Radar system overview
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 (000-
10418-001) is not shipped with an RI10 or RI11 interface.
