GARMIN External GNSS Antenna
External Antenna Mounting Considerations
You can install the external antennas on your vehicle to get the most accurate position data for your navigation device. For best performance, consider these guidelines when selecting the antenna mounting location.
- To ensure the best reception, you should mount the antennas in a location that has a clear, unobstructed view of the sky in all directions.
- You should not mount the antennas near the engine or other sources of electromagnetic interference (EMI).
- You must mount the antennas at least 5 cm (2 in.) apart from each other.
Installing the External GNSS Antenna
Always wear safety goggles, ear protection, and a dust mask when drilling, cutting, or sanding.
When drilling or cutting, always check what is on the opposite side of the surface to avoid damaging the vehicle.
This antenna can be installed to provide a stronger GPS signal for your navigation device. This antenna uses a BNC connector to connect to the dock.
