Choosing the best mounting location

Before you drill or cut, choose a mounting location that meets the following criteria. The 2301

should be mounted:

• where there's enough mounting clearance to easily connect the cable.

• low on the vessel, since side-to-side motion caused by the vessel's rolling can

degrade speed-over-ground (SOG) and course-over-ground (COG) readings.

• below the radiation plane of any INMARSAT or radar antennas, and away from any

other high-power transmitting antennas (see Figure 7 on page 14).

• high enough to provide an unblocked view of the sky in all directions, and that

minimizes or eliminates any objects that block the 2301's view of the sky (the 2301

can use satellites nearly as low as the horizon).
