Repeater

Okay kiddo, let me explain what a repeater is! You know when you're talking to your friends on the phone and sometimes it's really hard to hear what they're saying because they're too far away or the connection is bad?
Well, a repeater is like a big microphone that helps with that problem. When you talk into the repeater, it amplifies your voice and sends it out again, so that your words can travel farther and be heard more clearly. It's like using a megaphone to make your voice louder and clearer. Repeaters are often used by people like police officers or radio operators to help them communicate over long distances.
So basically, a repeater helps people talk to each other when they're too far apart or when there's interference in the way. Does that make sense, kiddo?
