Here's something to ponder. I've read a few posts recently with reference to certain mounting positions resulting in the detector vibrating from the road and/or strong bass from the stereo. I personally saw some pretty crazy vibrations from the Cobra I was playing with a few months ago. (Anywhere from 1-4mm of travel at the display end.) Clearly this isn't going to be good for the electronics. Additionaly I'm wondering if the motion of the antenna affects it's ability to receive incoming signals. Thoughts?
