I've seen a lot of people posting about Cobra detectors being mounted improperly so I started looking around. I went to Olive Garden for dinner with my wife the other day, it was kind of busy so I parked a ways away. While walking in I noticed quite a few cars with detectors so I observed the mounts. Most of them were pretty bad. One mounted too low, where the wiper blades would interfere with it. One was angled down too sharply. One was mounted very far front and center on the dash, so as that it was angled down, but while not obstructed it would have done much better to be mounted further back, where it would have been higher up and had a cleaner road view.
There were a couple of others, but only one, mounted in the center of the windshield midway up would have been acceptable. Obviously manufacturers should be clear about this in the manual (I mean even RMR had the proper mounting instructions in the RMR C475 manual, perhaps people aren't reading them, I'd guess if I mounted that RMR according to instructions then put my V1 facing down on the dash towards the wiper blades they'd have performed about the same).
Since I'm curious to see how much this impacts preformance, I'm going to do a few tests with my V1 on some known radar signs tomorrow. I'll mount it up high, down low, and angle it too much and see just what this does for range. Most of the radar signs are along the Thruway where they usually use laser, I have Blinders and am not at much risk (I'll refrain from going too fast regardless). If it hurts my V1, it will certainly hurt less sensitive detectors even more.
