Mounting the Receiver
Please read through these instructions thoroughly before
attempting installation. Make sure you completely understand
these instructions before you begin. When in doubt, seek
professional assistance.
The following additional items are needed or optional
to complete the installation of your DGPS 53:
• Antenna mount— Since antenna mounting
locations and methods vary, you will need to obtain
an antenna mount to install the DGPS 53. The
receiver base fits a standard 1-inch, 14 threads-per-
inch mount. Check with your GARMIN dealer or a
marine supply retailer for this item.
• On/Off switch (optional)— Power to the
receiver may be controlled by an on/off switch, such
as an accessory switch on the control console.
Check with your GARMIN dealer or a marine/
electric supply retailer for this item.
• GARMIN 60’ Power/Data Cable— for cable
installation lengths greater than 30’. Part number
010-10284-00
It is recommended that the system be temporarily
hooked up with the wiring and the unit placed at the
desired installation location. Then, check operation with
potential interfering equipment turned on and off. (For
example, other electronic equipment, fan motors, engine
ignition, alternators, generators, radars and VHF radio
transmissions can be sources of interference.)
Position the receiver so that the clearest possible view
of the sky and horizon in all directions is obtained. Avoid
mounting the antenna next to large areas of conductive
material (metal, aluminum, etc.) as this may cause poor
signal reception. The DGPS 53 is supplied with a 30 feet
power/data cable. When routing the wiring to the DGPS
53, avoid routing the cable near the vessel’s alternator or
ignition system components or parallel to other power
lines.

Note: As a general rule,
mount the receiver at least
three feet from all other
antennas and the vessel’s
electrical system components
(alternator/ignition system).
