It is only the LT-3130 Antenna Unit marked with HVIN 2.00 (Unit Label) or newer that can
be used for the LT-3100S GMDSS Satellite Communications System.
The LT-3100S GMDSS software will check the antenna unit during power up and the system will not be operational, if connecting a legacy LT-3130 Antenna Unit.
The LT-3130 Antenna Unit is designed for outdoor mounting and connected to the LT-3110S Control Unit via a coaxial cable.
In order to avoid breaking the LT-3130 Antenna Unit N connector (female), it is important not to use tooling when connecting and fastening the coaxial cable N connector (male) to the antenna unit. The coaxial cable N connector thread nut must be fastened by hand only.
The LT-3130 Antenna Unit has an N connector (N-Female) mounted and centered, exit point at the bottom of the antenna.
ACCESSORIES – NOT INCLUDED – Below are not part of this system and must be ordered separately:
TO ORDER – Control Unit Flush Mount for Console
• 91-100772 Flush Mount, for the Control Unit
LT-3130 TERMINAL ANTENNA INFORMATION
The LT-3130 Antenna Unit should be mounted with free line of sight to the Iridium satellites for best possible performance.
The best location will typically be at the top of the lantern mast, where there are no obstructions blocking the Iridium satellite link. The LT-3130 Antenna Unit is designed to maintain a communication link to the Iridium satellites in all weather conditions.

TO ORDER – Cable, Connectors and Tooling
The following cable and connector parts are not part of the basic system and must be ordered separately:
• 91-100768 Aux Cable, 3m
• 91-101183 Coaxial cable Ø4.9mm, 10m
• 91-101184 Coaxial cable Ø4.9mm, 25m
• 91-101137 Coaxial Cable Ø10.3mm 10m
• 91-101138 Coaxial Cable Ø10.3mm 25m
• 91-101139 Coaxial Cable Ø10.3mm 50m
• 91-101140 N Conn. (male) for Coaxial Cable Ø4.9mm
• 91-101186 N Conn. (male) for Coaxial Cable Ø10.3mm
• 91-101187 Crimping Tool for Coaxial Cable Ø4.9mm
• 91-101188 Crimping Tool for Coaxial Cable Ø10.3mm
Coaxial cables are delivered with one fixed N connector (outdoor mounting), another loose N connector and crimp parts comes with the cable. It is required to use an appropriate crimping tool for attaching the loose N connector.
Antenna Mounting and installation considerations:
• Mount the unit vertically (with the N connector pointing down)
• Mount the unit with free line of sight to the Iridium® and GNSS satellites. Make sure that the unit can receive signals from the Iridium® and GNSS satellites
• Mount the unit on a rigid structure with a minimum of exposure to vibration and shock
• Mount the unit using either the Bracket Mount or Pole Mount provided by Lars Thrane A/S
• Mount the unit outdoor with an ambient temperature between -40°C to +55°C (-40°F to +131°F)
• Mount the unit with a minimum angle of 10 degrees towards a radar antenna (above or below) and keep a minimum distance of 2.5 m (8 ft)
• Mount the unit at least 1 m. (3 ft.) away from radio transmitting antennas (VHF, UHF, MF-HF)
• Mount the unit away from Inmarsat and transmitting VSAT antennas
The LT-3130 Antenna Unit must be installed outside the radar main beam. Typically, this is in the order of 10 degrees. To avoid near field antenna coupling, a minimum distance of 2.5 m (6 ft) between the radar antenna and the LT-3130 Antenna Unit must be obeyed. Figure 13 is illustrating how the LT-3130 Antenna Unit should be mounted to avoid interference from radars.
IMPORTANT: Failing to obey the specified installation conditions will void the warranty. However, depending on the specific radar frequency and power level, the separation distance between the radar and the LT-3130 Antenna Unit may be reduced, with no impact on the antenna performance. The performance of the LT-3130 Antenna Unit should be validated when the LT-3100 system is installed.
