenna booster is used to 'boost' the radio waves of the car's antenna. This is usually used to improve radio quality and reduce static that might be heard.
An antenna picks up waves by converting electromagnetic fields into electrical signals. When radio waves interact with the antenna, they induce an alternating current within the antenna which is then processed by the connected circuitry to extract information or energy from the waves. The size and shape of the antenna determine which frequencies it is most sensitive to.
A dish antenna must face the arriving waves.

Yes. A good rule of thumb is that if the device has an antenna, it uses radio waves. An antenna would not be needed if it didn't use radio waves.
An antenna works by converting electrical signals into radio waves for transmission and vice versa for reception. When an electrical current flows through the antenna, it creates electromagnetic waves that can travel through the air. These waves carry information in the form of radio signals. The antenna's design and length determine the frequency of the radio waves it can send and receive.
For wireless communication systems, the antenna is one of the most critical components. A good design of the antenna can relax system requirements and improve overall system performance. An antenna is the system component that is designed to radiate or receive electromagnetic waves. In other words, the antenna is the electromagnetic transducer which is used to convert, in the transmitting mode, guided waves within a transmission line to radiated free-space waves or to convert, in the receiving mode, free-space waves to guided waves.

They are picked up by the antenna.
He generated electromagnetic waves by accelerating charges back and forth rapidly in an antenna. He detected the waves by using a similar antenna that would convert the electromagnetic waves into electrical signals.
