MB3B CB radio description
Retevis MB3B CB radio kit is a compact mobile CB radio with AM/FM modes, 40 channels, NOAA weather alerts and NRC digital noise reduction for transmit and receive. RF gain picks up faint signals, while SWR protection assists antenna placement and monitoring.
The small chassis fits tight cabs and runs on 12V or 24V through a cigarette lighter plug, including full-size pickups and heavy trucks. A 3.5 mm PA interface connects an external speaker, and one-touch emergency channel access is included.
