**ABOUT YOUR AIS ANTENNA SPLITTER

**

ABOUT AIS

The marine Automatic Identification System (AIS) is a location and vessel information reporting system. It allows vessels equipped with AIS to automatically and dynamically share and regularly update their position, speed, course and other information such as vessel identity with similarly equipped vessels. Position is derived from the Global Positioning System (GPS) and communication between vessels is by Very High Frequency (VHF) digital transmissions.
There are several types of AIS devices as follows:

  • Class A Transceivers. These are similar to class B transceivers but are designed to be fitted to large vessels such as cargo ships and large passenger vessels. Class A transceivers transmit at a higher VHF signal power than class B transceivers and therefore can be received by more distant vessels, and also transmit more frequently. Class A transceivers are mandatory on all vessels over 300 gross tonnes on international voyages and certain types of passenger vessels under the SOLAS mandate.
  • Class B Transceivers. Similar to class A transceivers in many ways, but are normally lower cost due to the less stringent performance requirements. Class B transceivers transmit at a lower power and at a lower reporting rate than class A transceivers.
  • AIS Base Stations. AIS base stations are used by Vessel Traffic Systems to monitor and control the transmissions of AIS transceivers.
  • Aids to Navigation (AtoN) Transceivers. AtoNs are transceivers mounted on buoys or other hazards to shipping that transmits details of their location to the surrounding vessels.
  • AIS Receivers. AIS receivers will generally receive transmissions from class A transceivers, class B transceivers, AtoNs and AIS base stations but do not transmit any information about the vessel on which they are installed.

Because VHF radios and AIS devices operate within the same frequency range and therefore require the same type of VHF antenna it is possible to utilise a single VHF antenna for both devices by using an AIS antenna splitter.
This AIS antenna splitter is designed to work primarily with AIS class B transceivers, although it will operate equally well with AIS receivers.
It is not recommended to use this AIS antenna splitter with Class A transceivers, Aids to Navigation transceivers or AIS base stations.

OPERATION

  • Operation of the AIS antenna splitter is automatic and requires no user intervention.
  • During operation the antenna splitter will share signals received at your VHF antenna with both the AIS transceiver and the VHF radio.
  • When either the AIS transceiver or VHF radio transmits, the AIS antenna splitter will automatically sense the transmission and route the signal to the antenna.
  • In the event that both the VHF radio and AIS transceiver are transmitting at the same time, the AIS antenna splitter will give priority to the VHF radio.
  • It is not possible for both connected devices to transmit simultaneously using a single VHF antenna. Whilst you are talking on your ! VHF radio no AIS position reports will be transmitted.

INDICATOR FUNCTIONS
The AIS antenna splitter includes three coloured indicators as shown in Figure 10. The state of the indicators provides information regarding the status of the AIS antenna splitter.

GME-AISS120-AIS-Antenna-Splitter-FIG-10

The indicators provide the following functions:

  • Power – this indicator is illuminated whilst the unit is powered
  • TX AIS – this indicator flashes to indicate AIS transmissions
  • TX VHF – this indicator flashes to indicate VHF radio transmissions

Note that both the TX AIS and TX VHF LEDs may illuminate when the AIS antenna splitter is used with some brands of VHF radio at the high output power (25W) setting.
This is normal behaviour and does not indicate a fault.

TROUBLESHOOTING

Issue Possible Cause and Remedy
Power indicator is not illuminated Check power supply connections and fuse or

circuit breaker

Check the polarity of power supply connections Check the power supply voltage

‘VHF’ indicator does not illuminate when the VHF Radiotelephone is transmitting| Check the antenna output of the VHF radiotelephone is connected to the antenna splitter input labelled ‘VHF’
‘AIS’ indicator does not illuminate when the AIS transceiver is transmitting| Check the antenna output of the AIS transceiver is connected to the antenna splitter input labelled ‘AIS’
Clicks or pops are heard from a connected FM broadcast receiver| This is normal and may occur during VHF or AIS transmission
VHF or AIS transmission range is reduced| A small reduction in transmission range is normal due to the insertion loss of the antenna splitter
Both the ‘AIS’ and ‘VHF’ indicators illuminate when the VHF radio is transmitting| This is normal operation with some brands of VHF radio and not a fault. The function of the antenna splitter is unaffected

If the guidance given in the table above does not rectify the problem you are experiencing please contact your dealer for further assistance.
