The Complete Guide to CB Radio Antennas

CB radios are a form of two-way radio that allows users to communicate across short distances. CB radios are available in many different forms, styles and functions to cater for the difference in individual differences, tastes, requirements and preferences.

Whist modern technological advancements have paved the way for similar methods of communication; CB radios are still popular and widely used in many countries across the world today.

The purpose of this guide is to inform the reader all about CB radio antennas and to explain how to purchase them safely, securely and efficiently from eBay.

CB Radio

CB or “Citizen’s Band” radio is a system of short-distance radio communications between individuals on channels within the 27 MHz (megahertz) band. Typically, there are 40 channels to choose from within this bandwidth.

CB radio may be used for personal and business communications and owners do not require a licence to use the system. Citizen Band’s channels are the form of a two-way radio service, however only one station may transmit at any given time; other stations must listen and wait for the shared channel to become available.

Whilst modern technological developments such as mobile phones have reduced their appeal, CB radios are still very practical and are popular in many countries (including Australia) in modern times.

CB radios typically consist of:

· An automatic noise limiter or blanker (to reduce background noise)

· ALC (Automatic Level Control)

· CB/WX switch

· PA (Public Address) System 

· RF (Radio Frequency) gain

· Pre-set channels for emergency services

· Volume control

· SWR (Standing Wave Ratio) meter to monitor reflected power caused by incorrect antennas and antenna cables

CB Radio Microphones

There is an extensive range of microphones to choose from to work in conjunction with CB radios. Microphone choices typically include (but aren’t limited to):

· Ceramic microphone

· Dynamic microphone

· Echo microphone

· Electret microphone

· Noise-cancellation microphone

· Power microphone

CB Radio Antennas

The frequency of 27 MHz is a fairly long wavelength used in mobile communications and the choice of antenna has a significant impact on the performance of a CB radio. In general, there are three types of antennas used with CB radios:

The Quarter-Wave Vertical Whip Antenna

This is the most common antenna used with CB radios. The quarter-wave vertical whip antenna is about nine feet (2.7m) tall and it is mounted low onto the vehicles body. These antennae typically have a spring-and-ball mount to offer added flexibility when passing through or under overhead objects.

Co-Phased Antennas

Co-phased antennas are another type of CB radio antenna that is mounted to the vehicles wing mirrors. Using two antennas generally provides a better CB radio performance than using a single antenna- however the performance is only enhanced when the two antennas are spaced at least eight feet apart from each other. Due to the nature of their size and space requirements, co-phased antennas are popular with truckers and long distance drivers who have the necessary space needed to host two separate antennas.

The Continuously-Loaded Half-Wave Antenna

The final antenna type suitable for CB radio use is the continuously-loaded half-wave antenna. This antenna type is often used on fiberglass vehicles such as boats and snowmobiles as well as in base stations. Handheld CB radios often feature a continuously-loaded antenna or a telescoping centre-loaded whip.

Whilst shorter antennas are available for CB radios, the perfect antenna is 8.5 feet, because it is equal to ¼ of a wavelength.
