Uniden PC78LTX 40-Channel CB Radio with SWR Meter Silver

CB Radio with 40 Channels

The Uniden PC78LTX is a 40-channel CB radio designed for truckers and mobile users who need reliable voice communication on the road. It includes an integrated SWR meter for antenna tuning, a PA function for external speaker output, Hi Cut noise filtering, and adjustable Mic and RF gain controls. Instant Channel 9 access provides a direct shortcut to the emergency frequency.

Suits drivers who need built-in antenna diagnostics

This radio suits drivers who want to set up and verify their antenna system without carrying a separate meter. The PA function adds utility for addressing people outside the vehicle. Buyers who require single-sideband modulation, weather-alert reception, or Bluetooth connectivity for hands-free operation should look at other models that provide those features.

Integrated SWR meter

The defining specification is the integrated SWR meter, which lets you measure standing-wave ratio directly from the front panel. This allows immediate antenna tuning for maximum transmit efficiency and protects the output stage from high reflected power. If you already own an external meter or prefer a smaller radio without this function, a different unit may be more appropriate.
