Use thick eithernet wire as its coax and uses ground and everything uses
an isolated interface to it. AUI is imune to ground loops and can be
burried.
The other approach is RS422/485 type interconnect as it is differntial.
Myself I'd sink several peices of weather proof coax and build on that
using AUI (thick eithenet).
If you have a choice go underground as air trips invice lightining.
