Radar Transmit Emissions
Note: Broadband 3G™ and 4G™ Radar are the second generation marine recreational radar
from Navico that has Human Exposure Level RF Radiation of the Radar Transmitter outside
the Radome well below the general public safety emission level of 1 mW/cm2 . This means the
radar can be mounted safely in locations impossible with other pulse radars.
2 |
Note: If a pulse radar and Broadband Radar are mounted on the same vessel, do not transmit
simultaneously as excessive interference is possible.
The Broadband Radar will not trigger X Band radar transponders, beacons, and
SARTs due to the low output power and signal properties.

Congratulations on your purchase of the latest technology available in recreational marine
radar. The special features designed into this radar are:
• “Revolutionary improvement in situational awareness” - provides unprecedented ability to
distinguish hazards and other objects
• Radar is nally easy enough for casual users – identi es targets clearly with out complicated
tuning adjustments
• Navigation with unparalleled resolution and clarity at close ranges, where traditional radar
completely obscures targets
• “Start faster, go longer” - 100% solid state design – no powerful microwave transmitter
required! – provides InstantOn™ power up capability and low power consumption
• Eliminate the 2-3 minute warm-up time typical of traditional radars
• Conserve power with a standby drain less than one tenth of the best existing radars –
especially great for sailboats and smaller power boats
• No expensive magnetron replacement is ever required
• “Incredibly approachable” - practically imperceptible transmit emissions are extremely safe,
allowing you to mount it anywhere
th
• Less than 1/5
proximity to passengers
• Compatible with a wide range of Navico multi-function displays and heading sensors
the transmitted emissions of a mobile phone, can be safely mounted in
Firstly it is solid state – i.e. the transmitter is a semiconductor device, not based on magnetron
technology. Secondly, it transmits a 1ms long signal of increasing frequency, rather than a short
duration pulse. Thirdly, it measures the distance to a target not by timing the returned echoes,
but by measuring the di erence between the current transmitted frequency and echoed
frequency. Hence FMCW – Frequency Modulated Continuous Wave.
The building up of the image over 360 degrees and the processing of the radar data is the same
as for a magnetron radar.
The scanner transmits a ‘rising tone’ (Tx wave) with linearly increasing frequency. The wave
propagates out from the transmitter retaining the frequency it had when it was transmitted. If
it re ects o an object, it will return to the receiver, still at the frequency it had when originally
transmitted.
Meanwhile, the transmitter continues to output an increasing frequency.
The di erence between both the currently transmitted and received frequencies, coupled with
the known rate of frequency increase, allows a time of ight to be calculated, from which distance is calculated.
Additional bene ts of FMCW radar are:
Safety
• low energy emissions. 1/5th of a mobile phone
• safe operation in anchorages and marinas
• instant power up. No warm up required
Short range performance
• broadband radar can see within a few meters of the boat, compared to pulse radars,
which can not see closer than 30 meters
• higher resolution clearly separates individual vessels and objects
• Up to ve times better sea and rain clutter performance
Low power
• suitable for small boats and yachts
• easier installation with lighter cabling and smaller connectors
• great for yachts on ocean passage
Instant power-up
• conventional radars take 2-3 minutes to warm up the magnetron: Safety – 2 minutes is a
long time if you are concerned about collision.
• convenience – switch it on and use it.
Easy to use
• no constant adjusting required to obtain optimum performance
• no re-tuning between ranges. Means fast range change at all ranges
The Broadband Radar is a state of the art navigation aid. It provides outstanding radar
performance without the limitations of conventional pulse radars such as: dangerous
high power microwaves, standby warm up time, 30 m blind spot (mainbang), high power
consumption and large open arrays (which is what would be required to obtain the same
image quality at shorter ranges).
The Broadband 3G™ radar has an e ective range from 200 ft to 24 nm, whereas the Broadband
4G™ radar has an e ective range from 200 ft to 36 nm (target dependent).
The operating power consumption for the 3G is 18 W, with a stand-by power consumption of
2 W. The 4G operates on 20W, and has a standby consumption of 2.9W.
The system consists of: radar scanner, an interface box (not included with Lowrance 3G USA
model) and an interconnection cable. The scanner is housed in a dome of similar size to most
2 kW radars on the market.
The RI10 interface box is used to connect displays, power and heading information if MARPA or
chart overlay are required (Heading sensor not included). The RI10 has a SimNet (Simrad NMEA
2000) connector for heading input. The RI10 is included in all 4G kits.
The RI11 interface box is used to connect to earlier NX series displays using a serial connection.
A Y-cable may be used to add heading input for MARPA via NMEA0183.
The 3G kit may be ordered with either interface box, however the Lowrance USA model (00010418-001) is not shipped with an RI10 or RI11 interface.

