How to Buy a Fiberglass Antenna for CB Radio

Below are some of the important things you should look for in a Fiberglass CB radio antenna:


Fiberglass is among the top heavy-duty antenna options on the market. Their construction allows them to flex more than regular antennas, allowing them to withstand abuse force.

These antennas are resistant to wind, making them a desirable option.

Tunable tip

Tuning antennas for optimal reception is not easy. It may require shortening length for the best performance. However, the modern fiberglass antennas are factory-tuned or have a bare-hands tunable tip. It simplifies the process and makes it easier to adjust.

Durability and resilience

As mentioned above, the tough construction and flex make them a top choice. When spending money on CB antennas, a top priority is finding a product that lasts longer.

Fortunately, fiberglass CB antennas fit the category perfectly. The fiberglass rod is quite durable and can withstand off-road abuse.

Best of all, they even withstand overhead obstructions. However, once they crack, they usually break. It makes it all the more important to opt for a well-constructed and high-quality antenna.


Many CB antennas are temporarily mounted on to roofs or are put together with adhesives. However, they tend to degrade over time.

It has brought around the need for more permanent and solid-mounts. They are mounted using drilling holes or installing on bumpers, stake-holes, and tool-box. It helps the antenna last longer and keeps it well-set.

When purchasing this type of antenna, make sure to look for the coil type and have a mounting location in mind.


Are fiberglass CB antennas good?

Fiberglass CB antennas are very good option if you are looking for a long term CB antenna. These are durable, strong, and flexible, making them a great choice for 4×4 and off-roading vehicles.

However, it may not be the best choice for you if you do not want to alter your vehicle or drill holes.

How to tune fiberglass CB antenna?

All antennas need some tuning or adjustment for the ideal SWR. The tuning may appear slightly challenging and complicated for newbies and amateurs. In such a case, we recommend modern antennas with a tunable tip or whip.

It can help to simplify the process. However, older antennas must be cut or shortened for tuning.

Tuning the SWR of the antenna requires clipping the wire to the perfect size. For a convenient experience, we recommend the Firestik FS antenna, with its easy-to-adjust tuning screw in the tip.

How to fix fraying fiberglass CB antenna?

A common problem that a few drivers face is the fraying of fiberglass antennas. However, if faced with this issue, you can easily resolve it at home.

Wash the antenna with soapy water, and allow it to dry. Next, paint the antenna with polyurethane or lead-free, paint. Make sure the paint of non-metallic.

Lastly, sand the surface lightly with 400-grit sandpaper.

How to mount fiberglass CB antenna?

So, what’s the ideal mounting location for your CB antenna? Well, the answer to this question depends on a number of factors.

  1. For the best reception, it’s crucial that the antenna coil is above the roofline. The top of the antenna needs to clear the vehicle’s roof.
  2. A popular mounting option with these antennas is the toolbox. To mount on the toolbox, most drivers and CB radio users opt for the traditional 3-way mount.
  3. If you want to mount it behind the cabin and not the toolbox, the stake-hole can be a great option. Choosing special antenna mounts will mean that no drilling is required!
  4. These antennas have a universal 3/8″ x 24 thread that easily connects to any of the CB antenna mounts. You can use it to mount the antenna on the hood, toolbox, stake-hole, or bumper.
How to shorten fiberglass CB antenna?

A higher SWR on channel 40 than that on channel 1 indicates that your antenna is too long. The problem can be resolved by reducing the height or conductor length of it. They can be cut shorter with a hacksaw or grinder.

Remove the cap and cut the top at ¼ inch at most. Test the SWR and adjust accordingly.

How to tell what kind of fiberglass CB antenna I have?

Wires are wound by wrapping them close together; forming a coil. It helps mimic the performance of a longer length whip on a shorter CB antenna. This “coil” is usually concentrated in a specific area – at the bottom, middle or top.

  • Base-loaded antennas have this coil at the bottom or at the base.
  • With center loaded antennas, there is typically a plastic housing, which stores the coil. It sits above a stainless steel shaft, while the remaining top contains the antenna whip.
  • The top-loaded coils tend to be made of fiberglass. They utilize a thin wire, wrapped along the antenna’s exterior shaft, covered in a protective layer. The coil on these antennas remains above the roofline.


Identifying the type of antenna for your vehicle and specific needs is not always easy. However, with plenty of information at hand, the process becomes simplified.
