CB Amplifier Buying Guide
Before you make a purchase and enhance the work of CB radio, you should be aware of a few theoretical nuances. I invite you to read them before purchase.
Why need CB Amplifiers?
You need a CB amplifier if you have a CB radio and would like it to be more powerful.
CB radio can produce poor quality sound, especially if you use a radio in a big city. High buildings, a large number of people, and even open windows in a car can spoil the sound quality.
If a high-quality sound is important to you, the CB amplifier will be a great device that will make the sound professional.
Types of CB Amplifiers
Before buying a CB amplifier you need to know about types.
The matter is that there are several types of amplifiers and each of them has its own classification.
For example, one type will be useful for amplifying the sound, while the other will amplify the signal.
Depending on what you lack when you use CB radio, you need to choose an amplifier type.
According to one (the most common classification) CB amplifiers are divided as follows:
- CB linear amplifier
- Valve RF amplifiers
- Common-emitter amplifiers
A CB linear amplifier is the most popular thing to amplify an outgoing signal.
The second type of amplifier is good for powerful signal transmission. And I would recommend the third type of amplifier for a signal that is poorly picked up by the antenna.
In most cases, people who want to get better performance from an amplifier, opt for a CB linear amplifier.
The fact is that this amplifier is the most powerful of all the above mentioned. For example, using a linear amplifier, you cannot worry about the distance between you and the person who receives your signal.
But besides this classification, there is another one. According to the second classification, all amplifiers are divided into several classes, namely:
- Class A
- Class B
- Class AB1
- Class AB2
- Class C
At first glance, it seems that everything is as difficult as remember all different types of gas masks, but this is not so.
Class A amplifiers are weak amplifiers and make only 50% of what other amplifiers do. But amplifiers of this class can reproduce the signal very well.
Class B amplifiers are more efficient than Class A amplifiers and require high power because that only hold half of the input signal.
Class AB1 is characterized by a grid offset. In this case, it is shifted negatively to class A.
In the case of class AB2, it is opposite to class AB1 because the grid is displaced negatively than AB1 and because the current will increase if the grid is made positive. Accordingly, the power of this class is also higher.
Both AB1 and AB2 work better than the A and B classes but transmit a signal worse.
And finally, the most powerful and effective amplifiers belong to class C. As a rule, these are non-personal amplifiers and are not suitable for all radios. You can use it for FM, CW, RTTY modes.
Such a class has disadvantages as high distortion due to amplification of the output signal (higher than the input signal), and this reproduces the signal worse than class A’s amplifiers.
The best amplifiers for linearity and reproducibility of sound are class A’s amplifiers. But amplifiers of other classes will be more efficient.
So, there is a paradox. You get more efficiency and a distorted signal, or you get low efficiency and a great signal. What to do?
You have two choices: a) come to terms with life and continue to live on, b) use feedback or direct connection or DPD and some other additional circuits along with amplifiers of classes A and B.
What Does A Linear Amplifier Do?
CB radio transmits low-frequency signals. And the situation may worsen if you live in a larger city because a big city can make big interference in the radio operation.
A linear amplifier improves the signal quality and also increases the distance at which you will catch the signal.
Experts claim that the correct tuning of the antenna can give a good connection for 8000 miles. This is quite a lot.
Are CB Linear Amplifiers Illegal?
It may seem strange or even funny, but the CB linear amplifier is indeed illegal.
Firstly, it is illegal not everywhere, but in some states of America and in some countries of the world. Before buying a CB linear amplifier, it will be logical to know whether it is legal to use an amplifier in your state or country.
As you probably already know, many people live in places where the CB amplifier is illegal and this does not prevent them from being interested in the radio and using stuff to improve the signal. Why?
There are several options: a) they are not afraid to pay a fine or even become imprisoned, b) they know that few people have problems with the FCC because of this.
If you use the CB linear amplifier wisely, you will have no problems. And if you are going to listen to music and exceed the allowable power (for example, 1000 W), someone from the FCC will come to you for a “pleasant conversation” and a fine.
Interpol will not search for you immediately after you buy an amplifier. And it will continue as long as you create problems.
It is important to remember: the permissible power when using AM is 4 W and when using SSB it is 12 W.
Features To Look For During Purchase
If you decide that you are a daredevil and are ready to “cross” the law, your “illegal activity” must begin with a very high-quality product. How to get a quality CB amplifier? For example, this is a CB linear amplifier which has the qualities listed below.
Compatibility with CB radio
Compatibility with CB radio is the most important choice. If the amplifier cannot be combined with the radio, you do not need such an amplifier at all.
I have already said that the FCC expects from you that you will not exceed the maximum output power of the radio, namely 4 W and 12 W.
Therefore, the input power CB of the linear amplifier should be in the region of these values. Plus, the frequency, which can be in the range from 20 MHz to 30 MHz, is also important.
If the CB amplifier that you choose has all this, then everything is OK
This item is very important because you buy an amplifier only for this.
Amplification is how the CB amplifier makes the sound better. Therefore, the higher the gain the better.
