Fixed mount CB radios are installed in trucks, cars and off road vehicles for short range communication on the citizens band, used by truck drivers, off road groups and convoys. The first decision is how much installation you want to do, because compact radios with controls in the microphone fit tight cabs, while full size radios offer more controls and features.
Features are the next question. Weather channels and alerts, noise reduction, adjustable squelch, channel scanning and a public address output are common. Some radios offer single sideband operation for longer range on certain channels. Among the 9 products that list weight, most fall between 1.6 and 4.1 pounds, and 2.3 pounds is typical.
The antenna matters as much as the radio. A good antenna, properly mounted and tuned, has a bigger effect on range than the radio itself. Plan for an antenna mount, coax cable and a meter to tune it.
Handheld CB radios are an alternative for people who move between vehicles, but fixed mount radios with an external antenna reach much further. Check the cable route and mounting location before drilling, and run the power lead directly to the battery with an inline fuse for clean power and less noise. A noise canceling microphone helps in loud cabs.
Before buying, check the radio size, the controls, the features, the power connection, the included microphone and bracket, and local rules on power and licensing. Mount the radio where it does not distract from driving.
