Default Anyone know where I can find plans for an artificial ground?

# The radial connected with the shield of the coax is the ground.


How does that configuration of a monopole with one radial differ from a
dipole?


The true horizontal dipole (electrically symmetric) radiate in one
direction
only. A monopole in all directions.

So a half wave wire broken at the center is a monopole with a single
radial if it is fed directly with coax?


# Yes. The one leg is the radiator and the second is a ground (like a
# satellite chassis).

So with direct coax connection, one leg radiates and the other leg is
ground?


# Yes.

Would you be willing to touch the end of the "ground"/"radial" wire while
transmitting?


# The electron density changes periodically in the both legs (while
# transmitting).
# Are the voltages equal in the both legs?

But the question was: if the half of the antenna connected to the coax is
ground, would you be willing to touch the end of that half while RF power is
supplied to the center conductor connected half of the antenna?

That would be a good way of verifying your theory.
