  • Our take on the 18.5 inch Magnetic Mount CB Antenna

    This is a short 18.5-inch magnetic-mount CB antenna with a black stainless steel whip, a 4-inch magnet base and a 15-foot braided coax cable ending in an SO-239 connector. It covers 26-30 MHz at 100 watts, so it handles standard 4-watt CB radios and receives NOAA weather channels. The small size makes it easy to move between vehicles and store, but a short whip trades range for convenience, and owners say a longer antenna reaches farther. It suits casual CB users, daily drivers and anyone who wants a quick, removable setup rather than maximum distance.

    Questions and answers

    Will this work with any CB radio?
    It uses an SO-239 connector, the standard CB fitting, and handles up to 100 watts, so it works with typical 4-watt CB radios. Check that your radio's antenna socket matches.
    Does it receive weather channels?
    Yes. It covers 26-30 MHz, which includes the NOAA weather channels on a CB radio that supports them.
    How well does the magnet hold at highway speed?
    The 4-inch magnet base is meant for roof or trunk mounting and is easy to reposition. Clean the paint surface first, and route the coax so it does not pull on the base.
    Is a short antenna good enough for highway range?
    It is fine for nearby traffic and daily driving, but a longer whip generally reaches farther. Buy this one for convenience and clearance, not maximum distance.
    Can I move it between vehicles?
    Yes. The magnet mount and 15-foot cable let you lift it off one vehicle and set it on another in minutes.
