CB or citizen band radios are a highly popular commodity in society. Distances and clarity are often key elements when using CB radios, which makes the antenna an important factor. Many companies that have a large workplace or employees in extended locations use this method of communication. Also, truck drivers often communicate with one another via CB radio. Therefore, it is obvious that a consistent and clear transmission is required. Obtaining this clarity partially depends on the capability of the radio itself; however, even more importantly is the role that the antenna plays. Although CB radios are not intended to be used over extremely long distances an ample antenna is essential for communication and may vary with respect to its environment and type of radio.
There are a variety of antennas that are used with CB radios. Some are long while others are shorter. The shorter ones usually incorporate coils to extend reception without extending the height of the antenna. Most car and small truck mounted antennas are a whip-like style and approximately 9 feet in length. These are supported by a spring like mechanism to accommodate for wind and other hazards. These are sturdy yet flexible. Consumers please note that car and truck antennas should be properly grounded to ensure safety. Handheld CB radios use antennas that are strong yet small and are omni directional. Boats usually use continuously loaded half wave antennas. This proves to be most effective with the boat's make-up and water environment. Some radios even use multiple antennas. There are consumers that use longer antennas than those mentioned and attach amplifies to increase signal strength. These are usually illegal; however, many are commonly used.
Since a CB antenna plays such an essential role, it only follows that one should make sure it is the best antenna for the job. CB radio antennas both receive and transmit waves. They receive a wave and convert it while sending it to the receiver. The opposite is done when transmitting. The efficiency is determined by the impedance and can be measured by using a meter to determine the SWR. This will tell you if the antenna is performing well or not.
Overall, if you are purchasing a CB radio or already own one, consider the antenna because it plays an instrumental role. How clear and how far one can communicate is directly correlated with the antennas ability. CB radio antennas are designed for different waves, lengths, and wattages. Some are even rated up to the 1000 watt range. Wilson, Francis, and Firestik are popular brands.
