CB Radios Vs. VHF

While both these communication devices serve similar purposes, they’re not the same thing at all. People use both these terms interchangeably, but they’re actually quite different. Let’s take a look at their differences.

CB Radio Vs. UHF Vs. VHF (2)

The Differences

While both the communication devices are used for the same purpose, communicating, there’s a difference between their functionality.

CB radios are most known to be a part of the disaster preparations toolkit. Whereas VHF radios, also known as Marine radios, are mandatory for boating purposes. It’s in the name.

Another difference between the two communication devices is their main user base.

CB radio or the Citizens’ Band Radio is famous amongst truckers. Truckers mainly use this two-way radio for any traffic update or to keep in touch with the other truckers on the road.

On the other hand, CB radios are the bread and butter of truckers and other drivers. Since this radio has an emergency channel, truckers and other drivers can keep themselves updated with the latest news on the traffic.


While both these radios have similar names, they carry some distinct dissimilarities as well. Here’s a breakdown.

CB Radio Vs. UHF Vs. VHF (6)

The Differences

Although the UHF radios work as a means of communication amongst public safety officials, the mariners are the primary users of the VHF radio. In fact, VHF radios are a must-have for any water cruisers out there.

Since the radio bears no connection to the electrical part of the boat’s system, even in the wildest storm, the VHF radio can function quite well.

CB Radio Vs. UHF Vs. VHF (7)

In the case of UHF radios, their ability to go through any type of barrier makes them the first choice of public safety officials. With the help of the UHF radio, the first-responders can communicate with the rest of their teams and keep everyone updated with the latest situation.

CB Radios

Just as zoom and google meet are all the rage nowadays, CB radios were the buzzword of the earlier generation. With some of the most exciting features and very reasonable pricing, CB radios were popular amongst all.

While its popularity has waned in the past few years, that doesn’t mean that it’s just an obsolete tech now. Instead, to this day, CB radios have held onto their popularity amongst their vast user base.

The Citizens’ Band Radio is commonly associated with truckers, but it’s popular amongst anyone on the road.

Operating on the AM and SSB band, the CB radio has a dedicated channel that reports on the latest updates of the road and other traffic-related issues. So, if you have a CB radio and you’re on the road, you don’t have to worry about which route to take. Just tune in to channel 19 in their band, and the news will come to you.

Another exciting feature of the CB radio is the emergency announcements channel. This channel is dedicated to delivering the users with the latest emergency news, which is why most boats carried a CB radio before setting sail. That way, they could stay ahead of any emergencies and take shelter if needed.

Legal Requirements

As stated before, you don’t need a license to operate a CB radio. However, there are a few restrictions regarding the use of a CB radio.

CB Radio Vs. UHF Vs. VHF (9)

First, the FCC has forbidden the use of CB radios by any foreign government officer or representative. Additionally, you must comply with the order if the FCC has issued a cease and desist order against anyone using a CB radio.

When to Carry

It’s a good idea to have a CB radio in the car if you’re going to stay on the highway. Truckers use the Citizens’ Band Radio to keep track of any construction zones, road closures, and police stops. Besides these, CB radios are also suitable for contacting others if there’s no mobile network coverage.

UHF stands for Ultra High Frequency. Just as CB and VHF radios have a primary user base, UHF radios have a primary base.

Thanks to its high frequency and shorter wavelength, UHF radios can work through different types of barriers, making them the first choice of public safety officials like fire brigade, police officers, and many more.

UHF is best suited for indoor uses with a wide range and the ability to go through different obstacles. Or you can use them around cities where there are buildings obstructing signals.

While other radio signals will be blocked by the concrete and steel barriers, UHF radios can pass signals through these obstacles without any difficulty.

Additionally, UHF radios need shorter antennas to work. This shorter antenna adds to their portability and makes them perfect for discrete two-way radio devices or circumstances where a shorter antenna will work better.

For example, if you’re a safety official working in the crowded hallway of a school, a long antenna may get in the way of your work. In such situations, a UHF radio works the best.

Legal Requirements

The Federal Communications Commission requires all UHF radio operators to be educated when it comes to legal requirements. Likewise, the users need to be educated to operate the radios correctly and not to end up interfering with others’ signals.

So, if you’re using a UHF radio, the FCC states that you need to have a license for such an operation. However, you won’t need any permit to buy the equipment. Truth be told, a lot of users don’t end up getting a license under the pretense that they simply didn’t know.

