Yagi Aerial - English Definition & Meaning

Definition

A Yagi aerial, short for Yagi-Uda aerial, is a specific type of directional antenna widely employed for receiving radio and television signals. It consists of multiple parallel elements, including a driven element, a reflector, and one or more directors, all aligned along a central boom. Unlike an omnidirectional antenna, the Yagi aerial concentrates its reception in a single direction, enhancing the signal strength from that direction. It's like cupping your hands around your ears to hear better, but for radio waves! 👂

Etymology

The term 'Yagi' refers to Hidetsugu Yagi, one of the Japanese inventors of the antenna. 'Aerial' is an older British term for 'antenna,' derived from the notion of something suspended in the air. Together, 'Yagi aerial' denotes an antenna of the Yagi design. 'Antenna' comes from Latin, meaning 'sail yard'.
