9.6 Installation of the GPS / DGPS antenna
The antenna must be placed in a position where tall con-
structions, steel wires, masts, etc. do not obstruct the view
to the satellites. Do not, however, mount the antenna in the
top of a mast or tower, as this may degrade the COG and
SOG readings, especially if DGPS is used. Do not place
the antenna close to sources of electrical interference, such
as radar, satcom, etc. If installing the GPS antenna close to
other antennas it must be placed either above or below the
radiation beams. There is full coverage down to 20° below
the horizon.
Beam area
– avoid installing the GPS antenna inside
the beam areas.
Mounting of DGPS antenna MGL-3
Mount the antenna on a standard US 1” 14 thread pipe,
or optional standard antenna mount. Tighten firmly, but
only by hand – no use of tools. Attach the antenna cable
to the TNC socket.
Mounting of GPS antenna RS5640
Loosen the screw (1) of the antenna adapter. Guide the antenna
cable (2) through the adapter and connect it to the antenna.
Screw the US 1” 14 mount adapter (3) firmly onto the optional
antenna mount (4). Press (5) the antenna into the adapter and
turn it (6) approx. ½ to 1 turn counter clockwise to “catch” the
thread. Turn (7) clockwise 1 to 2 turns and firmly secure the
antenna with the lock screw (1).
)
Do not close the small ventilation hole at the bottom, and do
not attempt to open the antenna.
