Antenna Systems - Simrad MX610 Operator And Installation Manual

Antenna systems

Several Itype-approved antenna models can be used with the MX610/MX612, namely:
• MX521A/B - GPS/DGPS smart antenna (NMEA 0183 interface). - Standard
• HS80/HS80A or MX575C/D D/GPS compass unit (N2K or NMEA 0183 interface) - Option
• GS70 - GPS/WAAS smart antenna (N2K interface) - Option
As a general rule, the antenna unit must be located in the open where it will have a good
view of the sky aournd it. It must also be located away from large metal objects that can block
the GPS signal as well as influence the operation of the antenna unit.
Antenna mounting guidelines
• Install the antenna where it has a clear view of the sky around it
• Keep it away from large metal structures like the main mast or overhead railings
• Stay away from high-powered transmitter antennas like SSB, VHF and other radio transmitter
antennas
• Mount the GPS antenna low to avoid excessive position and speed errors while underway
• Locate the antenna at least 10 meters away and below the transmitting beam of the radar
and INMARSAT antennas.
¼ Note:
Powerful Xenon search lights emit strong RF radiation that could interfere with GPS re-
ception. We recommend providing extended horizontal distance separation from the MX61x
antenna unit. Minimum vertical separation should be 3 meters above the light. Please refer to
manufacturer's instruction for more details.
