Raymarine forum

I have a used RD218 that I would like to test before installation. It will be connected to a E120.

The RD218 User Manual talks about grounding the array to the boat's RF ground system. To test I will be connecting power from a stand alone 12v marine battery to the E120, through a fused connection. If I want to bench test before installation, what is the best way to ground this? Can it just go to the negative battery terminal, or do I need some separate ground?

Thanks.

YoBub,

Q. If I want to bench test before installation, what is the best way to ground this? Can it just go to the negative battery terminal, or do I need some separate ground?
A. Your suggestion is quite acceptable for testing the radome.
