The Yagi-Uda beam antenna was invented 100 years ago, in 1926, and Contest University (CTU) is celebrating its centennial with a live Zoom webinar this Saturday, September 19, 2026, at 1600 UTC (noon Eastern). The free webinar, titled “The Yagi Turns 100,” will be presented by Greg Ordy, W8WWV, and will be available online at w3lif.org/yagi. Ordy will walk through the history of this amazing antenna that has been a mainstay of amateur radio DXing and contesting for a century. There is no pre-registration for this event. Click on the link (above) before 1600 Zulu on Saturday to watch. Contest University Chairman Tim Duffy, K3LR, and Scott Jones, N3RA, will be monitoring the chat during the presentation and will relay questions from viewers to Ordy at the conclusion of his talk.

Duffy says the webinar will be recorded, and the recorded link will be posted on the CTU website next week.
