Page 50: Figure 3-10: Free Mast Length And Bracing For A Tall Mast
Site preparation 3..2.6.2 Mast length and diameter The placement of the ADU must ensure a rigid structural connection to the hull or structure of the ship. Parts of the ship with heavy resonant vibrations are not suitable places for the ADU. A small platform or short mast shall provide rigid support for the ADU fastening bolts and a rigid interface to the ship.
Page 51: Table 3-2: Mast Dimensions Without Braces
3..2.6.3 SAILOR 900 VSAT ADU mast length The below tables show the minimum dimensions for a SAILOR 900 VSAT ADU mast with and without stays or wires. Note that the values are only guidelines - always consider the environment and characteristics of the ship before deciding on the mast dimensions.
Page 52: Interference
The ADU must be mounted as far away as possible from the ship’s radar and high power radio transmitters, because they may compromise the ADU performance. RF emission from radars might actually damage the ADU. The SAILOR 900 VSAT ADU itself may also interfere with other radio systems. 3..2.7.1 Radar...
Page 53: Figure 3-11: Interference With The Vessel's Radar
(below approximately 10 m) between radar antenna and the SAILOR 900 VSAT ADU. Therefore it is recommended to ensure as much vertical separation as possible when the SAILOR 900 VSAT ADU has to be placed close to a radar antenna.
Page 54: Table 3-6: Minimum Radar Separation, S-Band
Radar interference Even at distances greater than “d min.” in the previous section the radar might still be able to degrade the performance of the SAILOR 900 VSAT system. The presence of one or more S or X-band radars within a radius up to 100 m may cause a minor degradation of the Ku-band connection.
Page 55: Figure 3-12: Recommended Distance To Transmitters (M) For Frequencies Below 1000 Mhz
Site preparation 3..2.7.4 GPS receivers Good quality GPS receivers will work properly very close to the ADU - typically down to one meter outside the main beam. 3..2.7.5 Other transmitters See the following figure for minimum recommended distance to transmitters in the frequency range below 1000 MHz. Figure 3-12: Recommended distance to transmitters (m) for frequencies below 1000 MHz 98-133966-G1...
Page 56: Other Precautions
Site preparation 3.2.8 Other precautions 3..2.8.1 Condensation and water intrusion If possible, install the radome such that direct spray of seawater is avoided. In some weather conditions there may occur condensation inside the radome. The drain tube is designed to lead any water away from inside the radome.

Page 267: A.3 Vsat Lnb Data Sheet (Physical Lnb)
The following table shows the data of the LNBs which are fitted in the ADU. The SAILOR 900 VSAT is designed to make any Ku Band frequency in the range of 10.7 GHz to 12.75 GHz available to a VSAT modem by allowing the user to select the LNB LO of his choice – without having to exchange the physical LNBs in the ADU.
Page 268: Vsat Lnb Data Sheet (Physical Lnb
LO must be in the range of 9.6 GHz to 11.3 GHz (Optimum values are 9.75 GHz and 10.75 GHz as these match the physical LNB values). All VSAT modems that can be used with SAILOR 900 VSAT use this approach for selecting the LO frequency, except a COMTECH modem with ROSS server. A COMTECH modem with ROSS server reads switching signals by means of a data connection instead of using voltage and tone signals.

Page 311: Appendix F Grounding And Rf Protection
Grounding and RF protection Why is grounding required? F.1.1 Reasons for grounding Grounding the SAILOR 900 VSAT system is required for at least two reasons: • Safety: Lightning protection of persons and equipment. • Protection: ESD (ElectroStatic Discharge) protection of equipment.
Page 312: Grounding Recommendations
Grounding Recommendations Grounding Recommendations F.2.1 Grounding the ACU The ACU should be grounded to the ship/hull. For this purpose you may use a short ADU cable and a grounding kit. Further, the ACU must be grounded at its grounding stud in order to ensure proper grounding if the short ADU cable is disconnected.
Page 313: Grounding The Adu
Alternative grounding for steel hulls F.2.2 Grounding the ADU You can ground the ADU to the ship/hull via one or more of its mounting bolts. Make sure to remove painting, dirt, grease etc. at the mounting holes in order to make good electrical contact to the hull. Use serrated washers when securing the mounting bolts and seal the joint with protective coating to avoid corrosion.
Page 314: Grounding The Adu
Alternative grounding for steel hulls The ground connection can be established either at the hull (recommended) or at a dedicated RF ground if available (alternative). However, bear in mind that the ADU ground Important connection is to be made at the same electrical ground potential as the ACU (see Grounding the ADU).

Alternative grounding for fibre glass hulls Alternative grounding for fibre glass hulls F.5.1 Grounding the ACU The ACU should preferably be grounded with the short ADU cable and a grounding kit (available from Thrane & Thrane). Further, the ACU must be grounded at its grounding stud in order to ensure a proper grounding if the short ADU cable is disconnected.
Page 319: Grounding The Adu
Alternative grounding for fibre glass hulls F.5.2 Grounding the ADU If the mounting base of the ADU is electrically connected to any other ground potential than the ACU (e.g. Lightning Ground), the ADU must be isolated at its mounting bolts by means of shoulder bushings and washers - see section F.6.3.
Page 320: Separate Ground Cable
Separate ground cable Separate ground cable F.6.1 Ground cable - construction When dealing with electrical installations in a marine environment, all wiring must be done with double insulated, tinned strands, high quality and if exposed also UV resistant cables. This shall also apply to the separate ground cable mentioned in the previous paragraphs.
Page 321: Ground Cable - Connection
Separate ground cable F.6.2 Ground cable - connection Mount the ground cable close to and parallel to the shielded coax cable thus minimizing ground loop problems. If possible, route the coax cable and the ground cable in metal conduits bonded to the hull or within a mast (depending on the actual installation).
