Have you tried the WB GigE-POE-APC?

I am going to try a tycon power DC POE tomorrow, see if that will work, just
need to get it working at this point... Next step would be to run a new Cat5.
Current Cat5 is Apex9.

Another (totally hypothetical) thought would be perhaps one of the pairs has
a slight DC unbalance causing the DC current not to split equally, thus causing
some DC flux in one of the transformers and degrading the pulse characteristics
of the transformer. Which could happen if the UBNT injector has transformers
with higher saturation specs than the Packetflux injector.

Is it an AF24 or 5? The 24 uses 50 watts. The power control relays on the
regular and GigE injectors will only handle 1A @ 48VDC. If it's a 24, you're
likely over that. The relay contacts are probably fused.
The AF specific single-port injector uses a solid-state relay like a
SyncInjector and can handle 2A, or more, I forget what Forrest said.
That said, if the radio isn't getting enough power, it will be unpredictable.
I have seen this happen. Sounds like you've tried the PacketFlux single AF
injector and that does it too? Works fine with the UBNT brick? I have no idea.

Guys this is not my first rodeo, This is the new Gigabit 8 Port Injector
and I have also tried the Packetflux Airfiber Injector, same issue, switch to
stock UBNT POE and it works fine. This is an all DC site, with separate DC to
DC converters and everything is fused.....
See POE directions direct from Packetflux

It should not work with a regular POE injector. 50 watts is too much
current for 4 pins; you need to supply power on all 8 pins. And that, in turn,
requires transformers to isolate the data lines.
So I would not expect it to work at all with a vanilla POE. Well, maybe
it might work for a little while, and it would probably only do 100baseT. Then
the 4/5 & 7/8 pins will fry.

Anyone else seen any issues with the Airfiber Module or running the
Airfiber through the Gigabit POE Injector. I am seeing an issue with TX data,
RX works fine, getting full bandwidth. TX I get about 2Mbps. Hooked up to
Regular POE and everything is fine, any ideas?
