Before you purchase a CB antenna for your vehicle, it’s important to consider all of your options.

What Is A CB Antenna?

A citizens band, or CB, radio antenna is used in conjunction with a CB radio to transmit and receive radio frequencies.

The antenna captures incoming radio waves which are then converted by the CB radio’s receiver. The receiver also converts outbound electrical signals from the CB radio’s transmitter and broadcasts them out through the antenna as radio waves to hopefully reach another CB radio. This back-and-forth transmission creates communication between CB radios.

CB antennas radiate frequencies of a specific wavelength. A CB antenna that is properly tuned will accurately match the radio frequency’s wavelength it is transmitting. CB frequencies start at 25.01-MHz, with common wavelengths for antennas starting at ⅛, ¼, ½, and ⅝.

What Do I Need To Install A CB Antenna?

In order to install a CB antenna to your vehicle, you will need the following components:

• CB radio: This device converts radio waves into electrical signals for communication and is also known as a ham radio.
• CB antenna mount: This connects the CB antenna to your vehicle. If you recently acquired an antenna that did not come included with a mount, you will need to buy one separately.
• Coaxial cable: This cable connects your antenna to your radio via a PL-259 connector and is also referred to as a coax cable.
• SWR meter: An SWR meter is a device used to adjust your antenna so it is properly tuned. An untuned CB antenna not only performs poorly but can cause permanent damage to your CB radio.

CB Antenna Mounts

There are several common variations when it comes to mounting a CB antenna your vehicle. Choosing the best CB antenna will depend on your vehicle and transmission needs.   

• Magnetic mount: As its name implies, these utilize a magnetic base for mounting. They come with a coax, mount, and whip antenna. Transmission and receiving range vary by where the mount is placed on a vehicle, with antennas ranging between 3.0 and 5.0 in. for 3.0 to 7.0 miles of range. While they perform well and are incredibly easy to install, magnetic mount CB antennas have low clearance due to their long length.
• Center-load: These are commonly called “trucker antennas” because of their frequent use on semi-trucks. They have a thick stainless steel lower shaft with a plastic-cased coil and whip antenna on top. These antennas are generally 4.0 to 5.0 in. long with a range anywhere from 7.0 to 10.0 miles. Although they perform better than most fiberglass and magnet mounts, center-loaded antennas are more expensive and prone to damage.
• Top-loaded antennas: This mount format is good for mobility and usually fairly affordable. Although commonly made of fiberglass and have great functionality for receiving and transmission, top-loaded antennas typically have lower wattage ratings due to using a thinner coil wire.

Types Of CB Antennas

• Fiberglass: These are built from fiberglass rods with the antenna wire wound along the outside and covered with plastic wrap. They typically range in length from 2.0 to 5.0 in. and have a range anywhere between 2.0 to 7.0 miles. Fiberglass antennas are best suited for off-road vehicles due to their durability. They can be mounted nearly anywhere on a vehicle.
• 102” whip: Unlike other antennas, 102” whips don’t have a coil. This is because a 102” whip antenna represents a perfect ¼ CB wavelength, which gives it over 10.0 miles of range. They are usually around 8.0 or 9.0 ft. in length and are relatively inexpensive but require a heavy-duty mount for support.
• No-ground plane (NGP): These are designed for RVs, boats, or any vehicle that doesn’t have a metal chassis. They work without requiring ground for transmission and receiving, but are expensive and have limited range compared to other antennas.

Does A Longer CB Antenna Perform Better Than A Shorter One?

Yes, a longer/taller CB antenna can improve the range it transmits and receives signals. The general rule of thumb is that every inch added to a CB antenna increases its range by 1.0 or 2.0 miles. A true ¼ wavelength CB antenna is frequently cited as having one of the best ranges, yet its 8.5-foot size makes it very impractical. Whip tie-downs can help reduce swaying for these antennas.

Because there are so many factors that can affect radio transmission range, it is almost impossible to guarantee any kind of maximum range for antennas. Do not believe any guarantees you read online, as most reputable manufacturers will know this and will not specify a guaranteed range.

FireStik FireFly CB antennas have a flexible design, making them more wind-resistant than other fiberglass antennas. One of the product’s significant features is its adjustable “bare-hands tunable tip” that makes tuning as easy as popping off the tip and turning the adjustment screw. Its high-performance coil design with double-insulated copper wire also promotes consistently clear transmission and reception.

Fiberglass CB antennas are built for the rigor of off-roading, so we recommend the FireStik FL3-B FireFly for those who like to take their radios out on the trail. It can work just as well for day-to-day use, too.
