RF ground

[Kwik]

Just finished installing my Raymarine Axiom 9 with the Sirius SW200 and 3D sonar on my 2004 240 Sundancer......almost. I have no idea where to land the RF ground on the two units. What is the RF ground. Where to land to it? TYIA

We use a sintered grounding plate for super-duper RF ground. Most people get away with grounding to the ship’s common ground bus.
