The CB Story
1 The Citizens Band lies between the shortwave broadcast and 10-meter
Amateur radio bands, and was established by law in 1949. The Class D
two-way communications service was opened in 1959. (CB also in-
cludes a Class Acitizens band and Class C remote control frequencies.)
FCC regulations permit only ÒtransmissionsÓ (one party to another)
rather than ÒbroadcastsÓ (to a wide audience). Thus, advertising is not
allowed on CB channels because this is Òbroadcasting.Ó

Installation
Location
Plan the location of the transceiver and microphone bracket before start-
ing the installation. Select a location that is convenient for operation and
does not interfere with the driver or passengers in the vehicle. In auto-
mobiles, the transceiver is usually mounted to the underneath of the
dash panel, with the microphone bracket beside it.
Mounting Connection
The transceiver is held in the universal mounting bracket by two thumb
screws, permitting adjustment at the most...

Installation (Cont.)
3.Connect the antenna cable plug to the standard receptacle on the
unit. Most CB antennas are terminated with a type PL-259 plug
which mates with the receptacle marked ÒANT.Ó
4.Connect the red lead of DC power cord to +13.8VDC. In automo-
bile installations, +13.8VDC is usually obtained from the accessory
contact in the fuse box. This prevents the set being left on acciden-
tally and also permits operating the unit without the vehicleÕs
engine running.

CB Antenna
Since the maximum allowable power output of the transmitter is limit-
ed by the FCC, the antenna is one important factor affecting transmis-
sion distance. Only a properly matched antenna system will allow max-
imum power transfer from the 50-ohm transmission line to the radiat-
ing element. In mobile installations (cars, trucks, boats, etc.), an anten-
na system that is non-directional should be used.
Avertically polarized, quarter-wavelength whip antenna provides the...
