It clamps differential via ground so at double the voltage.
But they run clean with GDT and not solid state.

Strange, I have both 450i and 450m running gigabit with no errors. Using
“Cambium sync” though.
So basically you’re saying the GDT version is better for data integrity? And
only for Cambium radios?
What about surge protection, it looks like it clamps all 8 wires at 90V to
ground, but doesn’t try to clamp the differential voltage at some lower voltage
like the other version? I’m not sure how much of a problem that might be.

It doesn’t mess up Cambium. Cambium can have frame check and crc errors with
nothing more than plain cable. Adding solid state surge suppressors causes
problems for some reasons. 100% gas discharge tube cures that.

Sean, what do you find is the advantage of the CAT6-APC over the GIGE-APC-HV?

Hi Eric,
yes the new Cat6 gas tube version is what we use for 450i and 450m

What surge arrestors are you using with the 450m 5ghz? Is that the new CAT6

Here's the equipment box we just rebuilt for one of our larger tower sites.
A special shout out and big thanks to both McCowen Tech for the ground cards
and Packetflux for the amazingly awesome Rack Injectors!!!
the other equipment is:
Planet GS-5220-48T4X switch
Mikrotik CCR
600Watt power supply for Rack Injector (will be adding a second to load
balance)
Dataprobe iBoot PDU
fan tray
this site has these radios:
2 x 5GHz 450m
9 x 5GHz 450i
3 x 5GHz 450
1 x 3GHz 450m
3 x 3GHz 450 (1 is being replaced by the 450m)
Siklu EH-8010FX (10Gbps backhaul)
SAF Integra-W 18GHz (650Mbps backhaul - backup)
