This article aims to explain the difference between cb and ham radio. Therefore, if you have any questions regarding two-way communication radios, we have all the answers you need.
Despite the many opportunities that technology offers when it comes to phone calls and messaging, the convenience associated with using two-way communication radios is still intact.
Just like in the past, the use of amateur and CB radios is still popular. They’re used by campers, people on road trips, and adventure fanatics. These radios’ popularity depends on how they work.
Amateur and CB radios don’t require cellular network to work. It implies that if there’s no cellular network, then using your mobile phone as a communication device is impossible. In such a situation, amateur and CB radios come in handy.
If you work within the set range for the two-way radio, and without disruptions or impedances, then you can communicate with a group of associates, friends, and members of your family for free and as long as you want.
Therefore, when it comes to comparing CB and amateur radios; yes, both are two-way radios, but, their operation is different. The wattage, range, and frequencies are diverse. Read on to get a more exhaustive explanation of these two-way radios.
What’s a CB Radio?
CB (Citizens Band) radio is used in numerous countries. It’s a land mobile radio system that allows short-distance individual-to-individual two-directional voice communication. It uses two-way radios that operate on 40 frequencies near 27 MHz in the shortwave (high frequency) band.
The CB radio is different from other personal radio services such as GMRS, UHF CB, FRS, MURS, and the Ham Radio Service. Operating CB doesn’t need a license, and dissimilar to ham radios, it can be used for business or personal communication.
Just like numerous other land mobile radio services, many radios in one locality share one frequency channel. However, only one can broadcast at a time. Usually, the radio is in receiving mode to get other radio broadcasts on the channel. If you want to talk, press the “press to talk” button on your radio. This switches on your transmitter.
If you’re on the same frequency, you have to take turns talking. The range of CB radios is around 4.8 km (3 miles) to 32 km (20 miles) based on the terrain, for a line of sight communication. However, a variety of radio propagation conditions can allow you to communicate over longer distances.
What’s a Ham Radio?
It’s also known as amateur radio. This is using radio frequency specter for non-commercial communication, personal recreation, wireless experimentation, self-training, contending, radiosport, and even communicating in an emergency.
The term “amateur” portrays one who is permitted or is interested in the radioelectric practice. However, it should only have an individual aim and no financial rewards (either direct or indirect) in mind.
Such a person is diverse from those involved in the commercial transmission, public security (for instance, police and firefighters), or expert two-way radio services. In simple terms, amateur radio is a well-known avocation and service bringing people, electrical appliances, and communication together.
The ham radio is used to communicate around the world, or even in space, all these without an internet connection or mobile phones. It can be of great assistance when you need it. It’s amusing, social, and educational.
History of the CB Radio
CB radio was an excellent communication device. It runs in the high frequency (HF) radio wave specter (3 to 30 MHz). Therefore, CB signals can ricochet in the atmosphere and become global communication tools.
In the 1970s, atmospheric conditions were mature for CB signals to “skip” and travel longer distances. These days, CB signals don’t skip and travel long distances because of poor conditions.
VHF and UHF radios were expensive for average consumers in the early 1970s. Due to this, many people who wanted to have “wireless communication” opted for CB radios. In those CB radio days, there were 40 channels set aside for the cause.
To ensure frequency utilization was easier, simpler, and more likely to be used well, these 40 channels were channelized. With a multitude crowding into these 40 channels, this only brought the worst of them all. It’s similar to the problems with internet anonymity these days.
The CB radio was readily available for everybody to use since it was modeled as the “poor man’s business communications” by the FCC. The VHF and UHF radios were too costly because mobile phones hadn’t been fangled yet. For off-roaders, CB radio communication rapidly became the status quo.
The CB radio is intended for people who would like to have an avocation in radio communication without a license. Usually, the CB radio is mobile and short-range.

History of the Ham Radio
Radio waves were initially invented by Heinrich Rudolph in 1888. Ham radios have been in existence since then. However, it wasn’t until after the First World War that amateur radio began getting popular.
There was a limitation on how you could get your ham license up until 2005. To get a license, you had to pass a Morse code challenge and demonstrate that you knew Morse code. The FCC lifted this limitation and allowed Americans to acquire an amateur license without learning Morse code.
This made it possible to use amateur radio frequencies for off-road purposes. This is because many off-roaders don’t desire or need to learn about Morse code.
After the Morse code was eliminated from amateur radio testing, ham radios have become more widespread in the off-road communities. It’s because there are few barriers and, therefore, ham radios are increasingly becoming more accessible.
With the widespread use of amateur radio, countless people are pondering why they should take into account using it for their trail communications over the CB radio.
The amateur radio is for people who want to communicate over long distances, participate in round table on-air conversations, communicate in emergencies, and similar scenarios. It’s a suitable and efficient method of person-to-person communication.

Differences between CB vs Ham Radio
For you to use amateur radio, you must be licensed. In the US, the FCC (Federal Communications Commission) controls the airwaves. You cannot broadcast on ham radio frequencies without a license.
Amateur radios have access to three license certifications that you can acquire through progressive trials. They assess whether you comprehend these radio regulations, principles of radio theory, and how you can operate the ham radio on several channels without disturbing other ham radio users.
On the contrary, the Citizen’s Band (CB) radio needs no assessment or certification. Instead, the CB radio offers a user-friendly method of communication that the general public can use at will. It’s somewhat controlled by the government and needs licensing only for those who are interested in running a station.
