Get a step-on lawn edger, which is a blade attached to a handle, and you step
on it to make a slit in the dirt.

Step, wobble it a little to open it up, and make a nice slit, and work the
coax down into it, alternating slit and pushing down.

Just stomp around to close the slit again.

Easiest after a rain.

I bury just plain ordinary coax and it works fine, by the way.

(You can find the coax again with a portable AM radio. Put radio on the
ground tuned to a weakish station, and aim the radio to null out the
station. Drag the radio across the area the coax is in in that orientation,
and the station will pop up as you cross the coax.)

I paid a guy $300 to find wires for the sprinkers in the front yard and
then buried a plastic 24oz cup upside down right next to them, Funny now
the dirt is covered them but I have some idea what area they are in.

Metal dectecting one time I found a year old quarter about 2' down in
the dirt in a park that was built 20+ years ago, gotta wonder how that
got there.

I think the cable will become one with the earth................
