Chapter 3: Installing the GPS Antenna

The RS 12 package contains the following items:
1. Low profile GPS Receiver, with 10 m (33 ft) cable
2. Flush mount gasket
3. Mounting studs (x2) and thumb nuts (x2)
4. Pole mount kit *
Note:  

* If you intend to mount the receiver on a pole, you will need to obtain a suitable 

pole with 1 inch 14 TPI thread.

3.1 Selecting the Mounting Location

The RS12 can be mounted on a pole or flush mounted on a suitable horizontal 
surface. 

Receiver Location

The RS12 receiver is designed to receive the signals emitted from satellites in a 
direct path. It should be mounted:
• On a horizontal surface.
• In a location that is open and clear of any obstructions (such as masts, search 

lights, or other structures) that could block line-of-sight reception of signals. 

• As low as possible: the height of the receiver is not as important as it having a 

clear view horizon to horizon for optimum signal reception. In fact, the lower 
the unit can be mounted and have a clear view to satellites, the better. The 
more stable the unit, the more effectively it will track satellites low to the hori-
zon.

Do NOT mount the receiver up a mast, as the receiver will swing with the boat, 

leading to significant COG/SOG errors.

• As far as possible from any sources of interference: the receiver should be sep-

arated by at least 1 m (3 ft) from other antennas and electronic equipment. It 
should not be mounted in the direct path of a radar’s beam. 

When mounting the receiver flush to a surface: 
• select an area that allows access to the underside of the mounting surface
• avoid areas where the receiver might be stepped on or tripped over
