Has anyone tried modeling arrays of vertical antennas with a very simple
NEC model, inserting a resistive load of a few ohms in the bottom segment
to represent the non-ideal grounding? Off hand, the patterns should be
*about* right (the physical radiator is the right length), it's mostly a
matter of whether the impedances (and mutual impedances) come out properly.
