Confirm vessel electrical capacity, compatible Garmin electronics, grounding, and installation requirements before commissioning this 4 kW radar system.
What array size is included?
The package includes a six-foot open-array antenna and pedestal. This larger antenna requires structural support, clear rotation space, protected cable routing, and appropriate service access. Confirm cable length, mounting dimensions, display compatibility, and power requirements before installing the six-foot Garmin array.
What does xHD3 technology indicate?
