Grounding and Lightning Protection
If the Ethernet cable is connected to a device properly connected to the ground, no further grounding of the G-1090 air traffic receiver is needed. Otherwise, there is a grounding hole screw on the bottom of the receiver. Connect the grounding screw to a metallic item properly grounded.
In case of a permanent installation, appropriate lightning protection should be installed between the cable and the PoE, and between the antennas and the G-1090 Air traffic receiver.
The G-1090 receiver is protected from lightning strikes occurring at the level of the Ethernet cable. In fact, it has its own lightning protection equipment inside the receiver. This protects specifically in the case lightning creates a parasite current in the Ethernet cable between the receiver and your internet source. Note that the lightning doesn't need to specifically hit the Ethernet cable to create such a current, an inducted current could be created also if the lightning happens in the area of the cable.
To protect your internet source from lightning strikes, INVOLI provides lightning protection. The installation should be according to the scheme below. Both the G-1090 receiver and the lightning protection device should be properly grounded to ensure effective protection. This is represented in the picture by green grounding arrows.
