below the radiation plane of any INMARSAT or radar
antennas, and away from any other high-power
transmitting antennas (see Figure 8 on page 19).
high enough to provide an unblocked view of the sky in all
directions, and that minimizes or eliminates any objects
that block the 2201’s view of the sky (the 2201 uses
satellites down to zero degrees elevation or to the horizon).
away from masts or objects that could “shadow” the 2201,
but where there’s an adequate view of the sky.
To avoid mutual interference among different antennas on the
vessel, see the recommendations in Figure 8 below. This figure
shows the minimum distances that should separate GPS/WAAS
antennas from other antennas and physical mounting surfaces.
Normally, these guidelines produce a relatively trouble-free
installation. However, you may want to adjust these distances
to the particular equipment, since every installation is unique.

Mounting the 2201 You can mount the 2201 in one of two ways:
onto a standard antenna mast
onto a flat surface
