CB Radio - Most new CB radios come with a microphone, mounting bracket and power cord, so you won’t need to buy those separately. CB Antenna - Without an antenna, your radio is useless! Don’t forget this key component. CB Antenna Mount - You’ll need a mount of some sort to attach the antenna to your vehicle.What is tuning a CB radio?
Tuning a CB radio means fixing the antenna. Sometimes, the antenna will need to be adjusted to get the optimal signal. Most fibreglass antennae have detachable segments at the top to allow for extensions, so antennae can be lengthened that way. Antennae can also be shorted by sawing the antenna down as needed.What is the ideal CB antenna length?
The higher the antenna goes, the farther your message will go, and you can receive messages from farther away. The ideal length antenna for CB radios is 102 inches (about 8 and ½ feet!) because it is equal to ¼ of a wavelength. Obviously, this isn't even an option for most people.
