How to Buy the Best CB for 18-Wheeler

Benefits of CB Radios

  • Cost – the technology used to make CB radios has not changed since early in the 1940s. Thus, it's highly affordable that most technology types are used for communication. Plus, you can get CB radios on the market and with convenient functions.
  • Size – back in the nineteen seventies, CB radios used to take up lots of space on dashboards, inconveniencing. Thanks to several advancements in technology, these resources are nowadays small and portable.
  • Licensing – using CB radios does not require any form of licensing compared to the likes of ham radios, General Mobile Radio Services, and more. Usually, most CB antenna brands make products that adhere to the Federal Communications Commission regulations (FCC). 
  • Features – similar to most communication and electronic tools, CB antennas have evolved over the past few years. However, these tools also have various functions that help improve the mic and range of the antenna's performance.
  • Community – quite contrary to what you may think, community does not refer to the conventional social media platforms in this case. On the contrary, it refers to CB radio social media groups, where they gather and conduct discussions.


Size is a crucial factor to consider when you want to get the ideal antenna. When it comes to antennas, the school of thought is that the size is directly proportional to the antenna's performance. That said, not many people would want a 10-foot antenna on the roof of a car.

Learn how to make a compromise if you want to get the right antenna for your truck driving tasks. The tradeoff has to be between the size and expected performance of the antenna. 


The ideal CB radio antennas should be durable and provide longevity, especially as you will be traveling and using it a lot. The most durable types are the types that are made using fiberglass material for longevity. These types work best in various situations and are less likely to get snagged by issues such as trees. 

In this category, we recommend the Cobra HG A1000 because it's known to last for many years without any issues. 

Frequency Bandwidth

It’s a term that refers to the frequency range that your chosen antenna can cover. Usually, antennas can cover between 26-28Mhz. That said, some differ in terms of the frequency bandwidth ranges. It's best to go for frequencies that you will be using regularly.

Power Handling

The ideal CB antenna should be able to handle more than a 4-watt output to make communications convenient. Ensure the antenna can also accommodate the amount of output the CB radio can produce to avoid damaging the internal components.

Questions to Ask Before Buying a CB Antenna? 

Ask yourself these few key questions before you invest in a CB radio for communication purposes. They include:

What is the right location for mounting?

Depending on the type of your chosen CB antenna, you can mount it on the bumper, mirror bar, or the roof of the car. Various factors come into play at this point, including the radio's functions and the way you plan on using the mounting system. The most crucial factor would be to install the antenna at an elevated section for the best reception. Remember to keep the antenna grounded to the chassis of the car for stability. 

What is the length of the antenna?

The length of the antenna is directly proportional to its performance. Users require long antennas, especially if you have to drive through areas with low signal quality. Plus, you will come across various accessories that you can use to set up the radio. The length should be suitable for use even if you want to access poorly spaced parking areas.

What is the type of coil?

We can classify antennas based on the site and the positioning of the coil. Since such a tool's function varies due to its length, ensure you consider the length thoroughly. Plus, a coiled wire is ideal because it makes it easy for users to adjust the antenna length. It’s a component that lets you customize the antenna to suit spaces that are cramped up for space. That said, reducing the length of an antenna can have adverse side effects on its efficiency.
