Mounting Location
This section provides information on determining the best location to mount the V103/113. To use the mounting
template, go to the HGNSS website and navigate to Products/Position & Heading/V103/113.
GNSS Satellite
When considering where to mount the V103/113, consider the following satellite reception recommendations:
 Ensure there is a clear view of the sky available to the V103/113 so the GNSS and SBAS satellites are
not masked by obstructions that may reduce system performance
 The V103/113 computes a position based on the internal primary GNSS antenna element, mount the
V103/113 where you desire a position with respect to the primary GNSS antenna (located on the end
opposite the recessed arrow on the underside of the enclosure)
 Locate any transmitting antennas away from the V103/113 by at least a few meters to ensure tracking
performance is not compromised, giving you the best performance possible
 Make sure there is enough cable length to route into the vessel to reach a breakout box or terminal
strip
 Do not locate the antenna where environmental conditions exceed those specified in Table B-6
Beacon Reception
When using the V113’s internal beacon receiver as the correction source, consider the possible mounting
locations from the perspective of ambient noise within the beacon band.
Keep the following in mind when deciding upon a location with respect to maximizing beacon performance:
 Ensure that the antenna is as far as possible from all other equipment that emits electromagnetic
interference (EMI), including DC motors, alternators, solenoids, radios, power cables, display units,
and other electronic devices.
 If you are installing the antenna on a vessel, mount the Vector compass as high as possible,
considering maintenance and accessibility. In addition, ensure that the antenna is higher than the
highest metal object on the vessel.
 If a radar system is present, mount the antenna outside the path of the radar beam.
