Groove/Metal 52AC case grounded?

Hi,

We are on a sailboat with a floating ground, meaning that our bonding circuit, which connects virtually all metal parts on the boat, should not be connected to either DC+ or DC-.

I have tried to run another outdoor CPE/AP (Alfa Tube 2H) and it appears the N-connector and hence the case is connected to the POE positive. The antenna is mounted on a stainless L bracket which creates a conductive path straight to the mounting mast. This could lead to current flowing through our bonding system and consequently devastating stray current corrosion. This will not work.

Does anyone know if the Mikrotik Groove or Metal 52AC is case grounded? In other words, is either POE+ or POE- connected to the N-connector or the case?

Thanks!

The Groove has a plastic case so it is not grounded. The the outside of the N-connector on the Groove, Metal 52ac, Bullet etc. is connected to DC- by the circuit board . You will have to fabricate an insulating mounting pad to attach your bracket to. You could also strap the Groove directly to any verical pole and let the Groove support the antenna .
