I believe Rich Fry pointed this out a couple months ago. The effect can be
seen when using the surface wave modeling tool in 4Nec2. At first, it
surprised me since nearly all base-fed, vertical radiator elevation profile
charts show little field strength at low elevations (1 or 2 degrees), even
when fed over a substantial radial field. Typical vertical profile charts
show high surface wave field strength only over salt water. The same is
shown using NEC modeling programs unless a surface wave tool is used.
