I ran a 4Nec2 (with NEC/4.2 engine) surface wave plot for a 160m 1/4-wave
vertical radiator over a
field of 60 radials with average ground conductivity. Input power = 1.5KW.
4Nec2 was first set to analyze field
strength at 10 km or 60 wavelengths on 160m. That's way out there...

Next, I ran a simulation of the far field plot for the same radiator:

The far filed shows zero field strength at zero elevation. By contrast, the
surface wave analysis shows that the field strength never drops below 12.2
mV/m at any elevation, including zero elevation.
I'm just the messenger....
