CB Antenna Buying Guide

So, what is the Top CB antenna? If you are still undecided, this section of the article can further help you make an informed buying decision. This portion talks about the available types of CB radio antennas, alongside the buying considerations, and more.

CB Radio Antenna Types

In general, there are two CB radio antenna types, including the base units and the mobile models. Today, the mobile CB radio antennas are the most popular and widely used on vehicles, ranging from cars to trucks, SUVs, RVs, and more.

  • Base Antenna – The base antenna is primarily used with a base CB radio unit, which remains stationary. Since a base CB radio remains stationary, it can use a larger antenna, which also ranges from a stick antenna to a ground plane antenna, a J-pole, a beam antenna, and other kinds.
  • Mobile Antenna – A mobile antenna for a CB radio is generally categorized into two types, including the whip antenna and the hustler twin antenna. The latter has a center-loaded coil, while consisting of two individual antennas that work hand in hand.
    A hustler twin antenna delivers a good signal and is widely used by truckers. On the contrary, the whip antenna is usually made from stainless steel or fiberglass and is most common on regular vehicles.

Buying Considerations

In order to get the best antenna for CB radio, it is very important to take each of the following factors in mind, while shopping for such equipment. Each of the variables plays a crucial role throughout the function and performance of the antenna, while affecting the entire efficiency of the CB radio unit.

  • Mounting Location – Antennas for a CB radio can be mounted on the roof, trunk, bumper, mirror bar, or hood channel of the vehicle. Each of the location has its own pros and cons. So, choosing the affixing location largely depends on the primary use of the CB radio as well as the type of vehicle.

    Keep in mind that the higher the antenna’s location means it will perform better as the coil should sit above the roofline, allowing for optimum performance. It is also important to take note that the antenna should be securely grounded towards the vehicle’s chassis, making the No – Ground Plane antenna the perfect choice, especially for RVs.
  • Mount Size – The antenna’s mount size must be suitable for a specific antenna because the mount secures and attaches the antenna to your vehicle. For instance, a 2-foot antenna can be perfect for a magnetic roof mount, while a large 5-foot antenna requires a more secured mount.
  • Antenna Length – It is believed that a longer antenna works more effectively than a shorter one. As a potential buyer, you can choose between different antenna lengths that will suit your vehicle and personal preferences. In general, the CB antenna length should be practical, considering available accessories like quick disconnection features when you are driving into an underground car park, a low garage, or a drive-through with low head room.
  • Antenna Coil Type – These antennas are also classified according to the coil position, also known as load position. A CB radio antenna works, based on the length in correlation to radio wave, making long ones impractical for most vehicles. Hence, these antennas have been redesigned with coiled wires, enabling the necessary length, while remaining practical. Today, there are three types of antenna coil as explained below.
  • Base Loaded Coil – In a base loaded coil, you will find the coil at the antenna’s base. The majority of all-in-one and magnet mounted antennas, including the roof-mounted models are base loaded. The base loaded CB antenna is very easy to install and mount with a high-watt capability. It is commonly used on trucks and cars, although it said to be less efficient than loaded antennas.
  • Center Loaded Coil – In this particular type, you will find the coil in the antenna’s middle portion. A center-loaded antenna is commonly used on trucks, and is believed to have high watt capability as well. It is considered to be more effective than the base-loaded counterparts.
  • Top Loaded Coil – Meanwhile, a top loaded CB antenna is mostly made from fiberglass and is considered as the most effective of all the available coil types. It is also inexpensive with low watt capacity. It is the most famous coil type and widely used on trucks, RVs, cars, and many other vehicles.
