Citizens Band (CB) radios have been a popular means of communication for decades. CB radios are widely used in the trucking industry, off-roading, and among hobbyists. To ensure that your CB radio works optimally, you must maintain your CB antenna. Here are some tips and tricks for maintaining your CB aerial to ensure longevity.

Inspect the Antenna Regularly


Regular inspection of your CB feeler and its mount is critical to ensuring the antenna’s longevity. Check the antenna’s connection to the mount and ensure that it’s tight. Check for signs of wear and tear on both the aerial and the mount, such as rust, cracks, or dents, as these can affect the feeler’s performance. If you notice any damage to the aerial or the CB antenna mounts, replace them immediately to avoid any potential risks or damage.

Clean the Antenna

Dirt and grime can accumulate on your CB antenna over time, which can affect its performance. To maintain your CB aerial, you must clean it regularly. Use a soft-bristled brush and water to clean the aerial. Do not use abrasive materials, as they can scratch the feeler surface. Dry the aerial thoroughly with a clean cloth to prevent water spots.

Protect the Antenna


To protect your CB aerial, you must store it correctly. When not in use, remove the antenna from the mount and store it in a dry, safe place. Ensure that the aerial is not exposed to extreme temperatures, which can damage it. Additionally, protect the feeler from physical damage by avoiding hitting it against objects.

Check the SWR

Standing Wave Ratio (SWR) is an essential measurement for your CB aerial performance. An SWR meter measures the antenna’s efficiency and how well it’s transmitting signals. A high SWR reading can indicate that the aerial is not working correctly or that there’s a problem with the feeler connection. Check the SWR of your CB aerial regularly to ensure optimal performance.

Adjust the Antenna’s Length


The length of your CB antenna is essential to its performance. The antenna’s length is determined by the frequency of your radio. To ensure optimal performance, adjust the aerial length according to your radio’s frequency. A shorter aerial is suitable for high frequencies, while a longer feeler is suitable for low frequencies. Adjust the aerial length until you achieve the best SWR reading.

Use a Surge Protector

A surge protector is an essential accessory for your CB feeler. A surge protector protects your CB radio from power surges and lightning strikes, which can damage the radio’s electronic components. Installing a surge protector can prolong your CB radio’s life.



In conclusion, maintaining your CB antenna is crucial to ensure optimal performance and longevity. Inspect the aerial regularly, clean it, protect it, and check the SWR to ensure that it’s working correctly. Additionally, adjust the feeler’s length according to your radio’s frequency and install a surge protector to protect your CB radio from power surges and lightning strikes. By following these tips and tricks, you can ensure that your CB aerial last for many years, providing you with reliable communication.