I advise you to check this item through careful study of the brand and its characteristics, as well as through the study of reviews.
The quality can be badly damaged if you install it incorrectly and you will hardly use it.
Paying attention to the design, I would highlight the following points:
- Availability of radiators and ventilators
- Antenna cable and button connectors
- Reverse polarity protection (but let’s talk about it later)
Why do we need radiators and ventilators? They are needed to make the cooling function if the amplifier has it.
And connectors and buttons are needed to connect the amplifier to the radio. If not, why do you need a brick?
Almost all CB linear amplifiers are miniature in size and do not interfere with use. You can put it on the floor or under the radio.As for weight, it is also easy to carry.
CB linear amplifiers heat up when you use it. And if the device is hot, its performance is not good.If the heating is very strong, some parts may even melt.
Therefore, the linear amplifier that you are going to buy should be equipped with a ventilator (at high speed) or some other cooling feature.
Here the rule works: the more modes, the better. However, I doubt that you will be able to find a CB linear amplifier with a small number of modes. The fact is that almost all existing amplifiers are “stuffed” with all possible modes.
Reverse Polarity Protection
We said a little about this.
It would be better if the amplifier you buy will have protection against polarity reversal. Fortunately, most devices have this feature.
These could be some kind of diode or DC-powered circuit, a wire that protects the circuit, and so on.
I know that we are not considering headphones. So why do you need a noise canceling in it?
This feature allows the amplifier to suppress background radio noise, which usually occurs when there is no signal.
To get rid of background radio noise, all you have to do is turn on the noise cancellation and keep it on until the noise goes away.
Generally, this function will keep your receiver quiet and nothing will annoy you.
This is another mandatory feature for which you buy an amplifier – an increase in output power during signal transmission.
Output power should be more than 150 watts and this will be the case in most cases (although sellers talk about 250 watts or even 300 watts).
There are several best-known brands that are always popular and people buy them more often than products of other brands. What are these brands? More I will tell below.
The price may be completely different. It depends on the quality, a number of functions, and power.
I do not advise to pay attention to a price when choosing the best CB amplifier. First of all, pay attention to the functions, and then to the price.
How to Build a Linear Amplifier for a CB Radio?
Linear amplifiers are a cool thing that improves the quality of the incoming and outgoing signal, and more. But if you build a linear amplifier, you will get even more options.
In addition, if the amplifier breaks once, you can fix it by yourself, since you already know everything.
So, you can build a linear amplifier as follows:
You will need a chassis, a frequency meter, a power supply, and connectors. Fortunately, all the necessary parts are sold in the kit, so be attentive in the store.
It is better to buy the parts in the kit because that is the same size. It will deprive you of unnecessary moving.
Check This Out
If the parts are not new, then make sure that there is nothing oxidized and cracked. If there is something with a defect, then replace it.
Be Sure About The Chassis
At this stage, you need to calculate the area of the frequency meter and IEC power supply.
Then cut out the rectangular holes that will be used for the frequency meter, the IEC socket. Plus, with an electric drill, you need to make a mounting hole on all sides (choose a 4 mm drill bit).
And remember that the meter should be located at the front and the power connector at the back.
Before Connecting The Circuit
Clean the tip of the soldering iron. Use a damp sponge for this, and then coat with a cotton cloth.
Remember that resistors, transistors, capacitors, potentiometers, relays must be considered. Each of this is inserted into the appropriate connector and do not abuse the pressure, because it must be optimal.
Flip The Circuit Board
So that the front side looked down.
After that, press the connector pins to its flat state on the metal strip. Then solder all the connectors on the strip and screw the circuit board into the base of the case.
It Is Time For The Power Wire
Solder it to the output connector of the frequency meter. Then proceed to the wire at the output terminal of the IEC power supply.
At this point, start setting the frequency meter, IEC power source, and jacks that you soldered in the previous step.
Now you need to connect the frequency to the potentiometer, and the power source must be connected to the positive eyelet of the board.
The ground wire should be attached to the negative eye on the board, and the input connector to the eye in front of the first resistor.
Finally, the output connector should be soldered to the eye after the last resistor.
The final step
will be – tightening the chassis cover.

How to Install CB Amplifiers?
It was difficult to build an amplifier. Believe me, with the installation of a CB linear amplifier everything is much simpler.
Step 1 – Check Antenna Position
Until you check the SWR meter, you do not have to connect the amplifier to the radio. If the SWR is bad, it will break your CB radio.
Step 2 – Place The Amplifier
This is important. You can put it next to the radio, put it under it or on the floor. If you are going to put the radio nearby, please be sure that there are 3 or 4 inches of free space (for adequate ventilation).
Often, amplifiers can be installed with radio mounting hardware, but this is the case with mobile use.
Step 3 – The Connection Preparation
Now you need to disconnect the antenna that was connected to the CB radio up to this point. By the way, what you just unplugged is called a coaxial antenna cable. Now connect this cable to the antenna jack on the amplifier.
What to do with the free CB antenna jack? You need to insert an amp jumper in there.
