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, electri-
cal 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 dif-
ference (at the RF level) between 2 ground points
may cause electrolysis.
RWARNING! When grounding to a metal hull
Use Zinc anodes to protect the hull from electroly-
sis.
Ask your technical dealer, installer or refer to a
technical book, and so on, for RF grounding de-
tails.
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 sup-
ply power:
• Direct connection to a 12 V battery in your vehicle
through the supplied DC power cable.
• Use a DC power supply connected to an AC outlet.
