Things To Look For Before Buying

Shopping for the best magnetic mount CB antenna for the first time? Don’t have a clue where to begin your selection process? Don’t panic. Below, we have outlined some crucial factors to help you easily navigate to the most suitable CB antenna for your unique needs.

Antenna length

One of the things to look for when choosing a magnetic antenna for your CB radio is its overall length. Apart from affecting the quality of the signal, the length of the antenna will also affect the clearance you have over your vehicle. The taller the antenna you get, the better the range boost you’ll get.

As for the clearance, you need to keep in mind where you’ll be riding your vehicle. Is your path characterized by tunnels and under tracks? Where will you be parking your truck? All these will give you a clue on the ideal length of the antenna to buy.

Power handling capability

Another essential consideration to make when picking a magnetic mount CB antenna is its power handling capabilities. This is because this factor greatly contributes to the clarity of signals your antenna intercepts. The higher the wattage, the better the reception. As much as possible, look for antennas with up to 300 Watts power handling as they tend to offer a remarkable reception.

Construction materials

Yes, you should also check the materials used to construct the antenna you want to buy. The trick here is to go for an antenna designed using materials that stay strong for an extended period of time without showing any signs of damage. The materials should also be weather-resistant since you’ll be hooking the antenna on your truck. Stainless steel is the most preferred material for these CB antennas by the top manufacturers.


We said that magnet CB antennas come as all-in-in packages. This means that they come with a coaxial cable included as well.  For this reason, you’ll need to check the cable quality as it directly affects the antenna performance. Aside from quality, you’ll also need to consider how long cable is. The perfect length will depend on the size of your vehicle. For trucks, 18-wheelers, and other larger vehicles, you’ll need a longer cable.

Magnetic mount

A magnetic CB antenna employs a magnet at its base to be installed on your vehicle. That said, it’s important to check the mount that comes with your antenna. Ensure you get one with a heavy-duty magnet that securely attaches your antenna in place and prevents it from being knocked by winds.

Also, make sure the magnet has a non-abrasive surface to prevent scratching your vehicle paint. Some manufacturers use a rubber base or plastic coating on the mount to prevent it from scratching your vehicle.
