Nevertheless, it will help if you know the different types of CB antennas mentioned above and the most recommended CB antennas in the market today.
Buyer’s Guide: Types of CB Antenna
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.
Factors to Consider When Choosing a 18-Wheeler & Semi-Truck’s CB Antenna
However, when it comes to the CB range, several factors may determine it, such as the antenna length, surrounding terrain, quality of the antenna, type of installation, and the ionosphere status. On average, however, the range of CB is between three to six miles, with the upper range at ten miles. In this article, however, we will give you a rundown of the best CB antenna for a semi-truck/18 wheeler truck to facilitate the choosing process for you.
You will have many options when mounting a CB antenna, depending on the antenna type and the reception you would like to have. You can mount the antenna, for example, on the vehicle’s roof, bumper, mirror bars, or even the truck’s trunk. Yet, where you mount it depends more on your preference.
Nevertheless, it’s good to consider that the higher the antenna mounting, the better it can transmit signals. So, it will help if you mount your antenna on a higher part of your truck for better transmission of signals. Moreover, you should maintain the antenna coil above the truck’s roofline to lessen interference.
Another important consideration when choosing a CB antenna is the cable quality. Many CB antennas feature a coax cable. But to ensure that you will have a quality cable for your antenna, it will be best to check the cable quality carefully, for the cable quality can indeed affect the CB signals. Moreover, it will be best to check if the kit you will buy comes with a coax cable long enough for your setup.
The antenna coils are the locations wherein the wire of the antenna winds into a coil. But why is it necessary for the antenna wire to take a coiled form? The reason is simple: the antenna loading coil consists of an inductor that is placed in series along the antenna to lower its resonant frequency.
For a CB antenna, the optimal length of the antenna is 102 inches, for this length represents a wavelength quarter. It is, however, impossible more often to mount an 8.5-foot antenna to a semi-truck. To skirt around this problem, many manufacturers wound or coiled wires tightly along the body of the antenna to compensate for the shorter length of the antenna. So, with the coil, a shorter antenna can work as if it is 102-inch long.
This coil is concentrated on a specific portion of the antenna. It can be at the middle, bottom, or top part. Moreover, this process is more practical and allows for the use of a shorter antenna.
The coiled portion of the antenna is the point wherein the antenna receives and transmits the strongest signals. The coil, however, should be over the roofline to avoid the blocking of the line of signals.
When selecting an antenna, you also must consider the technical aspect of the product carefully. For example, if you are a long-distance truck driver who traverses various states, you might as well go for an antenna that has ready access to weather channels. Weather-related information is crucial to safe travel. You should also go for something compatible with almost all CB frequencies to maximize the use of your antenna.
Nevertheless, if you are a fast driver who drives faster from one place to another, you might as well go for something that is sturdily mounted, like a rigidly mounted magnetic base. If you doubt the capability of the magnet, you can settle for the screw-on method of mounting, which is more traditional but often reliable.
Frequently Asked Questions
If you know the abovementioned most recommended CB antennas for semi-truck and 18-wheelers, you might as well learn about the following frequently asked questions about CB antenna, for they may also be the questions playing in your mind:
How far is the reach of a CB Radio?
The range of a CB radio is from one to fifteen miles between the transmitter and the receiver. Nevertheless, some factors can affect the transmission of signals. Such factors include the length of the antenna, the surrounding terrain, the quality of the antenna, the installation type, and even the ionosphere status. If you transmit between mobile and base, you can get a range of five to ten miles. But between base units, you can expect a range of ten to thirty miles.
How can you install your CB Radio on a Semi-truck?
Installing the CB radio on your semi-truck requires you to follow the user’s manual of the CB radio. Yet, to give you a good idea of how to install your CB radio, you can simply mount the antenna, first, onto the spring. Make sure that the tip doesn’t hinder the roof. Then, mount onto the magnet mount the spring.
Then, connect the coax cable to the read end of the CB radio. Make sure that there are not many wrinkles in the coax wire connection. Afterward, connect the mic to the radio. Gain access to the RED+ wire. Then, clip from your radio the RED= wire. Once connected, locate the metal screw attached to the metal bodyboard of your vehicle. Then, pleat the Black-wire finish onto the bolt.
How would you set the SWR on your CB Radio?
To complete your antenna installation, you need to engage in CB Radio arrangement. You would need to use the SWR meter for this purpose. The SWR meter will enable you to know where you will install your reception apparatus.
The SWR meter can be built-in or a separate unit. If you use a separate SWR meter, you must use a coaxial link jumper to connect it to the CB radio. The jumper usually comes with an AUSWR SWR meter.
How can you lower the SWR on your antenna?
You want to bring to a 1:1 ratio the SWR proportion, for it is the reasonable thing to do. You can also move the antenna to an ideal location to get the right spot for installing it on your truck. To achieve this ratio, park your car in an area that has no blocking features. Then, adjust the meter and test the SWR by squeezing the channel one key and the channel forty key.
If you get a reading that got channel 1 higher than that of channel 40, you can extenuate the reception apparatus by going in for a 1/8″ incremental increase. If it is lower, then start shortening your antenna and engage in a retest.
