Installation of Antenna System HAWAII 3G AIS
The antenna system HAWAII 3G AIS consists of the antennas DELTA 200 S, DELTA 3G and
DELTA 150 S, which are mounted together building a unity.
Antenna position:
The antenna system HAWAII 3G AIS should be mounted at the mast-head. No other antennas should
be mounted above the antenna system.
Antenna cable:
For the antenna system HAWAII 3G AIS coaxial cables with a characteristic impedance of 50 Ohm are
used, preferably Aircell-7 or Belden H2000 Flex. An N-plug is used to connect the DELTA 150 S, and
a BNC-plug is used to connect the DELTA 200 S + DELTA 3G. ATTENTION! UHF-connectors
(PL-connectors) may NOT be used for this antenna system! Important: Keep the plug strain-
relieved! Optional disconnecting points at the mast-heel are established with BNC- and N- connectors
to avoid mix-up. Keep the antenna cable to the distribution box AV 303 as short as possible. Check
the antenna cables for short circuit before connecting them!
Assembling the antennas:
First connect the plug on top of the DELTA 3G to the DELTA 200 S and put together these two
antennas. Then pull the antenna cable with BNC-plug through the tube of the antenna holder AH 12
and through the hole of the DELTA 150 S, and connect it to the DELTA 3G. Pull the antenna cable
with N-plug through the hole of the antenna holder AH 12 and connect it to the DELTA 150 S; Finally
put together the antennas and screw them to the antenna holder.
Important: All metal parts of the antennas as well as the connectors must not have electrical
contact to other metal parts of the ship because the shield of the cable is connected to the
negative element of the power supply.
Installation of the distribution boxes AV 205 and AV 303:
Install the distribution boxes AV 205 and AV 303 below deck near the instruments connected.
Mount the distribution box AV 303 in a way that the connectors are on the left side. Then the terminal
„Mobile Telephone“ is at the upper position, the terminal „DELTA 3G“ is in the middle and the terminal
„AV 205 Input 6“ is in the lower position.
All connectors of the AV 303 are of BNC type. Connect the Mobile Telephone to the AV 303 terminal
„Mobile Telephone“using a short cable. Connect the antenna cable to the AV 303 terminal
„DELTA 3G“. Use a BNC-BNC cable to connect AV 303 terminal „AV 205 Input 6“ to AV 205 terminal
„Input: Antenna DELTA 200 S“. Connect the VHF radio telephone to terminal 5 „Output (VHF) “. This
is the only terminal with UHF-connector to avoid confusion. Connect the remaining instruments to
terminal 1 to 4 of the AV 205 using BNC-connectors (see AV 205-cover for association).
Directly connect the AIS receiver to the DELTA 150 S cable.
None of the instruments connected to this system may be connected to ground.
Power supply:
Important: Do not switch on the power supply before the installation is completed!
Use a switch or cutout of the switch board for the power supply to switch off the antenna system when
none of the receivers connected is in use. Connect the blue lead of the AV 205 power supply cord to
the negative element and the brown lead to the positive element of a 12V or 24V power supply. The
yellow/green lead of the AV 205 power supply cord has to be connected to a good ground.
For the operation of the antenna system HAWAII 3G AIS it is important that the distribution box
AV 205 is connected to the power supply before (or as soon as) the receiver instruments connected to
the AV 205 are switched on; else faulty operation may occur (antenna alarm, incorrect calculation of
position, etc.). The power supply to the antenna system need not be switched on for the
operation of the VHF marine telephone, the AIS Receiver controller or the Mobile Telephone.
Not all receivers are able to handle the antenna voltage from the DELTA 200S without producing
interference. Therefore the output level of the corresponding wideband output can be reduced by
adjusting the associated trimmer potentiometer counter-clockwise until the reception is clear again.
