Antenna Location Requirements; Product Dimensions - Raymarine GA150a Installation Instructions Manual

3.5 Antenna location requirements

The antenna can be used to improve the reception of your
MFD's built-in GNSS (GPS / GLONASS) receiver. Do NOT
connect any other antenna to the MFD's GA150 connector.
The 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 antenna must be mounted in a location that
provides a good direct line of site 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.
Antenna Mounting & EME Exposure
For optimal radio performance and minimal human exposure to
radio frequency electromagnetic energy, make sure the antenna
is:
• connected to the radio before transmitting
• properly mounted
• located where it will be away from people
• located at least 1.5 metres (5 feet) from the radio's main unit
