[TowerTalk] dipole z vs height

[Al Kozakiewicz]

For those who don't want to do any modeling and aren't looking for a high degree of precision w/r/t ground conductivity, I've always found the charts and figures that accompany this article very useful in helping to visualize what happens: http://www.qsl.net/aa3rl/ant2.html

I'm a "visual" type guy, so I modeled Jim's 80m dipole at heights above ground from 10 to 30 meters using three different soil conditions.  Here's the picture-worth-a-thousand-words:

If you'd like to play with variations on this yourself, contact me off-list and I'll send you the ".weq" model file for use with AutoEZ.
