The Radio Shack TRC-484 is a classic 40-channel CB radio designed for clear, dependable communication. Its PLL (phase-locked loop) synthesizer uses a precise reference crystal for accurate tuning across all channels, while the digital channel display keeps your selection easy to read at a glance.

Cut background noise with the squelch circuit, tame overly strong signals using RF Gain, and check status with TX/RX indicators. A front-panel channel selector plus mic Up/Down buttons make quick changes simple. For safety and traffic info, an emergency switch jumps straight to Channel 9 or 19. The radio also includes an external speaker jack, a PA speaker jack, and a universal mounting bracket for clean installs in trucks, SUVs, and small base stations.
