Ham has frequencies across many bands ranging from meters thru gigahertz bands. The usage is different as well.
Hams use amateur radio to communicate over long distances and listen to emergency communications. They each have their distinct characteristics, so the best option for you will depend on your needs as a radio enthusiast.

The range of CB communication using the maximum legal power of 4 watts output varies from quite a short distance in rough terrain where hills obstruct the signal path, up to about 20 miles where antenna locations and the nature of the countryside give a path approaching "line of sight". In many rural areas, CB provides a much-needed radio "party line" for folks who have no telephones.
CB can also be a great aid to any small business which makes deliveries and pickups or is involved in other activities away from its home base. As long as there's someone back at the ranch, those who are out of the office can check periodically to learn of additional calls to be made, etc. If you travel a lot, CB can be a boon to you too.
The channel 9 emergency frequency really works for summoning aid in the event of vehicle trouble. Finally, CB walkie-talkies permit communication between hikers, climbers, boaters, and cyclists, or with kids at play or on the way to the school bus. The major considerations in selecting CB equipment are: [1] basic type of unit mobile, base station, or walkie-talkie , [2] power source volt storage battery, AC, or dry cells , [3] rated transmitter power, and [4] number of channels the unit is capable of covering.
Most mobile units and base stations available these days put out between 2. I wouldn't buy one rated at less power than this except, possibly, if I were purchasing a walkie-talkie. Considering such a device's size, weight, and battery life, one with a rating of only a watt or two might make sense. Hundred-milliwatt instruments, however, are ridiculous. They have a very short range and are more toy than tool. If you travel often, it may be worth paying the price for a CB unit with a full channel capacity.
For a rural party-line situation, as few as three channels should be adequate. Select your particular three after checking with local CBers about the area's usage patterns.
The obvious choice for a mobile installation is one of the many compact citizens' band units which run off volt DC. Another possibility is a higher-powered walkie-talkie with an adapter cord which permits the instrument to be powered by the car's battery and connected to a whip antenna mounted on the vehicle. Currently available base stations seem overpriced to me.
A less expensive alternative — a mobile unit powered by a volt storage battery and "trickle charger" — would work just as well and would continue to provide communication if the AC power failed.
CB antennas come in a wide variety of designs and sizes. Still, there's no need to over—complicate your original choice of equipment in this area. A full-length inch whip will transmit a stronger signal in mobile use than one of the shortened "loaded" whips. George notes that antenna problems can cause transistor failure in a transmitter, and suggests that a CBer purchase a low-cost VSWR indicator 'to make sure his antenna and feedline are OK.
One aspect of CB — its lawless side — stirs up a fair amount of argument. To some, illegal operation is a terrible shame. George — a homesteader who puts both amateur and CB radio to good use — suspects that "people like to be a little illegal. Perhaps, in our over-controlled society, some folks take this way to strike out at Big Daddy.
Overall, there are a lot of benefits to getting a good CB radio. There are a number of differences between these two types of radio. If you're in the market for a radio, we suggest you read on and then make an informed decision. A major difference between ham and CB is the watt at which they transmit signals. You will be able to tell how far you are from the opertor on the other side, by observing this difference. Ham radio has a power range of watts. This means you'll be able to talk and send messages to all corners of the world.
You could be sitting in front of your ham radio in your basement and send messages to the polar bears in Antarctica. Although ham radios are allowed power levels of watts by the FCC Federal Communication Commission , you'll see most enthusiasts and hobbyists with ham radios that have the power of only 50 watts.
Nonetheless, ham radio is powerful and can be used to communicate in longer distances because of its power range. So, with CB, you'll only be able to transmit within a few miles. Because of its short range, it is mostly used by truckers to get information on regional traffic, route closures, weather conditions, and local entertainment.
Because of its powerful capabilities, owning a ham radio will require you to pass an examination by the government and get a license. Ham radio is also ironically known as amateur radio even though the people who are allowed to use it, are somewhat experts. It is known as amateur radio because those who are using it are merely just enthusiasts and have learned the technicalities of radio out of sheer personal interest with no intention of gaining anything financially.
CB used to require a license , but it doesn't anymore unless you plan on running a radio station. You just have to make sure not to cross the upper limit on power. If you do take that risk, prepare to pay heavy fines to the FCC. Ham antennas are only required to be The antenna of CB radios needs to be at least 8. Ham radios enjoy the perks of having a wider range of frequency bands, which will allow you to access many channels on your radio.
It also means that ham radios can be used for TV, microwave, satellite communication, even high speed data access. The frequency band of CB radio is limited to 27MHz, so it can only be used for mostly voice transmissions.