When to Carry

While the primary user base of UHF radios is public safety officials, it doesn’t hurt to carry UHF radio with you as a part of your emergency preparedness toolkit. As UHF signals can go through wood, concrete, and steel, you can send and receive signals during times of emergencies.

Of course, the term emergency refers to actual emergencies, as in life or death situations or something equivalent. You should never dial up your UHF radio to let your boss know that you’re not coming in today. Such careless usage can lead to you being fined or worse. So, keep it on you at all times, but use it carefully.

Highlighted Features

  • Signals go as far as the user’s line of sight.
  • Features shorter antennas to create shorter wavelengths and higher frequency
  • Wider frequency range
  • Frequencies are pre-assigned


Maybe you’re planning a trip to clear your mind and relax. You may think you’ve everything you need but do you. But have you picked up your two-way radio? Of course, nobody wants to believe anything terrible may happen to them, but it’s essential to be prepared.

So, before you leave for the fishing trip with the boys, you better take your VHF or marine radio with you. Who knows? It may just save your life!

Like its CB and UHF counterparts, the marine radio also has a primary user base. You probably guessed from the name: marines.

Mainly used for weather updates, distress calls, and navigating their vessels, the marine radio is perfectly suitable for the occupants of the sea. As the two-way radio system isn’t connected to the ship’s electrical system, the radio can still work even if a storm knocks out the ship’s power.

In fact, there’s a specific channel that’s dedicated to such distress calls. So if a mariner is ever in trouble, they just have to turn to channel 16 on the VHF band and ask for help. The channel is always kept free all day and night long to immediately respond to any potential distress calls.

Legal Requirements

If you’re just cruising around in the water just for fun, you can have a VHF radio on your boat for safety, and you won’t need any licenses. However, the FCC requires you to carry a VHF license if operating a larger boat and have employees on board.

CB Radio Vs. UHF Vs. VHF (14)

To get this license, you need to be able to speak English and be a resident of the US. After that, you’ll need to sit for multiple exams to get the license.

When to Carry

As a general rule, remember this, if you’re ever in the water, you need to have a VHF radio with you. The marine radio is crucial for saving your or anyone else’s lives on the unpredictable water.

Apart from emergency calls, the VHF radio is an excellent tool for navigating your ship safely. After all, you can never be too cautious, no matter how experienced you are.

CB Radio Vs. UHF Vs. VHF (15)

Just as channel 16 is dedicated to emergency calls, the VHF band has another channel dedicated to navigational purposes. The larger ships and boats announce their presence to other boats in this channel. That way, you can stay out of their way to not crash into them at any point.

Highlighted Features

  • Dedicated channel for distress calls
  • Range goes as far as the user’s line of sight
  • Dedicated channel for navigational purposes
  • Wide range of pricing options

Final Words

That was everything on the CB radio Vs. UHF Vs. VHF. In a nutshell, CB radios should suffice. But if you’re expecting interferences, go for UHF radios. And if you want to use your device in an open space, VHF radios are the way to go. You will, however, need to get a license to use them.


Should I use VHF or UHF? ›

The only time you will want to use VHF is if you are outside in a wide-open space like a field. VHF has smaller frequencies which means interference with other radios is common. UHF, on the other hand, is an all-around better signal for long distance communication.

Which goes farther UHF or VHF? ›

VHF radio signals are on the low end of the frequency scale when compared to UHF. Although, VHF signal wavelength is longer, allowing it to travel farther than UHF.

Is VHF better than CB? ›

Pros of Two-Way VHF Radios

The range of professional two-way radios can vary from as low as 2 km to 25 km in range. Conversations over two-way radios, in general, is generally slightly better than CB Radio, as there is less interference and because of the small form factor, they are easy to carry.

Is UHF or VHF better in woods? ›

UHF signals don't travel quite as far outdoors as VHF signals, but they do a better job of penetrating wood, steel, and concrete, giving you better range and performance in urban environments and around buildings.

Do police use VHF or UHF? ›

Police radios operate in a 700/800 MHz UHF band.

Can UHF penetrate walls? ›

UHF radio waves generally only go as far as line of sight. Anything in the way of your sight will also interfere with frequency range, such as buildings, tall trees or any other obstruction. The transmission is high enough to penetrate through building walls, making indoor reception a possibility.
