Antennas do not amplify signals in the sense of increasing their power; instead, they collect and convert electromagnetic waves from the air into electrical signals. The term "amplification" in the context of antennas refers to their ability to focus and thus effectively increase the strength of a received signal from a specific direction, making it easier to detect and process. This is particularly important for small signals, which might otherwise be too weak to be detected against the background noise.
