A repeater is a type of device that can repeat, or send out again, a signal or message. It is often used in areas where the original signal may weaken or become distorted, such as in radio or television broadcasting, or in wireless communication networks. For example, a radio repeater could be placed on top of a mountain to help increase the signal strength and reach of a radio station in a specific area. In addition, a repeater can also refer to a person who repeats something that has already been said or done, such as a student who needs to repeat a grade or a athlete who has won a championship multiple times.
