Copper radials could be better.

Ed Laport who worked with Brown, Lewis, and Epstein at RCA wrote on page
121 of "Radio Antenna Engineering":

"The radial disposition of wires in a buried or surface ground system is
dictated by the natural paths for returning ground currents. Meshes opf
crossed wires which were once widely used, should not be used with
vertical radiators because the return paths are not direct and
eddy-current losses in the closed loop circuits of the mesh can be
appreciable."

With a fine enough ground spacing, though, I would think that the path is
'direct enough?'

I thought the entire point of the ground plane was that the induced currents
are necessary to make up for the current sources that are 'supposed' to have
come from the 'missing' half of the antenna?

The currents need to be induced in low-loss material for efficiency.

The performance is as if a vertical and its reflection made up a dipole
in place of a monopole and its reflection. The equivalence is very good
in most respects.

According to Laport, G.H. Brown, the inventor of the "ground plane
antenna" and one of the famous "Brown, Lewis, and Epstein Trio" at RCA
is responsible for using electrostatic principles for describing a
ground or image plane and writing the equations to quantify the
potentials due to the charges on a system of cylindrical conductors to
be used as in a transmission line to determine characteristic impedance
in terms of capacitance per unit length and the velocity of propagation
of a TEM wave. See page 513 of "Radio Antenna Engineering" for details.

A vertical radiator driven against the earth or a ground plane needs to
complete its electrical circuit between the radiator and ground through
existing capacitance via capacitive (displacement) current. To minimize
loss, ground current in the lossy earth is minimized by using enough
radials of sufficient length to capture nearly all displacement current
before it can flow through any significant length of earth.

If the vertical radiator is high above the earth and far away from
ground, only a few radials suffice to capture nearly all displacement
current. Earth far below is out of the current loop.

When the radials are near the surface of the earth, many radials are
needed to hide the earth`s surface from displacement current with the
vertical radiator. Fortunately, when the radials are closely spaced, any
current induced in the earth doesn`t usually travel any significant
distance before being collected by a nearby radial and this keeps the
earth-current loss down. For the FCC, 120 radials of 1/4-wavelength
evenly distributed around a 1/4-wave vertical radiator are just about
perfect for the medium wave broadcast band.

Some of B, L.& E.`s performance charts are on page 119 of "Radio Antenna
Engineering".

Hi Richard

Thanks for the advice!

However, I do use copper radials from each vertical.
From my Butternut HF9Vw/160 I used 3,500 feet of copper wire to make
the radial bed. These were tied to an 8 foot grounding stake and
connected to the antenna's grounded mast.

I have antennas that did not work well at all when placed in the front
or side yard, but worked quite well in the back yard over all of that
mesh of buried wire!

Because of this, I'm planning on trying to duplicate as closely as
possible, what I had that worked so well for the last 20 years.
