Broadcast towers are tall structures designed to transmit radio, television, and other signals over long distances. They work by sending out electromagnetic waves that carry audio and visual information to receivers, such as radios and televisions. The height of these towers allows the signals to travel further and reach a larger audience. These towers can be found in various locations, often on hills or tall buildings, to maximize their coverage area. Some common types of broadcast towers include AM radio towers, FM radio towers, and television transmission towers. Each type is designed to operate at specific frequencies to ensure clear signal transmission.
