Buyer’s Guide

If you want to listen to the radio but your car audio device works unsatisfactory, then a separate radio-frequency amplifier should be considered to improve the broadcasting reception. However, to make the best decision possible, you need to know some basic guidance for choice to avoid any performance issues in the future.

Before giving your preference to this kind of equipment, you should also make sure it is legal in your area. If you are going to use an amplifier for CB radio in the USA, you will break the law. It can result in large fines and/or seizure of the equipment.

Talking about the common base amplifier, its input node is emitter terminals, while the output node is the collector terminal. The base is basically grounded. There are a couple of things that differentiate the amp’s circuit from ones of alternative classes. For instance, it is a base capacitance connected from the base of the transistor directly to ground. Basically, what that capacitance is doing is creating an AC ground connection for the base. In this perspective, CB provides a short to ground for AC signals, while the emitter resistance is needed for circuit operation. It is though included to provide a path for the DC bias current.

Due to its construction, the CB amp has a very high voltage gain, but it doesn’t possess a current gain. The latter is to equal current out, and since the emitter and the collector are applied, the final parameters differ. At the same time, AV and AI characteristics allow producing a good power gain. In simple words, it will work well for high and super high frequencies.

Overall, there are three types of CB amplifiers. You should choose the most suitable one in accordance with your usage purposes. The first class is linear CB radio amplifiers. They work with the outgoing signal on a connected tool. The second case is valve radio frequency amps. Their particular function is maintaining high-power transmitters. Finally, if you need to improve and enhance the information received by antennas, you are to give your preference to common-emitter amplifiers.

When selecting such device, bear in mind some important parameters:

  • The operating band must cover the desired frequency range.
  • The amplitude-frequency range has to be as uniform as possible.
  • As for the gain, the desirable range is within 15-25 dB.
  • With a spread of supply voltages, a stable operation must be ensured.
  • The dynamic range has to be great as well. This feature contributes to the overall protection against overloads.
  • The noise ratio must be less than signal-to-noise ratio.

You should pay attention to the gain ratio as well. The fact is that the reception quality may be not high with its small values. So, this parameter should be high enough to improve the reception quality but not overestimated, since overload can simply damage the device.

We would also like to highlight that the best effect can be achieved if an amplifier is connected to an external antenna. Thus, an active rather than a passive dipole is connected. Equally essential is the distance to the signal source: you can hardly count on high-quality reception if the station (main transmitter) is located at a distance of more than one hundred and twenty kilometers.

The CB amplifier is specially designed for efficient and reliable reception of radios. Most customers review that the signal has doubled with the use of such device, if not more. To note, this equipment doesn’t require any special installation skills. Its setup consists of connecting one end to the head unit and another end to the external passive dipole. To ensure stable reception and interference protection, it is recommended to install an amplifier closer to antenna. If you set it up next to the radio, the interference level generated by automobile electrical equipment will increase.

On the top of that, CB amplifiers are multifunctional equipment designed not for radio use only: they are also applied to enhance the production of smartphones, PCs, laptops, DVD or other gaming devices, as well as televisions.


  1. What is a CB amplifier?

By this notion, we mean a special transistor construction where input and output signals are operated by the common terminal

  1. Is it possible to enhance the CB output?

Yes, it is. First of all, you can modify the radio mechanism itself by using an external antenna. Secondly, you can use special CB amplifiers to improve the device’s productivity.

  1. How many watts is a common CB radio?

Overall, this parameter equals four watts and is determined by the Federal Communications Commission (FCC). However, SSB radios are more productive: they are approximately twelve watts.


All in all, even though CB amplifiers are not the most commonly used machines, their features make them unique and convenient to improve sound quality and audio harmony. With this list of the best solutions, you are welcome to enjoy your favorite hits in the brilliant performance. Check it out and see for yourself!
