CB Radio Amplifiers

Citizen-band (CB) radio is a great way to communicate over short distances without having to use a telephone or computer. However, its weak signal is easily overwhelmed when there are stronger signals in the area, making it difficult to hear what other people are saying. One solution to this annoying problem is to use a CB radio amplifier. Unlike the amplifier in a sound system, this one is used to boost the outgoing signal rather than the incoming one. A stronger signal delivers clearer reception over a greater range, making it possible to talk with others who are further away. There are many countries where it is illegal to use one so you need to check with the authorities first.

CB radio has been around since 1945 but it only became popular during the 1970′s, when it was featured in several popular movies and television shows. Since those heady days, the popularity of CB radio has fallen greatly due to the growing usage of computers, mobile phones, and the internet. Still, there are many enthusiasts who use CB radio every day, along with many businesses who have found it to be a good way to communicate with their employees on the road. One important point to remember is that CB radio is not ham radio, which uses frequencies that are nowhere near the 27MHz band. Ham radio allows you to talk to people on the other side of the world, but the signal from a CB radio can barely make it to the next town.

A typical CB radio setup consists of a transceiver, aerial, and microphone. Most transceivers have a small speaker inside them and also a line-out port for hooking up larger speakers. The transceiver is connected to a short aerial by a length of coaxial cable. Handheld microphones are popular with many CB radio enthusiasts, especially those who like to talk while driving, but others prefer to use a microphone with a stand. Some enthusiasts go as far as using a special CB radio amplifier to boost the range of their signal. It allows them to talk clearly with people who are further away, without being drowned out by static noise or stronger signals.

A CB radio amplifier is a simple device that has a short list of features. The main feature to look for is the power output for each band. Like any amplifier, the amount of heat it generates is also important. If there is a cooling fan on the back, turn it on and check out how much noise it makes. Installation is a simple matter of disconnecting the aerial cable from the transceiver and connecting it to the output socket on the amplifier. A short length of coaxial cable, known as a jumper cable, is then connected between the transceiver and the input socket on the amplifier. A standing-wave meter can then be used to check the performance of the setup.

Many enthusiasts prefer to build their CB radio amplifier from a kit. It can be very satisfying to build something as complex as an amplifier from scratch, and it provides good training for anyone thinking of a career in electronics. Assembling a kit is moderately easy for someone who has a basic knowledge of electronics and can read a circuit diagram. The kits are available from specialist stores that sell electronic components and they can also be found on the internet. However, you may not even be allowed to buy a kit in countries where it is illegal to buy a CB radio amplifier.

It is important to understand the laws relating to owning and operating a CB radio amplifier if you want to stay out of trouble. In some countries, it is only illegal to sell or use one but other countries have a total ban. The laws are meant to prevent the airways from being dominated by a few operators with very powerful transmitters. The penalties for breaking the law are severe but few people are ever prosecuted due to the difficulty of catching someone in the act. Most CB radio enthusiasts are responsible enough not to cause trouble and draw attention to themselves, so they get away with using a CB radio amplifier without ever being caught.
