Best CB Antennas for Semi Truck & 18-Wheeler

Different types of antenna for semi-trucks

Have you ever watched the 1975 movie “Convoy“? If you did, you would have seen the heavy use of CB in that movie. Well, the film was set during the heyday of the CB usage sometime in the 70s. Although CB has already lost much of its original appeal, it is still popular among truckers. So, if you are one of those truckers who are spending time trying to figure out which CB antenna for your 18-wheelers/trucks is the best, you better read on through this article.

The CB is useful for short-distance person-to-person communication between two persons. It usually operates on 40 channels in the shortwave band and is very useful.

Even if you have an expensive CB radio, your CB’s efficiency is determined by your CB’s antenna. But with myriads of antennas in the market today, you may end up confused about which antenna to purchase for your truck. So, it will help if you know the different types of CB antennas and the most recommended models and brands in the market today.

As mentioned above, selecting the right CB antenna for your semi-truck/18-wheelers may prove to be difficult if you are new to buying this thing. The reason behind this is evident—they come in different types and brands. Hence, to help you in buying the best CB for your need, I have listed here the five popular types of antennas in the market today:

1) Fiberglass CB Antenna

If you want a durable CB antenna, you should check the fiberglass CB antenna. Fiberglass CB antenna, of course, stays intact for a very long time. Moreover, it is made of a fiberglass rod and is a perfect choice for larger vehicles. You can also mount the fiberglass antenna almost anywhere, even on hood channels, stake-holes, and mirror arms. Its range, however, is not top-notch as compared to other types of antenna. 

These antennas are quite flexible and come with a universal thread to connect to any CB antenna mount quickly. If you intend to install this on the fender or bumper, you should choose a top-loaded antenna for excellent transmission. Besides, a three-foot antenna mounted on the fender will work perfectly well with most semi-trucks.

2) Magnet Mount CB Antenna

If you want an excellent CB antenna when it comes to ease of mounting, you should consider the magnetic CB antenna. It grabs firmly on the surface. It gets its ground from the magnet that attaches to the car body. This type of antennas comes with a straightforward installation process, which makes it very popular among many. This may not be the best ground connection to the car’s body, and the magnet’s size usually determines the firmness of the antenna’s grounding. It’s normally installed with the magnet mount, coax and whip in a set.

3) 102" Whip CB Antenna

The 102″ Whip CB Antenna separates itself from other antennas because it does away with the use of a coil. It does away with the usual coil because it can transition to a perfect 1/4 CB wavelength. A whip antenna consists of a rod or a straight flexible wire, and its bottom end connects to the radio transmitter or receiver. 

The antenna is flexible and doesn’t break easily. Moreover, its name came from its whip-like motion when agitated or disturbed. It also has an omnidirectional radiation pattern.

4) Center-load CB Antenna

If you are a trucker, you might as well consider the Center-load CB antenna because it is called a trucker antenna. The usual center-load antenna comes with a stainless-steel shaft about a third of the antenna’s length. On the other hand, the coil sits above this shaft and is encased in a plastic housing. 

This Center-load CB antenna sports a thin whip feature made of steel. This type of antenna, of course, performs excellently, compared to similar mounted types of antenna. Yet, this type of antenna is more pricey than the other types of antennas.

5) No-ground Plan (NGP) CB Antenna

If your vehicle is mostly made of fiberglass, plastic, or wood, you should consider the NGP CB antenna. The No-ground Plan (NGP) CB Antenna is engineered explicitly for solving problems that come with the lack of counterpoise or ground plane. 

Problems associated with ground plane include low performance and high standing wave ratio (SWR). Thus, the NGP CB antenna came to remedy these problems. It eliminates problems due to a lack of sufficient ground plane for the right operation. You can use the NGP antenna on any vehicle that does not come with metallic chassis.
