Product Details

The Texas Ranger TRE Top One is a compact CB radio that’s perfect for fitting into the dashboard or overhead console of your truck. You can transmit in AM, LSB, or USB mode and fine-tune the sound with its variable bass/treble control.

The display, with its bright white LEDs, shows the channel and frequency, and you can adjust the brightness to your liking with the dimmer control. Plus, the touch-select multi-color backlight bezel lets you personalize the display color. With a built-in SWR meter and high SWR alert, you’ll be warned of any antenna issues. The front-mounted microphone makes it convenient to use.
