GA200
GNSS (GPS
/ GLONASS)
Antenna
Product overview
The GA200 is an external antenna, suitable for improving the
reception of the internal GNSS (GPS / GLONASS) receivers of
compatible MFDs, AIS devices, and VHF radios.
Note:
The GA200 is not a receiver. It is an antenna only, and
requires a connected compatible MFD, AIS device, or VHF radio
that features an internal GNSS (GPS / GLONASS) receiver.
Important:
If you are replacing a GPS antenna supplied with
an older AIS receiver or an AIS700 with an early (low) serial
number, please be aware that the mounting diameter (cutout) of
the GPS receiver has changed, from Ø44 mm to Ø60 mm.
The GA200 has the following features:
• 10 m (33 ft.) fitted cable.
• Low power consumption.
• Surface or pole mountable.
• Compatibility with GPS, GLONASS, Beidou, and Galileo satellite
systems.
Note:
When the Beidou GNSS system becomes available, a
GA200 MUST be used in order to obtain reception. Your MFD,
AIS device, or VHF radio may also require a software update to
enable support of the Beidou system.

GNSS antenna location requirements
Important:
If you are replacing a GPS antenna supplied with
an older AIS receiver or an AIS700 with an early (low) serial
number, please be aware that the mounting diameter (cutout) of
the GPS receiver has changed, from Ø44 mm to Ø60 mm.
The GNSS antenna can be mounted either on a flat horizontal
surface or on a suitable pole.
• If you intend to surface mount the antenna, ensure you have
access to the underside of the mounting surface.
• If you intend to pole-mount the antenna, the pole needs to have
a 1 inch 14 TPI thread.
Important:
The GNSS antenna must be mounted in a location that provides
a good direct line-of-sight to the entire sky, around the horizon.
Ensure that the selected mounting location is:
• Open and clear of any obstructions (such as masts, search lights,
or other structures) that could block line-of-sight to the sky.
• As low as possible, to keep the antenna as stable as possible.
The more stable the antenna, the more effectively it will track
satellites and provide stable data.
• As far as possible (at least 1 m (3 ft)) from other antennae and
electronic equipment.
Do NOT mount the antenna:
• In any area where it could be stepped on or tripped over.
• Up a mast. This will cause the antenna to swing and give
significant errors in position data.
• In the direct path of a Radar beam.
• In an engine room.
Antenna cable extension
The GNSS antenna is supplied with a fitted 10 m (33 ft.) cable. The
length of the antenna cable can be extended if required.
The antenna cable length can be extended by up to 10 m (33 ft.),
giving a total maximum cable length of 20 m (66 ft.)
RG58-Type 50 ohm coaxial cable and reliable connectors (offering
protection against water ingress) must be used when extending
the antenna cable.
Note:
Extending the cable length by more than the
recommended maximum length will result in signal degradation.
Cable bend radius
Throughout the cable run, maintain a maximum cable bend radius
of 50 mm (2 in.).
