Installation Manual PLANNING


Placing the Antenna

Radome type Nera F77 is delivered either with mast mounted or deckmounted radome. See previous page.

The mast mounted version includes a hatch which providesaccess for service and repair, whereas the deck mountedversion must be lifted down.

Avoiding obstructions The antenna has a beamwidth of 7.5 degrees (at 3 dB points)and ideally requires a free line of sight in all directions above anelevation angle of +5 degrees.Any obstruction will cause blind sectors, resulting in signaldegradation or even loss of communication with the satellite.

Degradation of the satellite signal can only be completelyavoided by placing the antenna higher than any obstructions.This is often not feasible and a compromise must be made toreduce the number of blind sectors and cost of installation.

The degree of signal degradation depends on the size of theobstructions; the distance to them must therefore be consid-ered.

Preferably, all obstructions within 3 m of the antenna should beavoided. Obstructions less than 15 cm in diameter can beignored beyond this distance.

Radiation precautions Passengers should not be admitted in areas closer than 5 mfrom the antenna.

However, no restrictions are required when the antenna radomeis installed at least 2 m above the highest point accessible topassengers.

Personnel should not be close to the antenna for periods ofmore than 1 hour per day without switching off the RF transmit-ter.


7/54

PLANNING


Avoiding interference Do not locate the antenna close to interfering signal sources, orin such a position that the source (e.g. radar-antenna) radiatesdirectly into the Saturn antenna.

The Above Deck Equipment (ADE) should be separated as faras possible from other transmitters, and preferably by at least5 m from the antenna of other communication or navigationequipment, such as the antenna of the satellite navigator, theVHF antenna or radar equipment.

Compass safe distance For installation on British or Norwegian vessels, the antennashould be located at a distance of at least 1.0 metres from themagnetic steering compass. Be aware that requirements mayvary from one country to another.

Other precautions Do not place the antenna close to the funnel, as smoke depos-its will then eventually degrade antenna performance.

The antenna should be installed so that severe vibration andshock are avoided.If installed on top of a signal and radar mast, the mast must be

supported by stays.


8/54

Antenna Unit Mounted on Mast

Designing the Antenna mast

The mast must be designed to carry the weight of the antennaunit, approximately 65 kgs. It must be able to withstand windforces of up to 120 knots on the radome as well as the onboardvibration levels. The radome is 1.080 m high and has a maxi-mum diameter of 1.312 m.

The top end of the mast should be fitted with a flange with holesmatching the bolts extending from the bottom of the radome.See figure below.The flange must not be so large as to inter-fere with the hatch at the bottom of the antenna unit. The holesthrough the mast flange must be positioned symmetricallyabout the ships longitudinal axis.

NOTE: On ships with excessive vibration the mast must besupported by stays or other adequate means.

If the height of the mast makes it necessary to climb up to theantenna unit, a ladder must be provided on the mast column. Aguard rail must be attached to the upper section for safetypurposes. If the height of the mast exceeds approximately 4.5metres, an access platform should be attached to the mastapproximately 1 metre below the radome bottom.

Be aware that requirements may vary from one country toanother.

Placing the Main Communication Unit (MCU)

The Main Communication Unit should be placed in a ventilatedarea. To ensure adequate cooling of the MCU a 10 cm unob-structed space must be maintained above and below the unit.

A space of 10 cm above theMCU is also required toallow removal of units.

For grounding, see"Grounding considera-tions" and "Location andgrounding of units".

Ambient temperature range0O - 45OC.

The MCU is manufactured as

a cabinet for wall or desktopinstallation with dimensionsas shown. Six holes throughthe MCU mounting plateallows the unit to be securedto the wall or desk top.

Placing the Distress Alarm Unit & ISDN Handset

The Distress Alarm Unit is operated inconjunction with an ISDN Handset.

The ISDN Handset functions as a displayand communication unit for alert trans-mission. It may also be used for normalvoice communication.

Up to two (2) Distress Alarm Units &ISDN Handsets may be connected inseries. The units may be installed any-where onboard the vessel.

Four separate ISDN ports are available

on the MCU as RJ45 jacks or screwterminal blocks.

Grounding considerations

A successful installation of a maritime satellite terminal must takeinto account the noisy environment in which the equipment shalloperate.

Electrical noise The electrical environment on board a ship is usually quite noisy.Powerful electrical installations cause voltage variations andtransients, as well as low and high frequency noise. Radio andradar equipment radiate radio frequency signals which frequentlyimpregnate cables on board with unwanted interference.

Ground plane Most ships have a steel hull. One should think that the steelconstruction of the ship would constitute a good ground plane.This is often not quite true. Rust, other forms of corrosion, paintand grease, often prevent a good ground connection. A conse-quence of this is that high energy power distribution on board aship can cause significant ground potential differences.

Antenna unit Adequate grounding of the Antenna Unit depends on thefastening bolts making good contact with the top flange ofthe mast. This is obtained by removing paint and usingenclosed toothed washers and nuts.

Antenna cable The antenna coaxial cable normally has a solid or meshed metalscreen which must be terminated to ground both at the antennapedestal and at the MCU. The length of the cable can often bemore than 40 metres. If the ground potential level at the twopoints differ, the current passing through the screen of the co-axial cable can be quite strong. The antenna cable screen consti-

tutes a heavy gauge wire, which is capable of conducting largeamounts of current.

Below Deck Equipment The MCU must be provided with a good electrical connection tothe ships hull for grounding. This is obtained by using copperfoil. (See Installation: "Location and grounding of units".)Length of copper foil/10 cm should not exceed 300 cm. The foilshould be connected to ship's hull (deck or roof) by hard-solder-ing (or screws) to steel.

Mains power/ground Mains ground is secured to the common grounding point throughthe external supply. It is therefore important to use the samemains branch for additional equipment connected to the MCU

(Fax, PC w/printer etc.).

PLANNING


Laying cables

General The coaxial cable for connection between the MCU and theAntenna Unit should, if possible, be laid before the equipmentarrives. Make sure sufficient length of cable is ordered.

Where exposed to mechanical wear (on deck, through bulk-heads etc.), the cable should be protected by steel pipes.Standard procedures should otherwise be followed for cablingin ship installations.

Special attention to existing safety regulations is required if thecable passes through zones where there may be flammable orexplosive gases. Use suitable gasproof cable glands or bush-ings. Be aware that the cables listed in the table below are notflame retardent.

Double screen 50 ohm coaxial cable must be used. The maxi-

mum length of the coaxial cable is limited by the DC and RFloss through the cables (including pigtails):

Maximum DC loss: R loop 2.0 ohm

Maximum RF attenuation at 1.6 GHz: < 23 dB

The table below lists suitable double screened coaxial cables between MCU and ADE:

At the Antenna Unit A free end of approximately 1.5 m of the antenna cable abovethe radome bottom should be provided for connection to thecoaxial connector in accordance with the installation instructionsin "BDE - Connecting the coaxial cable to the MCU".

At the Main The coaxial cable from the Antenna Unit should be given aCommunication Unit free end of approximately 0.5 m at the MCU location.

Nera ISDN Telephone, Choose the position for the required wall sockets and layDistress Alarm Unit, the cables leaving a free end of 0.5 m. Also allow a free end oftelefax or analogue 0.5 m at the Termination Box.telephone
