1.1 Safety warnings

1.2 General notices

Compass safe distance

The compass safe distance of this unit is 0.5m or greater for 0.3° deviation.

RF emissions notice

The information provided in this section assumes the AIS antenna splitter is connected to an AIS Class B transceiver.

The warnings regarding RF emissions provided in the manual forthe VHF radio being used with the AIS antenna splitter should also be

noted prior to installation of the AIS antenna splitter.

Caution: The AIS antenna splitter generates and radiates radio frequency electromagnetic energy. This equipment must be installed

and operated according to the instructions contained in this manual. Failure to do so can result in personal injury and/or the malfunction

of the AIS antenna splitter and/or the AIS transceiver it is connected to.

Caution: Never operate the AIS antenna splitter unless it is connected to a VHF antenna.

To maximise performance and minimise human exposure to radio frequency electromagnetic energy you must make sure that the

antenna is mounted at least 1.5 meters away from the AIS antenna splitter and is connected to the AIS antenna splitter before power

is applied.

The system has a Maximum Permissible Exposure (MPE) radius of 1.5m. This has been determined assuming the maximum power of the

AIS transceiver and using antennas with a maximum gain of 3dBi.

When reading this manual please pay particular attention to warnings marked with the warning triangle shown on the

left. These are important messages for safety, installation and usage of the product.

This equipment must be installed in accordance with the instructions provided in this manual.

Only use this AIS antenna splitter in conjunction with an approved AIS transceiver or receiver purchased from a

reputable supplier.

Do not install this equipment in a flammable atmosphere such as in an engine room or near to fuel tanks.

Notices

The antenna should be mounted 3.5m above the deck in order to meet RF exposure requirements. Higher gain antennas will require a

greater MPE radius. Do not operate the unit when anyone is within the MPE radius of the antenna (unless they are shielded from the

antenna field by a grounded metallic barrier). The antenna should not be co-located or operated in conjunction with any other

transmitting antenna. The required antenna impedance is 50 ohms.

2.1 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 a number of types of AIS device 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 which transmit

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.
