Yagi antennas
Factor Explanation
Frequency Often used in 330-960 MHz bands
Gain Varies with size (typically 11 dBi to 16
dBi)
Stackable gain increase 2 Yagi antennas (+ 2.8 dB)
4 Yagi antennas (+ 5.6 dB)
Wind loading Less than a parabolic grid antenna
Tower aperture required Unstacked: Less than a parabolic grid
antenna
Stacked: about the same as a
parabolic grid antenna
Size Range from 0.6 m to 3 m in length
Front to back ratio Low
Cost Low
It is possible to increase the gain of a Yagi antenna installation by placing two or more of them in a
stack. The relative position of the antennas is critical.
