I notice that two people have simulated the vertical antenna with radials
using EZNEC, and obtained different results. One simulation shows that the
radials radiate, the other shows that they do not.

Hi Dave,

Your statements above show a serious problem with understanding the
operation of antennas.

The radials are not potted plants merely arranged along the ground (or
in the air) to give a sense of symmetry and balance.

You would go further to engage more in dialogue rather than simply
posting statements. Much of the utility of radials has been
discussed, revisited, and rehashed to no apparent effect against what
you offer above. The last sentence is outrageously wrong for any of a
number of reasons (or proof of some pretty stupid simulation).
