91-102469 Lars Thrane Pole Bracket Mount, 1.5-2.5in pipe(Ø38.8-63.5mm), w/ Cable Hose, for Antenna

The Bracket Mount, suitable for 1.5 to 2.5in(38.8 to 63.5mm) pipe, Antenna Unit interfaces to a pipe of maximum 2.5in (63.5 mm), measured outer diameter.

This pack includes: 1pce Bracket Assembly, and 1pce protective Cable Hose(part# 91-102470) The Cable Hose can be ordered separately from Lars Thrane A/S on the following P/N: 91-102470 Cable Hose (standalone).

Apply self-volcanic tape on the N connector and cable to protect against saltwater and corrosion and use the recommend Cable Hose

Always fasten the Bracket Mount, Antenna Unit (1.5” to 2.5” pipe) to the pipe, before installing the LT-xxxx Antenna Unit (the antenna unit and bracket mount are fastened together by the thread lock).

Remember to secure the pinot screw(grub screw) after the antenna unit has been fastened.

The torques are specified in Figure 28 on page 26 of the user instruction manual.

ACCESSORIES – NOT INCLUDED – Below are not part of this system and must be ordered separately:

GENERIC TERMINAL-ANTENNA INFORMATION

The L-xxxx 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-xxxx 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-xxxx 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-xxxx Antenna Unit must be obeyed. Figure 13 is illustrating how the LT-xxxx 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-xxxx Antenna Unit may be reduced, with no impact on the antenna performance. The performance of the LT-xxxx Antenna Unit should be validated when the LT-xxxx system is installed.
