Simple Ham Radio Antennas--Three-Element Yagi Antenna Dimensions. Post #664.

If you're unable to view this video, please insert this address into your browser search box: This video by Stan Gibilisco (W1GV) provides an excellent tutorial on the design parameters of a three-element parasitic array HF antenna, known as a Yagi Antenna.  Stan provides all of the necessary formulas for the reflector, director, and driven elements of this antenna. If you're considering upgrading the performance of your amateur radio station, a simple yagi antenna may be a cost-efficient and effective way to add more "punch" to your signal.  You can either homebrew your yagi or opt for a commercially available yagi.  Of course, you'll probably need a modest tower and a rotator to direct your signal to the desired areas.  This would entail a consideable expense, especially if you want a yagi for the lower HF bands (80 to 20 meters).  However, a three-element yagi for 10 meters would be within most budgets and would require a less expensive tower and rotator.  A yagi antenna and a tower aren't necessary to enjoy amateur radio, but a yagi could optimize your signal, especially if you participate in contests or DXpeditions.  A necessary starting point for your "dream" yagi is this video tutorial by Stan.  Good luck!
