2.3 Installing the RC435 External GPS Antenna
The RC435 GPS Antenna is designed to receive the signals emitted from
the satellites in a direct path.
The GPS Antenna should be mounted in an open location with a clear
view of the sky. GPS systems rely on stability to track satellites therefore
the height of the receiver is not as important as having a clear horizon to
horizon view.
The external GPS Antenna can be mounted on a pole or surface mounted.
When planning the location for the unit, consider finding a convenient
pathway for running the cable that connects the GPS Antenna to the
display unit. Ideally the cable should be run so that it is hidden from view
and, if possible, be in a direct path to the point of connection. It is
important to keep the cable separated as far as possible from other
shipboard cables to prevent interference.
Note:
Mounting on the mast of a sailboat is not recommended.
Failure to properly mount the antenna can result in poor performance.
CAUTION:GPS ANTENNA LOCATION
When mounting the GPS Antenna flush to a deck surface, avoid
areas where the unit could be stepped on or tripped over.
Special Instructions for Installing the RC435i
Because its GPS antenna is internal, the RC435i should be mounted in an
open location with a clear, unobstructed view of the sky.
•
The RC435i should never be mounted below deck.
•
The RC435i should never be panel (flush) mounted.
The optional Panel Mounting Kit listed in
Section 2.2, Unpacking
and Inspecting the Components
, applies to the RC435 with External
Antenna only.
The RC435i must not be flush mounted into the dash of a boat or into a
NavPod style instrument housing. The RC435i must be mounted in a
relatively open cockpit with its included yoke/trunnion mount bracket.
The boat can have a bimini or a dodger, but not a hardtop.
Note:
If you want to flush- or pod-mount the unit, have a hardtop, or are
otherwise concerned about giving the upper-rear portion of the unit's
chassis a clear view of the sky, you should opt for the standard RC435
with its external antenna.
Failure to properly mount the chartplotter can result in poor performance.
