Yes it would.

Yeah, but grounding it would still be useful for surge suppression, wouldn't
it? If it's not going to hurt anything (as far as breaking the ground loop),
why wouldn't you ground it? seems to me there's some potential for surge issues
with cables running between buildings, so if you have the hardware there, might
as well hook it up.

If you are trying to break the ground loop by just using the injector as an
isolation transformer, grounding is not really adding anything. It certainly
would not hurt to ground it but it is not necessary for this application.

Por que no? Splain it to me on no grounding?

Of course :-).
If your primary goal was to prevent a ground loop, would you ground the
surge suppressor, or just use it to isolate the path?
If the lines were shielded, would you keep one of the shields disconnected
intentionally at the surge suppressor?

Well, of course I prefer a different method:

That cable is not shielded (so the shields would not be connected).
The Gigabit PoE that comes with Cambium ePMP hardware has a full set of
magnetics (all pairs).

I have a customer with bizarre issues. I've replaced almost everything
but odd issues keep coming back.
The customer has a 100' run of Ethernet cable from the house to the
barn, and a switch in the barn. I'm wondering if there might be an issue with
different power sources, possibly different grounds between the router and the
switch. The issues are intermittent enough that I can't ask for them to just
disconnect their barn as it is used for work.
If I install an unpowered gigabit PoE injector in-line with that 100'
run, will that eliminate any issues with different power or different grounds
between different buildings since the buildings would be on separate sides of
the magnetics, or do I need better separation?
