Basic equipment for CB Radio is combine of a Radio (or Rig) it shelf, Power Supply Unit (PSU), Antenna and coaxial or twin lead cable.
Basic CB Radio:
Have one Band and 40 channel's, of AM (amplitude modulation) and FM (frequent modulation) modulation, and have a 1W (Wat) of output power on AM modulation and 4W on FM modulation. But this variate form country to country and theirs law (eg. in some countries you can legally only have 40 FM channels and and 12 AM from 4th to15th channel). And run on 12-13,8 volts and the amount of current hay need witch depends on the radio ti shelf, its output power, modifications and more...
Power Supply Unit:
Depends of your CB transceiver current consumption, for basic AM FM transceiversh with maximum 4W output power you while need a 12-13,8 volts, 4A (amps) DC regulated power supply or bather. But most Radios CB ore HAM runs on 12-13,8 volts and need all kind of current from 1A or 2A all the way to 5A, 10A or 20A depends (of output power, modifications, accessories and rig it shelf). So basically you can put one in your car and run it on the 12V battery or take it in the house and run it trough a 12-13,8V PSU.
The power supply on the picture below have 13.5v of 10A, but do not get distracted if your radio need 4A he while take only 4A from PSU, not all 10A so the radio while not get fried. And the lack of 0,3v while not make differences because the radios are working in the range of 12V to 13,8V as I say before.
Just be sure to match the colors of the Radio power cables with the color of the PSU output knobs bee sure that + (red) or -(black) are not mixed because that can fry the radio.
The Antenna:
First the frequency of CB Radio is 27Mhz or 11m wave length. There is all kind of size, shapes and types of antennas. Size variate from 1/4 to 5/8 and full wave length of 11m. Types are mobile(on cars and trucks), vertical, horizontal (or dipole), and yagi (pointed vertical or horizontal or bout).

Mobile Antennas
Are use on Truck, Automobile, Motorcycles, Bicycles and pretty much on everything that moves. As you can see they comes in every shapes and sizes.
Vertical Antennas
Vertical antenna also comes in all shapes and sizes, but the most popular are 5/8 GP (Ground Plane or antenna with radials) or single rod. 5/8 means that you have antenna that is 5/8 of a wave length (11m or 36.0892 foot). On the image below you can see Vertical Rod and GP or Ground Plane antennas, the closer one is a GP Antenna and their are bout 5/8 of wave length. GP antenna can have 3 or 4 radials.
The good old dipole can be a simple wire or aluminum tube and of course it can be vertical ore horizontal mounted. And it is the simplest antenna for homemade production fore the beginners, but it can also and not to often use by lets call them pro CB'ers.
Horizontal Dipole |
Vertical Dipole |
The Yagi Beam Antennas work and have same principles as the others antennas bud do to the element allows you to point your antenna at the specified part of the lets say world.
3 element horizontal yagi |
Left element vertical and Right 6 element horizontal and vertical yagi |
