AM radio antennas are typically large, vertical towers that are made of metal. The towers are grounded at the bottom, and the top of the tower is connected to a transmitter. The transmitter sends out radio waves, which are electromagnetic waves that travel through the air. When the radio waves reach the antenna, they are converted into electrical signals. These signals are then amplified and sent to a radio receiver, which converts them back into sound waves.
The size of an AM radio antenna is determined by the frequency of the radio waves that it is designed to receive. Lower frequency radio waves require longer antennas, while higher frequency radio waves can be received by shorter antennas.
FM radio antennas
FM radio antennas are typically smaller than AM radio antennas, and they are usually mounted on the roof of a building or on a pole. FM radio antennas are made of metal, and they are also grounded at the bottom. The top of the antenna is connected to a receiver, which picks up the radio waves and converts them into electrical signals. These signals are then amplified and sent to a radio receiver, which converts them back into sound waves.

How AM and FM radio antennas work together
AM and FM radio antennas work together to provide a wide range of radio programming. AM radio antennas are used to receive low frequency radio waves, which are used for talk radio, news, and sports. FM radio antennas are used to receive high frequency radio waves, which are used for music, sports, and weather.
By combining the signals from AM and FM radio antennas, listeners can access a wide variety of radio programming, regardless of their location.