The fact is that this jumper has two ends. The other end should be connected to the input jack on the CB linear amplifier.
Step 4 – How About The SWR Again?
You need to check the standing wave ratio again. It is important that this indicator does not change.
It is good if nothing changes. And it is bad if something changes, then you have to fix the problem. Connect the SWR need as it is stated on the amplifier.
Step 5 – Direct Connection
Now just take the power cord from the amplifier and plug it into the wall outlet. Then turn on the power and the amplifier should start its work.
If you have a mobile device, the red power cord should be connected to the red cable and the black one to the black power cable on the CB radio.
Top 4 CB Amplifier Brand
Everyone asks, “WHAT BRAND IS BETTER?”
This is difficult to answer because functions are primary things, and the name of the product is only of secondary importance.
But I will allow myself to recommend several brands to you:
This brand makes amps for portable CB radio. Usually, the products of this brand are compact and light.
In the amplifiers of this brand, there is almost everything: it can withstand up to 30 MHz frequency, has a solid construction with a ventilator for cooling, conveniently placed buttons, and automatic switches.
Additionally, this brand can be used with any CB radio, the signal of which can be improved up to 300 watts.
The amplifier from this brand has a durable aluminum body, power indicator, a few buttons, and antenna connectors. But you can use this brand for AM / FM and SSB.
And this brand incorporates reverse polarity protection, a ventilator in amplifiers.
Firstly, this brand makes a very compact and lightweight amplifiers. It is suitable for CB radio, FM/AM and SSB.
And then everything is standard – the ventilator, radiator, range up to 30 MHz. If you use the amplifier of this brand, you can get power up to 250 watts.
These are the same lightweight and compact amplifiers, the voltage of which you can easily adjust. You can also use the amplifiers of this brand in parallel with other power supplies and get a current from 50 to 200 amps.
Care and Safety of CB Amplifier
- Install a CB amplifier in the room that is ventilated, because the amplifier, as an electron device, can be hot and interfered with.
- Since the CB amplifier is an electronic device, it is important to install it in a dry place so that no water gets on it.
- Always be confident that the antenna can withstand maximum output power. If everything is OK, then the new amplifier will work for a long time.
- It is cool if you have an amplifier or radio with a microphone in the kit because this will allow you to tune the radio with an amplifier.
- If you choose a microphone, it must be with a noise reduction function.
- If you want to set up a CB radio with an amplifier, send it to an open area where there are not a lot of people and skyscrapers.
- When setting up a CB radio with an amplifier in the car, the windows, doors, a trunk is closed, because all this can knock the signal off.
What is a CB radio linear amplifier?
This is a device that takes the standard CB radio output (typically 4 watts) and then boosts it to a much higher power level. If your CB radio is limited to just transmitting to people in town, then with the amplifier you may be able to transmit to the next town over.
How Do I Know That I Can Use A Linear Amplifier?
If the CB radio and the linear amplifier are compatible according to the characteristics, you can use such an amplifier without problems.
Another thing is whether it is legal in the place where you live. But even if it is illegal, you can use a linear amplifier and not exceed the permissible power. An amplifier can help you avoid interference when receiving a signal anyway.
Are CB amplifiers illegal?
Technically, they’re illegal. In theory, the FCC can fine you for the offense and even jail time is a possibility. At least, that’s the theory.
In real life, thousands of people use this and none of them have been hassled by the FCC. You’re just breaking the law that no one really cares about. It’s like jaywalking when there are no cars around.
Why do truckers use linear amplifiers with their CB radios?
The most basic reason is that they’re able to communicate with more CB radio users. The amplifiers boost the signal, so that they’re now able to talk to even other truckers from farther away. Most truckers can’t use the best antenna for their CB radios, so they compensate with linear amplifiers.
How do you amplify a CB signal?
The transmission power of the CB radio is quite low. To amplify that you can use the linear amplifier. It improves the transmission range to get a long-distance broadcast using the CB.
How can I make my CB radio more powerful using CB Amp?
Using the CB amp, you can get the transmitting power of your radio to go up more than the usual 4 watts. And more watts means, more range.
How many amps does a CB radio draw?
According to the test, it draws 0.3 amps squelched, and for full audio output, it is 1.2 amps.
What is the best method to improve input impedance in an amplifier?
The best approach is to create an impedance matching network or a preamp circuit to improve input impedance in an amplifier.
What Is The Best CB Linear Amplifier?
The ideal linear amplifier is one that is not visible to the FCC. Joke!
The best linear amplifier for CB radio is one that has a constant gain at different values of the input signal, remains independent of frequency, and does not add noise. The ideal linear amplifier is not subject to temperature change, it remains stable even if it works for a long time.
Actually a high-quality amplifier with “iron nerves” is a good investment, especially if you are a fan of the radio.
It seems to me that it is much more convenient to use the amplifier than to suffer from a long antenna or change the radio circuit. Setting up the best cb amplifier takes a few minutes and leaves you satisfied with the signal quality. I wish you that!
