C. GENERAL INFORMATION
1. GROUND CONNECTION
This radio may be installed and used in any 12V DC negative or
positive ground system vehicle.
a) Negative ground system : Connect the Red power lead from the
radio to the positive or (+) battery terminal or other con-
venient point, and connect the Black power lead to the chassis
or vehicle frame or (-) battery terminal*
b) Positive ground system : In the cases of positive ground sys
tem, connect the Black power lead from the radio to the nega
tive or (-) battery terminal or other convenient point, and
connect the Red power lead to the chassis or vehicle frame
or (+) battery terminal.
2. ANTENNA
This radio is designed to operate into a 50 ohm CITIZENS RADIO
an terma. Best result will be obtained from your transceiver if
you use good antenna and properly install your antenna. (Refer
to the antenna installation instructions included with your an
tenna. )
A vertically polarized quarter—wavelength whip antenna provides
the most reliable operation and greater range. The shorter loa—
ded—type whip antennas are more attractive, compact and adéquate
for applications where the maximum possible distance is not re—
quired. Also, the loaded whip antennas do not present the Pro
blems of height imposed by the füll quarter-wavelength whip.
When installed in a boat, the transceiver will operate most
efficiently «dien the antenna used has been especially designed
for marine applications.
Mobile whip antennas utilize the metal body of the vehicle as a
ground plane. When mounted on a corner of the vehicle, they are
slightly directional, in the direction of the body of the vehicle.
For ail practical purposes, however, the radiation pattern is non-
directional. A slight directional characteristic will be observed
оniy at extreme distances. A standard antenna connector (Type
