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 December 16, 2022
Reviewer: Bryan M from Grand Forks, ND United States  
So far it performs well.  I have a beltronics STIr mounted in vehicle and bought R4 to swap into other cars. When both were on the R4 detector went off well ahead of the Beltronics one. It detected one speed trap miles ahead over a couple hills. False alarms from K band passing cars were similar. The GPS works perfectly and warned of traffic cameras even when pulled down and sitting on the console.

4 of 5 New Purchase Uniden R4 vs R3 December 16, 2022
Reviewer: Mark Buday from Easton, PA United States  
Had to purchase a new Radar unit by Uniden from RadarBusters after my R3 stopped any audible sound (I believe due to bad speaker going?).  Anyway made my choice of the newer R4 for the price.  However, the big negative for me was the audible alert sound is NOT as high as the R3.  Like a 20% drop in the sound.  I always depend on the sound to alert me as the unit is too far away from me driving from the windshield.  I can NEVER read the color bar from where I sit so having this newer version - R4, have a drop in audible sound does NOT make me happy.
I the positive, the unit seems to be noticeably quiter (in terms of false alerts).  I still drive on the same highways and roads daily, so I feel my experiences and input are valid with the R4.
I don't know the Uniden R4 unit like one of the radar geeks and only use the basics to avoid tickets. If I had the disposable money to spend, I would have gone with the Uniden R7.
Time will tell if I am happy with the R4 over the R3 unit.
