Key Features
40‑channel CB coverage for standard U.S. CB operation, giving access to common road and convoy channels.
Compact mobile form factor that fits easily in small cabs, dash cubbies or under‑dash mounts.
Illuminated display and controls for clear visibility of channel, TX/RX status and key functions at night.
Automatic Squelch Control (ASC) plus manual squelch, helping keep the speaker quiet until a real signal is present.
Noise reduction features such as ANL, NB and hi‑cut audio to reduce engine noise and background hiss.
Quick emergency / priority channel access so you can jump to key highway channels with one button press.
External speaker and PA support (on many variants) to drive a louder external speaker or PA horn in noisy environments.
Rugged microphone with channel buttons for convenient up/down channel changes without reaching for the front panel.
Benefits
- Improves safety and situational awareness that easy access to CB traffic, weather and hazard reports lets you react sooner on highways and backroads.
- Reduces noise and fatigue on long drives that automatic squelch and audio filters cut static so you hear important conversations more clearly.
- Fits where bigger radios won’t, where small housing makes it ideal for compact interiors, dash pods or shared vehicles.
- Easy to use for new CB operators that clear labeling and simple controls mean drivers can get on the air quickly with minimal learning curve.
- Versatile for work and play that is suitable for commercial fleets, RVs and off‑road clubs alike, giving you a reliable communication tool in many scenarios.
