Seatex Seapath 200 Installation Manual, rev. 13 Installation

The installation procedure described below assumes that the Antenna Bracket delivered by
Seatex is used and that a holder for this Antenna Bracket is prepared in accordance with the
antenna holder drawing in chapter 4.
3.4.1.1 Installation procedure
The mechanical installation of the various parts is performed in the following steps:
1.
First the user has to make a holder for the Antenna Bracket (the holder is not part of the
Seapath delivery) and have it properly fastened to the mast in the preferred orientation
(horizontal or vertical). When the Antenna Bracket is mounted vertically, the drawings in
Figure 2, Figure 3 and Figure 4 are not correct.
Figure 1 Dimensional drawing for the antenna holder
2.
Bring the Antenna Bracket, the two GPS antennas and the antenna cables as close as
possible to the location of the antenna holder. While both the GPS antennas and the
Antenna Bracket are down on deck, mount the GPS antennas on the Bracket with both
antennas oriented in the same direction. Depending on antenna type, labelling on the
antenna housing (arrow or text) or connector location is used to determine direction.
Figure 2 shows the antennas oriented with connectors pointing in the same direction. The
antennas are not marked, and are interchangeable but called no. 1 or 2 for reference. The
normal orientation of the Antenna Bracket is along ship with antenna no. 1 aft. It can,
however, be mounted in any orientation, provided it is approximately horizontal.
Note
Both GPS antennas have to be mounted on the Bracket oriented in the same
direction, otherwise the system will have degraded heading performance.

The screws for mounting the GPS antennas to the Bracket must be secured with washers.
