I go out today with a 48v PoE injector and 6 Radio Shack ferrite clamps.
Swapping to 48v made no difference.
Adding a clamp just upstream of the PoE injector made no difference.
Adding a clamp just outside of the RooTenna made no difference.
Seeing no change, I put it back to the 18v PoE and

Mike,
Is there 120v power running parallel to the cable? What else is on this
tower? Any high wattage RF transmitters? I have seen shielded cat5
interfered with to the point where we had to use fiber as the transport up
the tower instead of cat5. Is the enclosure plastic or metal? Have you

Mike, the ferrite snap-on is an inductance that prevents common mode RF,
of
any frequency you care about, from waltzing down the wire into your
system.
You just snap the hinged double-half-core onto the cable over the
insulation
so
Can you define Ethernet problem a little more.
No link lights, intermittent link, no data, small packet data only,

My first thought is bad connector or bad port on a device. I have seen
hub ports that will look fine, do small packets fine, but don't try to
