Antenna Installation; Power Connection - PRESIDENT MC KINLEY USA 12/24 V Manual Del Usuario

2) ANTENNA INSTALLATION

a) Choosing your antenna
- For CB radios, the longer the antenna, the better its results.
Your dealer will be able to help you with your choice of
antenna.
b) Mobile antenna
- Must be fixed to the vehicle where there is a maximum of
metallic surface (ground plane), away from windscreen
mountings.
- If you already have a radio-telephone antenna installed,
the CB antenna should be higher than this.
- There are two types of antenna: pre-regulated which
should be used on a good ground plane (e.g. car roof or
lid of the boot), and adjustable which offer a much larger
range and can be used on a smaller ground plane (see §
ADJUSTMENT OF SWR page 7).
- For an antenna which must be fixed by drilling, you will need
a good contact between the antenna and the ground
plane. To obtain this, you should lightly scratch the surface
where the screw and tightening star are to be placed.
- Be careful not to pinch or flatten the coaxial cable (as this
runs the risk of break down and/or short-circuiting).
- Connect the antenna (B).

c) Fixed antenna
- A fixed antenna should be installed in a clear space as
possible. If it is fixed to a mast, it will perhaps be necessary
to stay it, according to the laws in force (you should seek
professional advice). All PRESIDENT antennas and acces-
sories are designed to give maximum efficiency to each
CB radio within the range.

3) POWER CONNECTION

Your PRESIDENT MC KINLEY USA 12/24 V is protected against
an inversion of polarities. However, before switching it on, you
are advised to check all the connections. Your equipment
must be supplied with a continued current of 12 or 24 volts
(A). Today, most cars and lorries are negative earth. You
can check this by making sure that the negative terminal
of the battery is connected either to the engine block or
to the chassis. If this is not the case, you should consult your
dealer.
a) Check that the battery is of 12 or 24 volts.
b) Locate the positive and negative terminals of the battery
(+ is red and - is black). Should it be necessary to lengthen
the power cable, you should use the same or a superior
type of cable.
c) It is necessary to connect your CB to a permanent (+) and
(-). We advise you to connect the power cable directly to
the battery (as the connection of the CB cable to the wiring
of the car-radio or other parts of the electrical circuit may,
in some cases, increase the likelihood of interference).
d) Connect the red wire (+)
to the positive terminal of
the battery and the black
(-) wire to the negative
terminal of the battery.
e) Connect the power ca-
ble to your CB radio.
