Is it possible that the shielded jacks on the Ubiquiti surge protector aren't connected to the grounding point for the device? There is a bit of a physical gap there in the photo. After a lot of years reading expert opinions about grounding (as opposed to bonding), and tackling a few nasty ground loop situations, I'm staunchly in the camp that grounding a conductor to more than one earthing point adds no benefit and can cause a lot of problems. If Ubiquiti is actually doing this, I'll stand up and say that they're wrong. There are enough experts with different opinions that either method can be backed up by an expert.
