Not so good 34.7Ka range when shot from the rear. I actually got pretty good 34.7Ka alert at the bottom of the long and steep freeway ramp. I started recording when I saw the UHP at the top of the ramp. It's possible that the UHP turned the radar off toward the end of the video, but not likely in this case. To be fair, I've seen some decent 1/2 mile to 1 mile forward facing 34.7Ka detections on I-15 before. A Valentine 1 would be nice to have if you are ever shot from the behind, because of it's rear facing antenna.
