I often see the assertion that it is better to not bury radials.

Here's a data point for all. I'm taking down my 102 ft dipole
and putting back up my 130 ft dipole. I measured the resonant
frequency and feedpoint impedance of the 102 ft dipole both
while hanging in the air as a V and laying on the ground.

Hanging in the air: Resonant at 4.52 MHz with a feedpoint
impedance of 22 ohms.

Laying on the ground: Resonant at 2.17 MHz with a feedpoint
impedance of 108 ohms.

Laying the insulated wires on the ground resulted in a
reduction of VF of about 50%. The marked increase in
feedpoint impedance was due to the attenuation of the
reflected waves arriving back at the feedpoint and
agrees closely with my calculations of such.
