The Uniden R4 is one of two new Uniden radar detectors, having even higher performance than the Uniden R3, the other new radar detector, is the dual-arrow Uniden R8.

Having more than 14-times the capture distance of a police radar gun, the Uniden R4 provides performance often exceeding all other manufacturers' top performing detectors at considerably less money and is currently the most sensitive single antenna detector we've ever tested!

The result is that the Uniden R4 will provide you with more than ample warning of instant on K and Ka band miles away.

Filtering

One of the main benefits of the Uniden R4 is that it now incorporates an LNA for Ka-band as well as an LNA for X-band and K-band for about a 3dB increase in sensitivity over the Uniden R3.

5 of 5 Uniden R4 Rocks ! June 14, 2022
Reviewer: JohnnyWalker from Falconer, NY United States  
after using the R4 for a few weeks, I can say it is a great detector. It does all exceptionally on picking up KA signals and filters K signals well. Some vehicles safety systems alert (I think) occasionally, but is a very quiet detector. Range is exceptional, even off axis and far away. I have yet to get a laser signal. I wish I had not waited to order it RadarBusters shipping was fast and flawlwss.

5 of 5 Great service February 28, 2022
Reviewer: Hugo M. from San Francisco, CA United States  
The R4 is a great upgrade from the R3. It already saved me today when a car behind me got pulled over by a CHP as the R4 gave me ample warning
