INSTALLATION
An extremely important requirement is the ease of installation and removal
for those occasions when you might want to remove the unit for service and
maintenance.
The most common mounting position for a transceiver is under the dashboard
directly over the drive shaft hump. Do not mount the transceiver in the path of
the heater or air conditioning.
Take your time and plan your installation carefully. When you have determi-
ned the best location for mounting, use the mounting bracket as a template to
mark mounting holes. Take care when you drill the holes that you do not drill
into wiring, trim or other accessories.
Mount in position with bolts, lock washers and nuts or self-threading screws.
Insert the power cable with lighter plug into the vehicle’s cigarette lighter cord.
Before operating, you must install and connect your antenna system. The
lead from the antenna you’ve installed should be connected to the antenna
coaxial connector. If you are using an external speaker, connect it to the EXT-
SPKR jack.
INSTALLING AN ANTENNA
A mobile antenna system is not limited to the antenna only. The transmission
line, as well as the vehicle, are important factors in the total antenna system.
Therefore, you must use the correct type of transmission line and mount the
antenna securely in a position that will give you optimal results.
Use coaxial cable with an impedance of 50 Ohms. Generally speaking, you
should keep the length of the transmission line to a minimum.
The above discussion is as important for reception as it is for the transmis-
sion. If a mismatch exists between the antenna and the receiver, the excellent
sensitivity and signal-to-noise radio of the receiver circuit will be defeated.
Useful information
1. Place the antenna as high as possible
2. The longer the antenna is, the better will be the performance
3. Mount the antenna and keep antenna cable away from noise sources,
such as the ignition switch, gauges, etc.
4. Make sure you have a solid metal-to-metal ground connection.
5. Prevent cable damage during antenna installation.
There are many types of mobile CB antennas: a full quarter-wave length
whip, a center loaded whip, top loaded whip and the base loaded type. For
a greater efciency it is recommended 2.5 m long, full quarter-wave whip.
