(DG) ACU-300 Ground - why is it important?

Hi JBuss,
Thank you for your enquiry.

The ground connection is provided to meet EMC requirements, more information about this can befound when you click here , normally the ground is connected to the RF ground of the boat - which is something like a dynaplate, ( a sperate plate on the outside of the hull underwater specifically for this purpose - but not all boats have them)

To be honest, if you do not experience RF interference, ( typified by unstable data, erratic performance, vhf 'noise'), then the ground is not required.

regards
