Raymarine AIS350 Installation Instructions Manual page 51

Important: The main requirement of the intended location for the
GPS antenna is that it gives a good direct line of site to the entire
sky, right around the horizon.
Ensure that the intended 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 unit, 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.