Choose the scanner location
The radar’s ability to detect targets greatly depends on the position of its scanner. The ideal
location for the scanner is high above the vessel’s keel line where there are no obstacles.
A higher installation position increases the radar ranging distance, but it also increases the
minimum range around the vessel where targets cannot be detected.
When you’re deciding on the location, consider the following:
The length of the interconnection cable supplied w your radar is usually su cient. If you think
you’ll need a longer cable, consult your dealer before installation. Optional cable lengths are 10
m (33 ft), 20 m (65.5 ft) and 30 m (98 ft).
If you mount the scanner on a pedestal or base, ensure that rain and sea spray can drain away
rapidly, and the breather hole in the base can operate .
The scanner is usually installed parallel to the line of the keel.
DON’T DO THIS!
• DON’T install the scanner too high up (eg at the top of a mast), which may cause
degradation of the radar picture over short ranges
• DON’T install the scanner close to lamps or exhaust outlets. The heat emissions may
damage the dome. Soot and smoke will degrade the performance of the radar
• DON’T install the scanner close to the antennas of other equipment such as direction
nders, VHF antennas, GPS equipment, as it may cause or be subject to interference
• DON’T install the scanner where a large obstruction (such as an exhaust stack) is at the
same level as the beam, because the obstruction is likely to generate false echoes and/or
shadow zones
• DON’T install the scanner where it will be subjected to strong vibrations because these
vibrations could degrade the performance of the radar
• DON’T install the scanner such that boat electronics with switch mode power supplies
(such as sh- nders and chart plotters) are in the beam of the antenna
• DON’T install the scanner directly on to a large at roof area. Use a pedestal to elevate the
scanner for radar beams to clear roof line (see “Considerations for direct roof mounting” on
page 8)
Dual Radar installation - Broadband Radar and Pulse Radar installation:
For dual radar installations, ensure Broadband Radar is not installed in the beam of the pulse
radar at any time.
Minimum distance to install near the
ships compass is 0.7 m (3.3 ft).
If possible ensure that the location site
provides the scanner with a clear view
all round the vessel.
Do not install the Broadband Radar on the same
beam plane as a conventional pulse radar. A pulse
radar must be set to STBY or OFF any time the
Broadband Radar is being operated.
Installations on power boats that have a steep
planing angle, it is recommended to tilt the scanner angle down at the front. (Beam angle is 12.5°
either side of center).
Considerations for direct roof mounting
When deciding a suitable mounting location for the Broadband Radar, be aware that the vertical radar beam extends to 25° either side of horizontal. With 50% of the power projecting in a
beam 12.5° o horizontal. If the radar beams cannot clear the roof line, this will decrease performance of the radar. Depending on the size of the hard top of the vessel, it is recommended
not to mount directly on to the surface, instead elevate the scanner to allow the radar beams
to clear the roof line. Below are guide lines on heights above the hard top.

