The Cobra 29 LTD is a standard 4 W, 40-channel CB radio; it works with a properly installed CB antenna. Vehicle metal, mount location, coax condition and SWR tuning determine the usable system—not an advertised range figure.

Buying tips
- Use a CB antenna, mount and coax system rated for the application; the 29 LTD’s 4W output does not require a high-power antenna rating.
- Mounting position and a sound vehicle ground plane matter. Follow the antenna maker’s instructions; use an NGP kit only for the installation it specifies.
- Route coax without crushing, sharp bends or loose connectors, then tune and recheck SWR after the antenna reaches its final vehicle location.
- The 29 LTD has SWR calibration and an antenna warning indicator; stop transmitting and diagnose high SWR rather than trimming or changing parts blindly.
