I'm not sure what there is in there. Heard vague recollection of a pair
of CAT5s in there, but not with any certainty. This is why we need to
go survey the place. I would expect their grounds to be tied given the
power system changes, and the conduit to be bonded. Worst case though we
can omit the shield as CAT5 Ethernet is only magnetically coupled (has
isolation transformers) and uses differential signaling.
I'm kind of hesitant to introduce fiber to HamWAN where it's not
absolutely necessary. We have enough problems with proper RJ45
terminations, never mind asking people to re-terminate fiber if
