Installation of Antenna System PACIFIC 4G
The antenna system PACIFIC 4G consists of the antennas DELTA 200 S, DELTA 4G and DELTA 12 M,
which are mounted together building a unity.
Antenna position:
The antenna system PACIFIC 4G should be mounted at the mast-head. No other antennas should be
mounted above the antenna system.
Antenna cable:
For the antenna system PACIFIC 4G 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 12 M, and a BNC-plug is
used to connect the DELTA 200 S + DELTA 4G.
ATTENTION! UHF
- connectors (PL
- connectors) may
NOT be used for this antenna system!
Important: Keep the plugs strain-relieved!
Optional
disconnecting points at the mast-heel are established with BNC- and N- connectors to avoid mix-up. Keep
the antenna cables to the distribution boxes AV 112 and AV 304 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 4G 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 12 M, and connect it to the DELTA 4G. Pull the antenna cable with N-plug through the
hole of the antenna holder AH 12 and connect it to the DELTA 12 M. 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.
Install the distribution boxes AV 112, AV 205 and AV 304 below deck near the instruments connected.
Installation of the distribution boxes AV
205 and AV 304:
Mount the distribution box AV 304 in a way that the connectors are on the
left
side. Then the terminal
„GSM/UMTS/LTE“ is at the upper position, the terminal „DELTA 4G“ is in the middle and the terminal
„AV 205 Input 6“ is in the lower position.
Connect the mobile telephone or GSM/UMTS/LTE router or GSM/UMTS/LTE modem to the AV 304 terminal
„GSM/UMTS/LTE“ using a short cable.
Connect the antenna cable to the AV 304 terminal „DELTA 4G“.
Use a BNC-BNC cable to connect AV 304 terminal „AV 205 Input 6“ to AV 205 terminal
„Input: Antenna DELTA 200 S“.
Connect the VHF/DSC 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).
None of the instruments connected to this system
may be connected to ground.
Installation of the AV 112:
Install the distribution box AV 112 below deck near the instruments connected. Open the
AV 112 box to mount it. For that purpose pull off the cover by carefully drawing the corners
alternately. Fix the AV 112 box using 2 screws of about 3 mm diameter (see overleaf).
Thereafter press the cover to the bottom part until it snaps in.
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. Use a switch or cutout of the switch
board for the power supply to switch off the AV 112 if no radio or TV is to be received.
Connect the power supply connector to the ship’s power supply of 12 V or 24 V using a cable
of 2 × 0.5 to 1.5 mm² (positive wire next to the fuse; negative wire next to the LED - see
overleaf).
Connect the blue lead of the AV 205 und the AV 112 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.