Anybody, irrespective of age or experience, can take up the avocation – and there’s no need for an assessment – unless you’re an international government representative, a foreign government, a federal agency, or the bearer of a present FCC’s stop-and-desist order. However, for the average people, the avocation is hassle-free.
The CB radio is limited to a 4-watt power output by the FCC. On the other hand, amateur radio is limited to a 1500 watts power output by the FCC. The ham radio is virtually 375 times more capable than the CB radio.
With that much power running you require a good double battery setup and a powerful alternator. Numerous hard-wired mobile amateur radios operate at 50 watts. It’s still ten times more powerful than your CB radio.
Many portable amateur radios operate at 4-5 watts of power output. Your hard-wired CB radio operates at this power output. And these portable amateur radios are inexpensive. What’s the cost of your CB radio with the same power output?
Several portable amateur radios increase power to 8 watts and even to an output of 10 watts. They’re excellent radios. However, you have to be cautious, with a power output of 10 watts; they’ll drain your batteries pretty fast.
A high-quality portable amateur radio with a power output of 8 watts is an excellent option when it comes to durability and power output.
- Modulation (AM, FM)
Perhaps you’ve seen several CB radios publicized as having 120 frequencies. It’s just marketing hype. CB radios can broadcast amplitude modulation (AM) or single sideband (SSB) signals. An AM signal comprises two redundant sideband signals.
Each of them comprises the voice of the operator together with a so-called carrier signal between them. An SSB signal utilizes only one of the sidebands. The sideband “frequencies” are 40 regular AM channels’ upper and lower halves.
Amateur radio uses frequency modulation (FM). It has numerous benefits when used for ham radio communications. Usually, FM is used where a portable and mobile operation is more common. It’s because frequency modulation has excellent resistance to noise and differences in signal strength.
Due to this, FM has become acceptable and prevalent in the UHF and VHF ham radio bands. Besides, the Ten Meter amateur radio uses FM too. Whether it’s used for ham radios or any other application, the technology behind FM is the same.
CB radios operate at 27 MHz frequencies. If you compare cb vs ham radio, the CB radio channels are fewer than those of amateur radios. The CB radio doesn’t have sufficient power to break through obstacles like mountains.
Lower frequencies similar to those of the CB radio allow signals to travel over mountains. However, this can only be efficient if there’s a higher power output than what CB radios provide.
On the other hand, amateur radios operate on UHF and VHF. The UHF runs on around 440MHz while the VHF operates on about 147 MHz frequencies. Higher frequencies allow signals to pass through obstacles or limitations.
For communication, you can utilize both the UHF and VHF. However, each has its unique features. It’s advisable to use UHF if you’re on the land, water, or in the desert. The signals travel further in these types of terrains, and the result is always wonderful.
VHF offers improved results as far as broadcast and signals are concerned. This is in case you’re in mountains or hills.
Usually, CB radios have a range of 1-2 miles. This range may be more to an occasional 20 to 25 miles. It depends on the aerial and atmospheric conditions like solar flares and propagation.
If there’s an obstacle between the receiving aerial and the broadcasting antenna, communication may be interrupted. It takes place if one or more CB radios in the group or team aren’t stable, particularly, when users move from one location to another.
Amateur radios cover both short distances spanning the town as well as world-wide international communications. Ham radio operators can also communicate with cosmonauts who are located at the International Space Station.
If you compare the ham radio vs cb radio, CB radio aerials must be at least 102 inches (8.5 ft.) long to function properly. If the antenna is shorter than that, then you’ll need an SWR meter. You should also tune it to work effectively on the range of 10 to 20 frequencies.
The firestick is a well-known CB aerial. However, they’re usually about 48 to 60 inches long. Therefore, how can they work if a CB antenna has to be 102 inches long? Firestick wraps the aerial wire up around the center that’s made of fiberglass.
If you look at a firestick aerial, you’ll perceive the wire enfolded up to the top of the aerial. The cable wrapping is known as coiling. If you coil your aerial wire more, it’ll work on fewer channels. It implies that you have to take some more time, spend more cash, and effort tuning your CB aerial using an SWR meter.
On the other hand, amateur UHF and VHF antennas only need a minimum length of 19.5 inches. As the minimum is smaller than CB minimums, you don’t have to tune the aerial because you’ll get the complete spectrum range on UHF and VHF.
Many amateur radio aerials are ready to use from the factory and don’t need tuning. As an off-roader, it’s suggested that you get the 37 to 39 inch-amateur radio aerials. They provide more signal amplification (gain), and they’re still shorter as compared to most of your CB aerials.
Therefore, in a less invasive space, you get improved performance. You’ll have unlimited attachment options for amateur radio antennas also, due to the aerial size.
Conclusion Ham Radio vs CB
Comparing a CB radio vs ham radio is similar to likening one band to 26 bands. The crucial point is in determining your aim of using radio technology. If you only want to operate in short distances, the CB radio is your best bet.
Most people usually begin with a CB radio and then realize that they need more. Amateur radio can be easy or complicated as per the operator’s desires. It’s an enormous avocation with more than two million ham radio operators around the globe.
Both CB and amateur radios have diverse features. Determine your purpose, and then select the radio that’s suitable for your communication style.
