5. Performance
Crystal-Clear Communication
With 4 watts of output power — the maximum allowed by law for CB radios — the Cobra 29 LTD delivers excellent transmission clarity. The combination of RF gain and mic gain adjustments lets you fine-tune performance to your exact needs.
Optimized Range Through SWR Calibration
One of the standout features is the built-in SWR (Standing Wave Ratio) calibration system. Proper SWR tuning ensures that your antenna is operating efficiently, giving you better range and less signal loss. This is especially useful for truckers who travel through areas with varying terrain.
Emergency-Ready Functions
Instant access to Channel 9 ensures you can reach help in emergencies, while Channel 19 keeps you connected to the trucking community for traffic and road updates.
Versatility with PA Mode
When paired with an external PA speaker, the Cobra 29 LTD can be used for public announcements — useful for events, off-road gatherings, or guiding vehicles in convoy situations.
