Elevated radials (two or more) can provide an artificial ground plane for an elevated, 3-meter vertical radiator installed just above the junction of those radials. The elevated radials won’t radiate if they are of equal lengths, and installed in the horizontal plane. This configuration does not need a conducting path to a good earth ground for most efficient radiation, and will radiate the same fields no matter how high it is above the earth. This antenna design was invented by George Brown back in the 1930s — the “ground plane” antenna.
The caveat here is that the elevated radials must be horizontal. If they slant down toward the ground as part of the means of guying the 3-m radiator support, they will radiate, and the effective radiating length of the antenna will exceed the length of the 3-meter whip.
