The R4 replaces the R3, which is one of the most well-regarded designs of all time. The new design features larger top buttons and a dual low-noise amplifier design to improve range. A colorful OLED display provides information about the type of radar signal that is being detected and the strength of the signal to give you an idea of how far away it is.

Range

Uniden claims the R4 has ‘Extreme Range.’ Independent testing by VOrtex Radar indicates that the R4 has a range of around 2,250 feet in real time use. That is enough distance to typically provide you with 30 seconds or more before you reach a threat.

False Alert Filtering

The R4 has advanced false alert filtering technology that helps avoid signals from unnecessary sources, like Advanced Drivers Alert Systems and things like automatic doors. In theory, the R4 logs and eliminates signals that it recognizes automatically. You can also manually set lockout spots to eliminate false signals in areas that you regularly drive through.

The R4 has built-in GPS that the devices use to remember locations where false alerts happen so they can automatically be silenced, preventing you from having to be alarmed for no reason.

Pros

  • Better than anticipated range, even under adverse situations
  • Very good false alert filtering system that prevents unnecessary alerts

Cons

  • Lacks directional arrows to determine the location of threats
  • Only detects signals from one direction

Alerts You Can Use

The R4 provides alerts using both tones and voice alerts. This way, you can get the warning you need in the best way possible for you. The Uniden R4 takes advantage of Quiet Ride Mode that takes advantage of the false alert filtering and GPS technology to keep it quiet when you are driving.

What it is Like to Use

UNIDEN R4 in the box

The Uniden R4 is a mid-range option that includes some of the best high-end features available. In practice, this is a great detector that offers relatively fast detection speeds and a good range that will give drivers plenty of time to react. The dedicated low-noise amplifier for the Ka band ensures that the device is accurate and detects radar signals at a very long range.

Overall, this is one of the most user-friendly radar detectors around and offers impressive range and functions.

Conclusion

The Uniden R4 is an excellent upgrade from the Uniden R3. (Check our full comparison) It offers excellent range and several design features that make the R4 more user friendly. In particular, the larger buttons and presence of a front mute button are nice touches that make it work well (>>> Find the current price on Amazon).

One thing that we particularly like about the R4 is the Quiet Mode. It actually works very well to prevent unnecessary alerts and does a better-than-expected job of reducing false alerts. In practice, you can almost forget that the device is in the car until you need it.

Like the R7 and R8, the R4 auto lockout feature doesn’t work very well. Most of the time, the lockout only works when you are very close to the signal. Even then, it will often fail to log the lockout or will not silence the alert.

A radar detector offers you a layer of security that helps prevent you from getting unnecessary speeding tickets. The reasonable cost of the R4 along with its proven and reliable performance make it one of the best options on the market today.
