External GPS Antenna (required)
Consider the following location and connection requirements:
- The GPS antenna should be positioned with an unobstructed
view of the sky.
- The GPS antenna is rated IP67 and UV stable for external
installation.
- Do not place the GPS antenna near or in the path of radar, HF
and/or high power satellite communication (such as Iridium Go)
antennas.
- You cannot use another GPS or any other NMEA device
to provide a GPS position to the M1. Class B AIS SO-TDMA
transponders are required by international regulations to use
their own GPS.
- You may use the M1 to share GPS position data to other
devices over NMEA 2000, 0183 or WiFi.
- The antenna cable is terminated with an SMA connector to
facilitate easy routing through holes and openings. Do not cut
the cable without the correct tools to crimp on a new connector.
HINT - Use the GPS Status screen in the Onboard App or handset
to view the satellite signal strengths and determine the best
location for mounting the external GPS antenna.
CAUTION - The Vesper Marine GPS antenna is specifically
designed for use with Vesper Marine devices. Use of a different
GPS antenna may damage the M1 hub and void the warranty.
