Mechanical protection is what's good about underground.
There's not a lot of practical difference from an RFI standpoint (either
can be good or bad..)
I always assumed that common mode currents should be at least slightly
attenuated by the surrounding earth, but maybe not...
Probably, but also probably not as well as a single 2.4" 31 mix toroid
would do..
Depending on dirt to do your RF choking is a pretty sketchy maneuver.
I suppose buried wires are less likely to be hit by lightning, but I
kind of consider that a "mechanical" factor, more than an EMI/EMC factor.
