I don't top post - see either inline or at bottom.

Keep the runs separate.
And a bare minimum of 1' between the "power" lines and the coax.
Induction currents can happen in "dirt".

Using some type of metallic conduit for at least one of the runs will help
too
or even just wrapping them in some tinfoil before you cover them
