Antenna Coupler AT-1575, AT-5075

The Antenna Coupler is installed between the antenna and the Transceiver Unit, and
tunes the antenna to the transmitter. The coupler must have a correct ground to func-
tion properly. The radiotelephone cannot provide its intended performance unless the
ground is proper.
1.2.1 Installation location
The water-jetsproof construction of the antenna coupler permits installation either in-
doors or outdoors. Install the unit on a bulkhead or the overhead (indoor installation).
Do not install the unit on a deck.
When selecting a location, keep in mind the following points.

General considerations

• Follow the compass safe distances listed in the Safety Instructions to prevent inter-
ference to a magnetic compass.
• Leave enough space around the sides of the coupler for maintenance and checking.
See the outline drawing for minimum space.
• See section 1.2.2 to ground the equipment.

Indoor installation

• Install the unit away from GNNS equipment, radio equipment, etc. to prevent mutual
interference.
• The lead-in wire should be as near to the coupler as possible.
DANGER
ELECTRICAL SHOCK HAZARD
Do not touch lead-in wire or
insulator. Electric shock, fire,
serious injury or death can
result if the cables or insulator
are touched while the
radiotelephone is transmitting.
