SECTION THREE: Installing and wiring the GPS antenna
• away from masts or objects that could "shadow" the 2301, 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 7 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, since every installation is unique, you may want to adjust these
distances to the particular equipment.

NOTE: Before permanently installing the 2301, try temporarily installing it and
using the 972 to see if the location works well (see "Checking satellite
status" beginning on page 21 to determine whether or not the selected
location provides good reception).
The 2301 uses a mount with an extension, and the cable is routed
through the inside of the extension.
