CONNECTION AND INSTALLATION

■ Ground connection

The transceiver and antenna tuner MUST have an
adequate RF ground connection. Otherwise, the
overall efficiency of the transceiver and antenna
tuner installation will be reduced. Electrolysis,
electrical shocks and interference from other
equipment could also occur.
For best results, use 50 or 75 mm (2 or 3 inches)
wide copper strap and make the connection as short
as possible. Ground the transceiver and antenna
tuner to one ground point, otherwise the voltage
difference (in RF level) between 2 ground points may
cause electrolysis.
RWARNING! When grounding to a metal hull

electrolysis.
Ask your technical dealer, installer or refer to a
technical book, etc., for RF grounding details.
Ground system example

■ Power source

The transceiver requires a regulated DC power of
13.8 V and at least 28 A. There are two ways to
supply power:
• Direct connection to a 12 V battery in your vehicle
through the supplied DC power cable.
• Use DC power supply to connect to an AC outlet.
