Thanks to David Casler (KE0OG) for this excellent, well-paced look at dipole antenna performance. Customary wisdom says HF dipole antennas should be at least 1/2 wavelength above ground for best performance.  Dave use a variety of methods to answer this question. The tutorial is informative and easy to understand.  Here are some additional comments from Dave: How high should a dipole be? What happens if it's too low or too high? We turn to EZNEC antenna modeling software to see that the old rule of thumb of one half wavelength is correct. But there are lots of things going on! Learn about modeling and dipoles in this video.
