Planning the Optimal Antenna Placement
Proper antenna placement is important to obtain a high-precision GNSS reading. Place the
antennas:
With a clear view of the horizon
Away from other electronics and antennas
Along the vessel’s centerline
You must install the primary antenna along the vessel’s centerline; you cannot
adjust the position readings if the primary antenna is installed off the centerline. Positions
are computed for the primary antenna.
Install on a level plane with a 5.0 m maximum separation (default of 1.0 m) away from radio
frequencies as high as possible.
For optimal performance, orient the antennas so the antennas’ connectors face the same
direction.
Connecting the Antennas to the H220
Connect the following:
Primary antenna to J1000 port on the H220
Secondary antenna to J2000 port on the H220
Thermal Concerns
The power consumption of the H220 receiver will generate heat. Since this may raise
the ambient temperature inside an enclosure, ensure the internal enclosure
temperature does not exceed the maximum operating temperature for the H220.
To achieve maximum dissipation, metal standoffs must be used on all six mounting
points of the H220. Users should implement preferred industry standards for heat
management.
Note:
Thermal design may only be a concern if the integrated product’s maximum design
temperature is expected to be close to that of the H220.