The above illustrates an installation with the Broadband Radar mounted directly on to a large
hard top. This installation could su er decreased performance as the radar energy is either
re ected or absorbed by the hard top.
Note: Where the mounting surface is constructed of any form of metal you must elevate
the dome so that the beam has complete clearance, else performance will be severely
impaired.
Use the supplied mounting template and tape it securely to the chosen location.
Before drilling, check that:
• you have oriented the mounting template correctly so that the front of the scanner unit will
face the front of the vessel
• the thickness of chosen location is not more than 18 mm (0.7”) thick. If the location is thicker,
longer bolts than those supplied will be required
• the four bolts supplied are M8 x 30 mm. If you need to use longer bolts make sure they are
marine grade stainless steel and allow for minimum of 8 mm (0.3”) and maximum of 18 mm
(0.7”) of thread contact
1. Use a 9.5 mm (3/8”) drill bit to drill the four holes where shown on the mounting template
2. Remove the mounting template
3. Connect the scanner interconnection cable (see “Connect interconnection cable to the
scanner” on page 11 )
4. Route the connection cable through the cable retention channel
6. Position the scanner carefully over the bolt holes so that they are aligned
7. Place a lock washer and a plain washer onto each bolt, as shown
8. Insert bolt into drill hole and locate into scanners threaded mounting holes and tighten securely
Note: The torque settings for the mounting bolts are 12 Nm – 18 Nm (8.9 lb ft – 13.3 lb ft)
The scanner interconnection cable connects the scanner to the RI10 interface box (or Lowrance
HDS via and ethernet adapter cable - 3G U.S only). The cable connects to the scanner using a
14 pin connector.
• Protect the connectors when pulling cable through the boat and avoid putting strain on
to the connectors
• The interconnection cable is 9 mm in diameter. A 14 mm hole will be required in order
for the RJ45 connector to pass through (Interface box end) or 24 mm for the scanner end
connector
• Run the interconnection cable between the scanner and the location of the radar interface box
• Insert cable connector on to the male 14 pin plug on the scanner
• Take care to align the connector correctly to avoid bending the pins. Secure the locking
collar by rotating clockwise until it clicks
• Feed and secure the cable into the cable retention channel

Note: Lowrance HDS units sold in the USA do not require an interface box and the scanner
connects directly to the display or Ethernet switch. If chart overlay or MARPA are required for
Lowrance HDS USA then an RI10 Interface box and heading sensor are required
Adding MARPA and / or Chart Overlay
To add MARPA and/or Chart overlay, it is essential to use a heading sensor with an output speed
of 10 Hz. The Heading sensor needs to be a rate gyro stabilized compass or better
You can use a Heading Sensor with an NMEA 0183 or NMEA2000 output source
You must use a Radar Interface box to connect the heading data to the radar system - this is
because MARPA calculations are done by the radar:
• If your heading source is NMEA0183, use an RI11 Interface box for Simrad NX installations,
or an RI10 Interface box with an AT10HD converter for all other installations. The AT10HD
converts NMEA0183 to SimNet / NMEA2000 (only heading information is converted)
• If your heading source is NMEA2000 or SIMNET use an RI10 Interface box.
The Broadband Radar can operate on 12 or 24 V DC systems. The Broadband Radar requires +V
DC to be applied on the yellow power on wire in order to operate. This can be achieved in one
of three ways:
1. Common the red and yellow wire together, and connect to a fused switch. Radar will power on
in standby when power is applied. When switch is o , radar will draw no power
2. Use ignition or install a switch that will provide power to the yellow wire. (It is recommended to
use a 5 amp fuse or breaker). The radar will turn on when switch is activated. When the switch
is o , the radar will draw minimal power (~1mA)
3. Connect the yellow wire to external wake up of suitable display such as NSE, NSO, or NSS. The
radar will turn on when the display is turned on. The display must be set to ‘Master’ under
Power Control. When the display is o , the radar will draw minimal power (~1mA)
Before connecting power to the system:
!
!
!
• make sure the scanner has been installed and is secured.
• make sure the radar interconnection cable is connected to the radar.
• if using the Radar Interface Box make sure all connections have been made
to the display.
For systems using an RI10 radar interface box:
• Connect the red wire to power positive 12 or 24 V DC. Use a 5 amp fuse or breaker
• Connect the yellow wire to power source that will turn on the system (see above)
• Connect the black wire to power negative

Setup and Con guration
Setup and con guration of the Broadband radar has been simpli ed compared to traditional
pulse radars. There is no zero range adjustment (time delay), no warm up time, and no burn in
required.
The following sections cover the available adjustments. Note that the menu examples used are
from the Simrad NSE. While these di er aesthetically from the Lowrance interface, the content
is essentially the same.
Entering radar setup on your display
Enter radar installation by pressing MENU > SETTINGS > RADAR > INSTALLATION.
Radar Status
Software Version
Check to make sure you have the latest software. Check website for the latest version.
Serial Number
Take a minute to write down the serial number of the radar.
MARPA Status
The MARPA status can identify if a heading sensor is on the network and that the radar is
receiving heading information essential for MARPA calculations.
Reset Device ID
NSS and HDS displays only support one radar on the network. Should a radar be connected,
that has been previously connected to a dual radar network in the past, it may not be detected
by the display because it has an incorrect Device ID. To resolve this problem use the following
procedure, which must be performed with only one radar on the network.
From the Radar Status page. Select “Reset device ID....” then follow the on screen prompts;

