Installation of Antenna System ADRIA 3G AIS
The antenna system ADRIA 3G AIS consists of the antennas DELTA 163S, DELTA 3G and DELTA
150 S which are mounted together building a unity.
Antenna position:
The antenna system ADRIA 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 ADRIA 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 163S + 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:
Connect the plug on top of the DELTA 3G to the DELTA 163S 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 may be connected to
the negative element of the power supply via the cellular telephone or VHF.
Installation of the distribution box AV 303 and the AIS-Receiver:
Install the distribution box AV 303 below deck near the instruments connected. All connectors of the
AV 303 are of BNC type. 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. 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“. Connect AV 303 terminal „VHF“ to the VHF radio.
Directly connect the AIS-Receiver to the DELTA 150 S cable.
Power supply:
For the antenna system ADRIA 3G AIS no power supply is needed.
To guarantee a perfect working antenna it is mandatory to do the installation in a workman-like
manner.
Any faults caused from neglecting these instructions are excluded from the manufacturer's
warranty.
In case of doubt consult a specialist.
