INSTAllATION
MOBILE STATION INSTALLATION
Plan the location of the transceiver and microphone bracket before starting the
installation. Select a location that is convenient for operation and does not interfere
with the driver or passenger in the vehicle. The radio should be securely fastened to
some solid face, using the mounting bracket and self-tapping screws which are
provided.
MOBILE STATION ANTENNA
Since the maximum allowable power output of the transmitter is limited by the
F.C.C., the antenna is a very important factor affecting transmission distance. It is
for this reason that we strongly recommend that you install only a quality antenna in
your new citizens band system. You have just purchased a superior transceiver. Don't
diminish its performance by installing an inferior antenna.
Only a properly matched antenna system will allow maximum power transfer from
the 50-ohm transmission line to the radiating element. Your UNIDEN dealer is
qualified to assist you in the selection of the proper antenna to meet your applica-
tion requirements.
For automobile installation, the whip antenna may be used with good effect. The
most efficient and practical installation is a full quarter wave whip antenna mounted
on the rear deck or fender top midway between the rear window and bumper.
A short "loaded" whip antenna is more convenient to install on you automobile,
although the efficiency is less than a full quarter wave whip antenna.
For marine installation, consult your dealer for information regarding an adequate
grounding system and prevention of electrolysis between fittings the hull and water.
GROUND INFRMATION
Most newer U.S. and foreign made cars and small trucks use a negative ground
system, while some older cars and some newer large trucks may use a positive ground
system.
A negative ground system is generally identified by the (-) battery terminal being
connected to the vehicle motor block, but if you cannot determine the polarity
system of your vehicle, it is suggested that you consult your vehicle dealer for
definite information.
POWER CORD CONNECTION: NEGATIVE GROUND SYSTEM
If you are operating on a negative ground system, connect the red DC power cord
from the transceiver to the positive, or (+), battery terminal or other convenient
point and connect the black power lead to the chassis or vehicle frame, or (-) battery
terminal.
