3.6.2 Yagi Antenna Description
A Yagi-Uda Antenna, commonly known simply as a Yagi antenna or Yagi, is a directional
antenna system consisting of an array of a dipole and additional closely coupled parasitic
elements (usually a reflector and one or more directors). The dipole in the array is driven,
and another element, typically 5% longer, effectively operates as a reflector. Other
parasitic elements shorter than the dipole may be added in front of the dipole and are
referred to as directors. This arrangement increases antenna directionality and gain in the
preferred direction over a single dipole.
Since Yagi Antennas are directional, they must point directly at the other antenna
through a clear line of sight.
