They are not suited for use on non-metallic (composite) vehicles or those with insufficient metal. Ground plane dependent antennas require a metallic counterpoise to perform properly. Standard antennas should not be used for applications that do not have an adequate ground plane. If, however, the antenna is mounted in the back, the signal toward the front will be more efficient than those toward the back due to the larger ground plane. If the antenna is in the center of the roof, the signal goes out equally in all directions. The signal is transmitted downward from the antenna, then it hits the ground plane and radiates outward. If your antenna is mounted on a metal roof, the entire roof surface provides a ground plane, assuming that you don't have a sunroof. Standard CB antennas are antennas that require a ground plane (a metallic counterpoise) to perform properly. Ground plane is important to signal propagation for standard CB antennas. There is also a difference between a standard antenna versus a NGP (No Ground Plane) antenna! Please read the section below for a more detailed explanation. They need to be mounted very high, but can handle high power. The best CB base antennas are much taller fiberglass or aluminum antennas (12-18 feet), and they are used for base stations in fixed locations rather than mobile CB operations. They need to be mounted higher on the vehicle and aren't as efficient as top loaded antennas. That's common for professional drivers and magnetic antennas. Whip antennas are base or center loaded antennas topped with a long steel whip that can be tied down when not in use. While fiberglass antennas are cheaper, their advantage is that they can be mounted lower on the vehicle than other types. Most antennas are fiberglass antennas, which are fiberglass poles wrapped with a copper wire and coated with a protective material. There are three general types of CB antennas: fiberglass antennas, whip antennas, and base station antennas. Understanding the Types of CB Antennas Before Choosing the Best These antennas with high wattage power ratings are typically used for CB radios that have been modified to output more power than legally allowed by the FCC, for CB radios that have an amplifier attached to output more wattage allowed by the FCC, or for 10 meter radios (these are not CB radios). Even CB radios with SSB have only 12 watts. Many people beleive that if they purchase a 10,000 watt antenna, it will make their 4 watt CB radio perform better. Please note that we just wrote that all CB radios should not be pushing out more than 4 watts. You need to make sure that the antenna you select can handle the wattage that your radio is pushing out. This rating tells you how much wattage the antenna can handle. While shopping for a CB antenna, you will notice that there are several different wattage ratings. Suggestions for how to choose a CB antenna for your needs are discussed by equipment type below. We can tell you this upfront-the most popular wire-wound CB radio antenna, and our best selling CB radio antenna, is the easy to tune Firestik antenna. That being said, some brands are better and more popular than others. ![]() The best CB antenna for you is the one that best suits your needs and the type of vehicle that you're putting it on. ![]() If you want to maximize the distance that you're able to transmit and receive (and that's the point, to communicate, right?), you'll need to pay attention to the brand and type of antenna that you buy, how tall it is, and where and how you mount it. Prices for antennas are affordable, so buying the best CB radio antenna won't set you back much more than if you buy a cheap antenna. The way that you can stand out is to get the best CB antenna that you can afford. The antenna is the most important component of your CB system.ĬB radios, even the best CB radio on the market, come standard with only 4 watts of power, which is a great equalizer.
