It is said that the elevated radials are an artificial ground plane,
simulate a ground plane, form a virtual ground plane, or approximate a
ground plane. It may be that the radials perform the same function as a
ground plane, but do not form a real ground plane.

For example, the Butternut antenna manual at following web address says that
elevated radials are an artificaial ground plane.

What functions do the radials perform that are the same as a real ground
plane? What similarities are there between radials and a real ground plane?

How is the monopole antenna system connected to the
real ground plane - as opposed to an ideal infinite
conducting plane? What about radials buried inside
the real ground plane?

Hi David,

You've recited this more than once. Repetition does nothing to reveal
these as anything more than disconnected statements.

For example, the Butternut antenna manual at following web address says that
elevated radials are an artificaial ground plane.

Simple observation of the wandering usage through that document would
inform most that "ground plane" is a term of convenience.

plane?

There is no such thing as a "real ground plane."

What similarities are there between radials and a real ground plane?

None.
