I used the VK5DJ Yagi Calculator to design a 518 MHz Yagi antenna with 8 directors. This article provided the practical help I needed to actually construct it. The antenna works great for the 518 and 494 MHz stations!

The UHF Yagi antenna series is available in 2, 3, 7 element and our 70 MHz wideband configurations. All of our antennas can be completely customized to your particular applications. Our antennas can be black anodized, fully welded, vertically or horizontally polarized, and heavy-duty versions are available.

In this tutorial i show you how to build a Yagi antenna for the 70 cm band (430-440 MHz). This antenna can be used to receive the ham satellite communications with any portable UHF receiver. Here i provide all build steps, with all dimensions you need.

Westell’s UHF Yagi Antennas are made for UHF Public Safety applications. Vertical or Horizontal polarization as well as 8 element construction provides excellent performance and durability. Perfect for directional, point-to-point, or point-to-multipoint applications.

The YB Series are high gain yagi antennas which will provide excellent point to point communication in RF control, short or long haul link and other applications calling for highly directional antennas. YB Series antennas exhibit narrow beamwidths and high front to back ratios to help minimize potential interference to and from other systems.

Building UHF Yagis — A Practical Approach W6PQL treats us to a detailed photo essay on how he builds his well-designed UHF Yagi antennas. he method of construction de- scribed here can be used on most UHF Yagis, and is especially useful for the 70, 33 and 23 cm bands. I make all my antennas with hand tools, hardware store aluminum and a simple
