Vessel construction
The construction of your vessel can have an impact on performance. For example, the proximity of
heavy structures such as a structural bulkhead, or the interior of larger vessels may result in a reduced
signal. The construction materials can also have an impact. In particular, steel, aluminium or carbon
surfaces can impact performance. Before locating equipment with an internal antenna below decks,
or on a steel, aluminium or carbon construction vessel or surface, seek professional assistance.
Prevailing conditions
The weather and location of the vessel can affect performance. Typically calm clear conditions
provide a more accurate position fix. Vessels at extreme northerly or southerly latitudes may also
receive a weaker signal. An antenna mounted below decks will be more susceptible to performance
issues related to the prevailing conditions.
External GNSS (GPS) antenna location requirements
Your product includes a built-in GNSS (GPS) receiver and antenna. It is also possible to connect and
use an external GNSS (GPS) antenna such as the GA150 instead.
When using an external antenna, ensure you follow the location requirements specified in your
external antenna’s installation instructions.
Note:
When using an external antenna you must select the internal antenna in order for it to be used
instead of the external antenna. See the
Switching between internal and external antenna
procedure.
Antenna mounting and EME exposure
Ensure that your VHF antenna is connected to the radio before transmission.
Raymarine® declares a Maximum Permissible Exposure (MPE) radius of 1.8 meters (5.9 ft.) for this
system, assuming 25 watts output to an omnidirectional antenna of 3dBi gain or less.
For watercraft with suitable structures, the antenna base must be at least 3.8 meters (12.5 ft) above
the main deck to meet the MPE for persons up to 2 metres (6.6 ft) tall. For watercraft without such
structures, the antenna must be mounted so that its base is a minimum of 1.8 meters (5.9 ft.) vertically
from heads of all persons.
The antenna must be isolated from the vessel’s metalwork using an insulated (e.g. plastic) mounting
bracket.
Multiple antenna installations
Important additional considerations when installing multiple antennas.
To prevent potential channel interference when installing two or more VHF radios on the same
vessel, ensure that the antennas are located at least 2.4 m (8 ft.) away from each other.
Loud hailer location requirements
To avoid audio feedback, ensure that the loud hailer is at least 3 m (9.8 ft) away from the VHF base
unit and any handset or fistmic at all times. When talking, ensure that the handset or fistmic is
pointing in the opposite direction to the loud hailer.
6.2 EMC installation guidelines
Raymarine® equipment and accessories conform to the appropriate Electromagnetic Compatibility
(EMC) regulations, to minimize electromagnetic interference between equipment and minimize the
effect such interference could have on the performance of your system
Correct installation is required to ensure that EMC performance is not compromised.
Note:
In areas of extreme EMC interference, some slight interference may be noticed. Where this occurs
the product and the source of the interference should be separated by a greater distance.
For optimum EMC performance we recommend that wherever possible:
