Rob, I don't know you, but what I stated is absolutely true.

I've been a broadcast engineer for 40 years, much of the time with a Potomac
Field Intensity meter in one hand and  a notebook in the other working on
documenting AM broadcast antenna system performance and field signal
strength. ( Also measured amateur systems on 160 and 80 meters when I could
borrow the equipment. )

The losses from deeply buried radials is high and goes higher as the
frequency increases.  Yes the soil type and moisture content make a big
difference, but close to the surface or on the surface is optimum.

I know of what I speak.

>One word of caution.
>Don't put the radials too far under the surface. 2, 3, 4, or 5 inches down
is too deep! Remember that you will be cooking the soil ( introducing
losses ) between the radial wires and the surface.
>Try to keep the radial wires an inch or less below the surface.

That is absolutely not true.  There is no difference in performance at
any of those depths.