Page 22
Adjust bearing alignment...
Adjust the heading marker. This is to align with the heading marker on the screen with the
center line of the vessel, this will compensate for any slight misalignment of the scanner during
installation. Any inaccuracy will be evident when using MARPA or chart overlay.
Point the boat to the end of a head land or peninsula. Adjust the bearing alignment so the
heading line touches the end of the same head land or peninsula.
Adjust local interference reject...
Interference from some onboard sources can interfere with the Broadband radar. One symptom
of this could be a large target on the screen that remains in the same relative bearing even if
the vessel changes direction. Choose from Local interference rejection LOW, MED or HIGH.
Default is LOW.
Adjust antenna height...
Set the radar scanner height. The Radar uses this value to optimize sea clutter performance.
Note: It is very important to get the antenna height con gured correctly as this will a ect the
sea clutter function. Do not set the height to 0.
Sidelobe suppression...
Note: This control should only be adjusted by experienced radar users. Target loss in harbour
environments may occur if this control is not adjusted correctly.
Occasionally false target returns can occur
adjacent to strong target returns such as
large ships or container ports.
This occurs because not all of the
transmitted radar energy can be focused
into a single beam by the radar antenna, a
small amount energy is transmitted in other
directions.
This energy is referred to as sidelobe energy
and occurs in all radar systems.
The returns caused by sidelobes tend to
appear as arcs:
When the radar is mounted where there are metallic objects near the radar, sidelobe energy
increases because the beam focus is degraded. The increased sidelobe returns can be eliminated
using the Sidelobe Suppression control in the Radar installation menu.
By default this control is set to Auto, and normally should not need to be adjusted. However
if there is signi cant metallic clutter around the radar, sidelobe suppression may need to be
increased. The control should be adjusted as follows:
1. Set Radar range to between 1/2nm to 1nm and Sidelobe Suppression to Auto
2. Take the vessel to a location where sidelobe returns are likely to be seen. Typically this would
be near a large ship, container port, or metal bridge
3. Traverse the area until the strongest sidelobe returns are seen
4. Change Auto sidelobe suppression to OFF then select and adjust the sidelobe suppression
control until the sidelobe returns are just eliminated. You may need to monitor 5-10 radar
sweeps to be sure they have been eliminated
5. Traverse the area again and readjust if sidelobes returns still occur
6. Exit the installation menu

To start the radar:
From the radar screen select the Transmit button.
RI10 heading source selection:
The RI10 receives heading via SimNet or NMEA2000 network and transmits this data to the
radar, where MARPA processing is performed.
For Simrad installations with more than one SimNet heading source the RI10 will use the
Simrad group source. The source used by the Simrad group can be viewed or changed via an
NSE / NSO / NSS display in the Settings>Network>Sources… menu.
Dual Radar setup:
For B&G Zeus and Simrad NSO and NSE displays it is possible for two radars to be connected
to the network and viewed simultaneously on one display. At time of installation radar source
selection needs to be performed as described below.
1. Power up the system including both radars
2. On any display, the rst radar ever detected by the display will be used as the source for all chart
and radar panels. This source will be used by default for every system power-up thereafter,

6. The radar source selection is not global, so will only apply to the display on which the
source was selected. The radar source will need to be setup for each display on the network.
Once the radar sources have been set up they will be retained for every system power-up until
changed by the user
Dual Range setup (Broadband 4GTM Radar only):
With a Simrad NSE display connected to a Broadband 4G™ radar, it’s possible to run the radar
in dual range mode. This allows two radar panels to be veiwed simultaneously, operating at
di erent ranges but with all image data supplied by one 4G scanner. Each displayed radar panel
can track up to 10 MARPA targets - ability to acquire targets is range dependant.
Setup of Dual Range is identical to that used for Dual Radar setup, except that a 4G radar will
show two instances in the sources list; an A channel and a B channel.

Note: two 4G radars on the same system will show four radar sources (two A and B channels).

Maintenance
Clean the radome using soapy water and a soft cloth.
Avoid using abrasive cleaning products.
Do not use solvents such as gasoline, acetone, M.E.K etc. as this will damage the dome surface.
After years of use the drive belt may have to be replaced.
The transmitter in the Broadband Radar is solid state and will not require regular replacement,
unlike the magnetron found in conventional pulse radar.
