Installation of Antenna System DELTA 200 S
Antenna position:
The antenna system DELTA 200 S should be mounted at the mast-head. No other antennas should
be mounted above the antenna system.
Antenna cable:
For the antenna system DELTA 200 S coaxial cable with a characteristic impedance of 50 Ohm is
used, preferably Aircell-7 or Belden H2000 Flex. A BNC-plug is used at both ends of the antenna
cable. ATTENTION! UHF-connectors (PL-connectors) may NOT be used for this antenna
system! Important: Keep the plug strain-relieved! An optional disconnecting point at the mast-heel
is established with BNC-connectors. Keep the antenna cable to the distribution box AV 205 as short as
possible. Check the antenna cable for short circuit before connecting it!
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 box AV 205:
Install the distribution box AV 205 below deck near the instruments connected.
Connect the antenna cable to the AV 205 terminal „Input: Antenna DELTA 200 S“.
Connect the VHF radio telephone to terminal 5 „UKW-Funktelefon (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.
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 DELTA 200 S 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.
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.
Installation of plug-in modules
Two plug-in modules can be inserted into the distribution box AV 205. For retrofitting of plug-in
modules, open the AV 205 case. The plug-in modules have 2 connection pins on one side and 3 pins
on the other side. Insert the plug-in module into the sockets of the AV 205 main board with the 3 pin
end of the module at the output side of the AV 205. Then close the AV 205 case and identify the
association on top of the AV 205 cover using a waterproof marker.
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.
