Furuno BBWX4 SiriusXM Receiver Installation Guide
General Information
EMC Installation Guidelines
Furuno equipment and accessories conform to
the appropriate Electromagnetic Compatibility
(EMC) regulations, to minimize electromagnetic
interference between equipment and minimize
the effect such interference could have on the
performance of your system. Correct installation
is required to ensure that EMC performance is not
compromised.
For optimum EMC performance we recommend that
wherever possible:
• Furuno equipment and cables connected to it
are:
- At least 1 m (3 ft) from any equipment
transmitting or cables carrying radio signals
e.g. VHF radios, cables and antennas. In the
case of SSB radios, the distance should be
increased to 7 ft (2 m).
- More than 2 m (7 ft) from the path of a
radar beam. A radar beam can normally be
assumed to spread 20 degrees above and
below the radiating element.
• The product is supplied from a separate
battery from that used for engine start. This is
important to prevent erratic behavior and data
loss which can occur if the engine start does
not have a separate battery.
• Furuno specified cables are used.
• Cables are not cut or extended, unless doing
so is detailed in the installation manual.
Note: Where constraints on the installation prevent
any of the above recommendations, always ensure
the maximum possible separation between different
items of electrical equipment, to provide the best
conditions for EMC performance throughout the
installation.
Water Ingress
Water ingress disclaimer:
Although the waterproof rating capacity of this
product meets the IPX6 & IPX7 standard, water
intrusion and subsequent equipment failure may
occur if the product is subjected to commercial
high-pressure washing. Furuno will not warrant
products subjected to high-pressure washing.
Suppression Ferrites
Furuno cables may be fitted with suppression
ferrites. These are important for correct EMC
performance. If a ferrite has to be removed for any
purpose (e.g. installation or maintenance), it must be
replaced in the original position before the product
is used.
Use only ferrites of the correct type, supplied by
Furuno authorized dealers.
5
Furuno BBWX4 SiriusXM Receiver Installation Guide
Connections to Other Equipment

Antenna Installation
Caution: When installing the antenna, do not cut or alter the antenna cable, or remove the cable connectors.
Two considerations are necessary before installing the antenna. First, finding a suitable mounting location,
and second determine how the antenna will be mounted. There are several in-box mounting options for the
antenna, or accessories can be purchased from marine stores for additional mounting options.
In choosing where to mount the antenna, consider whether you will be securing the antenna from the
underside of the mounting surface, or attaching the antenna to the mounting surface. Also, determine if the
antenna wire will be passed through the mounting surface, or if it will be routed along the surface.
If the distance between the antenna and the BBWX4
Receiver is more than 25 feet, special Shakespeare cable kits
are available. Plan and purchase the appropriate kit before
proceeding (page 16).
Choose a Location
The antenna must be mounted horizontally, and in a location
that is open and has a clear view of the sky.
The antenna must also be mounted away from any metal
objects or other structures that could block the line-of-sight
reception of the satellite signal. The height of the antenna is
not as important as having a clear view of the sky.
The antenna should be mounted a minimum of 1 m
(3 ft.) away from other radio transmitting antennas (such as
VHF or Sideband antennas), and a minimum of 2 m (27 ft.)
from a radar antenna.
Once you have selected a possible mounting location, sight
a full 360
º
circle around the antenna at an elevation angle
of 25º to make sure no obstacles block the antenna’s view
of the sky.

Furuno BBWX4 SiriusXM Receiver Installation Guide
Installing the Antenna
In-box antenna mounting options are surface mount,
low-profile surface mount, or pedestal mount.
Optional mounting options require an extension
mast, or a Shakespeare Style 4720 Rail Mount (each
sold separately).
Always mount the antenna so that it does not
interfere with safe operation of the vessel.
Important: When mounting to a surface using the
low-profile, pedestal, or extension mast mounting
method where the antenna cable will exit above
the mounting surface, orient the base or pedestal
bottom so that the antenna cable exits towards the
rear of the vessel, away from oncoming wind from
normal vessel motion.
The following accessories are available from
Shakespeare:
• SRS-3-KIT - Marine SiriusXM Splitter. Kit to
connect two SiriusXM satellite receivers to
one antenna. Includes three 25’ cables which
