Buying Guide: How To Choose The Best CB Amplifier

With tons of CB Amplifiers on the market, the main challenge becomes settling on the right one. Definitely, you should base your buying decision on logic more than emotion.

But when you have no idea how to choose the best CB amplifier, it becomes impossible to make progress. To help you save time and find the right amplifier, here’s what to look for.

1. Federal Communication Commission (FCC) CB Radio Regulations

According to FCC regulations on personal radio services, CB radios should be short-range and low powered. Therefore, a CB radio is only allowed to operate at a power output of between 4 to 12 watts.

This maximum output power is determined by the type of transmission. For AM transmissions, the power level should not exceed 4 watts, while for single-sideband transmissions, the maximum is 12 watts.

Since CB radios operate at a frequency range of 20-30 MHz, the most compatible amplifier to use with a CB radio should also operate within the same range.

These regulations also require that only the permitted power input from amplifiers should be used with CB radios. Therefore, the appropriate CB amplifier should be the one that meets this threshold of power input.

Also, FCC requires that every manufacturer should get certification for their amplifiers before releasing them into the market. And that they should clearly use labels to show the amplifier is FCC certified.

Therefore, our top 3 recommendations are MegaWatt S-400-12, HYS Ham and HF Amplify. This recommendation is based on the fact that these amplifiers operate within the FCC CB regulations for a maximum input power of 5-10 watts. The other consideration is on the permitted frequency range of 20-30 MHz.

Purchasing any of these three CB amplifiers will be a great investment since you’ll get value for your money.

2. CB Amplifier Output Power

The output power determines how powerful and effective the amplifier can be. Thus it goes without saying that the higher the output power the more powerful and effective the CB Amplifier. And the lower the output power, the less powerful it is.

Therefore, we’d recommend MegaWatt S-400-12 at 430 watts, MegaWatt S-350-12 at 360 watts, and MFJ-260 at 300 watts. Any of these CB amplifiers will not let you down based on their high output power.

3. CB Amplifier Cooling Option

Due to the high energy emitted by amplifiers, they tend to heat up so fast. If this is not taken care of, the amplifier is likely to malfunction. For that reason, manufacturers are advised to fit their amplifiers with the right fans to cool the system.

While some fans are effective, powerful, and efficient for the role they play, others fall below par and never make a significant difference. Moreover, some fans are noiseless during operations while others produce a lot of irritating noise.

All these amplifiers have a cooling system. The only difference lies in their performance and how advanced they are. For that reason, we’d recommend HYS Ham HF Amplify.

It has an additional fan installed on the top that provides an additional cooling effect. Also, it’s the only CB amplifier with a fan on its top.  Therefore, this makes it more effective at cooling down the system from high heat dissipation.

However, the main shortcoming is the loud noise the extra fan produces. But there’s a quick solution to this. You can either decide to install the powerful but loud extra fan or install the less powerful but almost noiseless fan. The choice is really yours and based on personal preference.

4. Ease of Transportation

CB amplifiers have different sizes, shapes, and weights based on the manufacturer’s choice of design and construction materials. All these considerations influence the portability of the CB amplifier in one way or another.

These amplifiers have a compact design, metallic protective shield, and a rectangular shape. All these have an influence on how easy or difficult it can be to transport a CB amplifier.

Thus, based on the above considerations, all of the seven amplifiers weigh under 3 pounds which is considerably lightweight and easy to transport.

However Kinter MA170 and BTECH AMP-U25 weigh under 1 pound. This makes them the lightest and the easiest to transport.

5. Cost of CB Amplifier

While some CB amplifiers are quite costly, others are affordable. The most important thing to compare pricing with is the functionality of the amplifiers. How much value does it offer? And do I get the value for the money I invest? These are some of the critical questions to ask yourself when comparing prices for the best CB amplifiers.

Here’s the pricing analysis for these CB amplifiers. HYS Ham HF Amplify and BTECH AMP-U25 amplifiers are the more expensive ones, while MegaWatt S-400-12 is somewhere in the middle.

Both Kinter MA170 and MegaWatt S-350-12 are quite affordable if you are on a budget. From this price standpoint and your set budget, you can now settle on the right CB amplifier.

Frequently Asked Questions

Are CB amplifiers illegal?

CB amplifiers can be illegal based on whether the manufacturers have followed FCC regulations or not. According to FCC regulations on CB radio, the allowed output range should be between 4 to 12 watts.

FCC also permits a frequency range of 20 to 30 MHz for all CB radios. Therefore, FCC expects all CB amplifiers to operate within the frequency range of 20-30 MHz and that their input power shouldn’t exceed 14 watts.

The regulations compel every CB amplifier to have an FCC certification and there should be proof for that on the amplifier. Thus, any CB amplifier that doesn’t meet the threshold is illegal.

How many amps does a CB need?

A CB radio requires between 3 amps and a maximum of 4 amps for optimum performance. Normally, CB radios need a direct current of between 9.5 and 15.5 VDC. However, the standard voltage is between 12 VDC and 13.8 VDC.

It’s the required voltage that determines the right amps for CB. The state of operation, i.e. transmitting or receiving a signal, also contributes to the CB amps.

How do I increase the range on my CB radio?

The best way to increase the range of your CB radio is to use an approved CB antenna. The right antenna is correctly tuned to cover the appropriate frequency range and has an impedance of 50 ohms. You can also use feed cables that are compatible with the antenna. Lastly, always remember to keep away from obvious obstructions.

How far does CB radio reach?

By standards, a CB radio can reach up to 20 miles away. But ideally, the range is between 3 miles to 20 miles. The 20 miles range can be covered by two base stations.

So, to get the most range, ensure the CB radio is properly installed and operates on an approved CB antenna.

How far will a 4 watt CB transmit?

Standard CB radios have a limited range coverage of between 3 miles to 20 miles. This is determined by the terrain and other obstructions between two radio users.

Usually, CBS transmit over long distances (20 miles) when there are no obstructions along the way. But only covers a short-range (3 miles) with multiple obstructions like heavily built-up areas.

What is the maximum wattage for a CB radio?

According to FCC regulations, a standard AM CB radio should operate at an output power of 4 watts. However, for CB radios with single-sideband mode, the maximum wattage is set at 12 watts.

Final Words

The best CB amplifier plays this critical role: boosting the performance and enhancing range coverage of citizen band radios. However, it is not just any amplifier that you should go for, but only what the FCC has certified.

This comprehensive review and buying guide should be your clear path to finding a CB amplifier that’s compatible with your CB radio and offers maximum value for your money. It doesn’t get any better than this, but you need to take action now.
