Mounting the 8410
The Northstar 8410 differential receiver antenna should be mounted as
high as conveniently possible (but not at the highest point) and as far
away as possible from other antennas. If you have several possible
antenna locations, you may evaluate each by operating the unit with the
DGPS antenna temporarily mounted in each location.
The best location is one providing the lowest “noise” count (atmospheric
impulse noise generated by thunderstorms and other conditions, includ-
ing vessel-generated noise and any on-board interference) and highest
Signal-to-Noise Ratio (SNR). You can view both of these values after you
turn the unit’s power on; see ”Turning the unit on” starting on page 29.
