You might be wondering how can you find the ‘one’?
You don’t have to do anything. We have done the hard work for you! This article will give you the right amplifier for your CB radio which will create an outstanding experience.
If you are eager to know those high power CB amps, here is a quick overview:
Best CB Amps
What is a CB radio Linear Amplifier?
Weak signals are always a headache for any CBer, limiting the operation of the CB radio. This is where a CB amplifier comes to your rescue by boosting the signal.
Having a CB amplifier will enable you to reach many more miles away with your CB radio. A CB radio amplifier with proper aerial tuning offers you a surprisingly good connection.
A linear CB amplifier is not a power-efficient amplifier. On the other hand, it does a great job in dealing with noises. Since CB radios don’t need high power amplification and their main concern is the noisy environment, having a linear amp for CB is the most ideal choice.
High power radios available in the market these days are not affordable for everyone. So if you are desperately in need to improve the power of your CB radio without emptying your purse, a CB radio amplifier is definitely something that is going to save you.

Do consider the following before jumping into a decision to buy a CB amp.
Stick to the rules
The maximum power output allowed by FCC (in the US) for CB radios is 4W for AM/FM and 12W for SSB. When you choose a CB amp, make sure that its input rating falls within this range.
Also, your power boosted CB radio has to operate within the 20MHz to 30MHz range within which CB radios fall.
But this is not the case always, most CB amps operate at a higher power of 150-500 Watts. If you ask me, if it’s illegal, it’s of course illegal. But how many people were put behind bars for doing so?
Major features to look for
Look primarily for the following features when you choose your CB amp
- As the CB amps heat up significantly during its operation, air-cooled and heat sink attached CB amps may be preferred.
- How major parts like antenna, buttons, and cable connectors are placed in the layout is important in terms of accessibility.
- Inbuilt protective features like auto short circuit and over-voltage shut down protection are real money savers.
Optimize your current setup
You don’t always need to boost the power of your radio to attain more range. If you properly tune your radio and antenna system you can easily do the job.
Why waste your money on an amplifier if you could talk farther by optimizing your current system set up correctly?
A CB amp will come to your rescue only when you need to talk even farther.
Can your current system handle more wattage?
Before buying an amplifier, know the maximum wattage rating of your antenna. What if your antenna is set to handle say 150 watts only and you run 300 watts into it? If you care for each penny spent on your device, this is not at all a good idea.
Amplifiers require a substantially huge amount of electricity to power up your antenna. Know very well how much power input you can give. You can’t bite off more than you can chew.
The compatibility of your radio with the CB amp is important. An incompatible amplifier might not withstand too much input from your radio. You might easily ruin your CB amp that way.
How much power do you need?
This has to be decided based on the talking distance you aim to achieve. But most of the cases, you don’t require more than 500 Watts CB Amp.
You will find more on this later in this article.
You want to talk over AM, SSB, or both?
Distortions are very common in AM communication and hence can be ignored. Hence any of the CB amplifiers available in the market will work decently with your 40 channel AM-only radio.
On the other hand, if you are planning to use a CB amp for SSB, features like delay and amplifier class need to be taken care of.
Do you need 1000 & 3000 Watt CB Amplifier?
No, you don’t! Powering up your equipment to multiple thousands of watts wastes power and increases the likelihood of causing interference to nearby radios, televisions, telephones, etc.
Hence one must use the minimum power required to carry out the desired communications.
100 watts is enough!
We all know many CBer’s who take it too far to power up their equipment to multiple thousands of watts. But that is totally unnecessary for most people. If you clearly know what you are trying to achieve with your CB radio, it is easy to figure out how much power you need. Generally, for most people, a 100 watts amplifier is more than enough.
The magic number
100 watts surprisingly is a magic number when it comes to choosing what power CB amplifier you need. That much power is enough to save you when all you need is to talk a little further without spending too much effort or money.
Going from a normal 4 watts to 100 watts can yield you almost threefold more coverage. So if you could reach up to say 20 miles with 4 watts, now you can reach up to 65-70 miles easily with 100 watts.
When you go with your friend on trekking and you face difficulty in hearing each other over a few miles, a 100 watt can easily serve you with a solution. CBer’s can also enjoy clear transmissions across amazingly large distances via DX (skip) on busy days using a simple 100 watt.
Do not go beyond 450 watts
You need to understand that 450 watts is where a limit is set.
The maximum practical gain in distance is achieved by using 450 watts. There is no point in trying to go beyond 450 Watts if you want to talk farther.
A solid 500W CB amplifier should be accurate for the best practical distance results.
Being heard by someone else on the radio is an uphill battle in today’s CB world. Unlike in olden days, there is a significant uprise in interferences and the CB radios are not really built to cope up with that.
Modifying CB radios for more power and hence longer coverage is a need of the hour and CB amplifiers do the job perfectly and pocket-friendly.
I believe I have succeeded in helping you find a powerful CB amplifier to cross those extra miles.
