Here is how to build a useful NEC-2 model of a ground mounted 160 meter
vertical.

Place a vertical with four radials 1' over real GND. Use 20 current segments
for each of the five wires. Place the RF source in segment 2. Place an RF
load representing the counterpoise loss resistance in segment 2. Make this 5
to 15 ohms depending on your radial system. For example, for sixty 1/8
wavelength radials use 5 ohms.
