2. Onvesselsthatcannotfullrequirementsinitem1,theantennamustbemountedsothatitslowestpointis
at least 6 ft. (1.8m) vertically above the heads of people on deck and all persons must be outside the 6 ft. (1.8
m) MPE radius during radio transmission.
• Always mount the antenna at least 6 ft (1.8 m) from possible human access.
• Never touch the antenna when transmitting
• Use only authorized T&T accessories.
3. If the antenna has to be placed in public areas or near people with no awareness of the radio transmission, the
antenna must be placed at a distance not less than 12 ft. (3.6 m) from possible human access.
Failure to observe any of these warnings may cause you or other people to exceed FCC RF exposure limits or create
other dangerous conditions.

1.1 Introduction
The 150 W/250 W/500 W MF/HF transceiver with integrated DSC and telex is designed for maritime
applications in voluntary as well as compulsorily tted vessels. It offers simplex and semi-duplex SSB
radiotelephone communication in the maritime mobile frequency bands between 1.6 and 30 MHz. The
basic version of the transceiver includes voice, DSC and a dedicated 2187.5 KHz DSC watch receiver,
forming an ideal system for MF GMDSS installations.
The equipment consists of a compact transceiver control unit, a fully remote controlled transceiver unit
and an automatic antenna tuning unit.
The microprocessor controlled Antenna Tuning Unit automatically matches the impedance of antennas
between 8 and 18 metres in length and requires no presetting at the installation. The typical tuning time is
1 s. It is designed for outdoor installation and may be located up to 100 metres from the Transceiver Unit.
The Transceiver Unit contains all receiver and transmitter circuits. The fully protected solid state 150 W/
250 W /500 Wpower amplier cooled by natural convection matches a 50 ohm antenna system, but
is normally used in connection with the Antenna Tuning Unit. The DSC/Telex modem contains two
demodulators, one connected to the built-in watch receiver for continuous watch on the DSC distress
frequency 2187.5 KHz, the other connected to the communication receiver which may be used to keep
simultaneous watch on other DSC frequencies or may be used for telex communication.
The transceiver can easily be upgraded to include 6 channel scanning DSC watch receiver, and Telex
operation to comply with MF/HF requirements in sea area A3. The upgrade is done by entering software
license codes.
The Control Unit is for operation of radiotelephone as well as DSC and telex functions. Use of the equipment is simple, logic and straight forward. DSC operation is based on the use of soft keys. Guiding texts
are provided and the large display is able to show the contents of a complete call in one screen.
For telex operation the Message Terminal is connected to the system through the CAN bus.
The equipment is designed for operation from a 24 V battery. With the optional AC Power Supply unit
installed the equipment may be supplied from 115/230 V AC main or emergency supplies with automatic
switch-over to 24 V DC supply in the absence of AC supply voltage. Also optionally, a battery charger for
AC is available in the product line.
The built-in test facilities and easy-to-replace module design of the equipment simplies the service concept.

2.3 Ground connections
2.3.1 Antenna Tuning Unit
As the earth connection of a transmitter is a very
important part of the antenna system, it is of the
utmost importance to keep in mind that the earth
connection of the Antenna Tuning Unit must
have the lowest possible RF-impedance. Losses in
the earth connection will result in a decrease in
radiated power which means that the range of the
transmitter will be reduced. In steel ships a 100 x
0.5 mm copper strap as short as possible is connected between the earth terminal at the bottom
of the Antenna Tuning Unit and two or three 1/2"
or M12 bolts welded to the superstructure. Vessels
constructed of non-conducting materials must be
equipped with a copper earth plate having a minimum area of 1 square metre mounted below the
water line. From a copper earth bolt hard soldered
to the earth plate a 100 x 0.5 mm copper strap is
run, preferably uninterrupted to the earth terminal
at the bottom of the Antenna Tuning Unit.
Should it be necessary to break the copper strap, for example to pass through a deck, two or three 1/2"
or M12 bolts should be used for this feed through. On wooden ships having a superstructure of metal,
this superstructure should also be effectively connected to the copper strap by using stainless steel bolts
and preferably pieces of stainless steel strips between the metal parts. On bre glass boats, such as yachts
and sailing boats, it may be difcult to install a sufciently good earth. Short copper straps are bolted
to conducting parts on the engine, the keel and other conducting objects. Many copper straps can be
glued to the inner surface of the hull below the water line to produce a large capacitance to the water.
It is important that the total area of copper is large and that the distance between the copper surface
and the water is as small as possible. The copper straps are connected directly to the ATU.
On ships where the environmental conditions require shielded grounding downlead in order to avoid
radiation from same downlead, it is recommended to use a shielded cable with a non-stranded wire
having adequate wire dimension to securee the proper grounding. Cable shielding should be connected
at ATU mounting kit and left open at the earth connection side.
2.3.2 Transceiver Unit and Control Unit
The Transceiver Unit is preferably grounded
separately to the ships metal in the shortest
possible way. A 10 to 16mm sq. ground wire
is connected to the ground terminal (cable
clamp) at the bottom of the unit.
