So a more accurate name for the design may be the Yagi-Uda antenna, but the universal name is Yagi. Yagi antennas are directional, meaning they must be pointed directly at a signal source for peak performance.

Because they’re directional Yagis are not suitable as mobile antennas, so they’re used at fixed locations. They provide better signal range than do omnidirectional antennas, which receive signals from any direction and transmit in a 360-degree pattern.

Popular uses for Yagi antennas included OTA television, amateur and CB radio and, of course, cell phone reception.

For an excellent explanation of how a Yagi antenna works, I encourage you to watch the video above featuring Don, the Antenna Engineer, from weBoost.

In the video Don uses a Yagi for his directional antenna example, and explains how it works. We’ve started this video at about the 3:00 minute mark where Don begins discussing the Yagi.

If you’re interested in how omnidirectional antennas work, we certainly encourage you to view the video from the beginning.
