Plan the location of the transceiver and microphone bracket before starting the
installation. Select a location that is convenient for operation and does not interfère
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.

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. Y ou hâve 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 U N I D E N dealer is
qualified to assist you in the sélection 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 füll 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 füll quarter wave whip antenna.
For marine installation, consult your dealer for information regarding an adéquate
grounding system and prévention of electrolysis between fittings the hüll and water.

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 détermine the polarity
system of your vehicle, it is suggested that you consult your vehicle dealer for
definite information.

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.
