Chapter 10-6 CE33 Installation and service
10.5 Installation of antenna
The antenna must be placed in a position where tall
constructions, 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 inteference, such as radar, satcom,
etc. If installing the GPS antenna close to other anten-
nas it must be placed either above or below the radia-
tion beams. There is full coverage down to 20° below
the horizon.
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.
1/2 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.
