Had a really good chance to test the 9500's range last week. Took a 250 mile trip out on the open highway. Took peoples advice and mounted it up high to the left of the RVM. Unfortunately not hard wired at present time, but coming soon.
Several encounters with LEO's, the most impressive being alerted (Ka)on a very long, straight flat section in which the LEO was a virtual dot on the horizon. I estimated the distance to be well over a mile when I was first alerted.
The rear radar antenna has impressive range as well with my estimations being around 3/4 of a mile (Ka).
My question is: at what distance can a LEO w/ Ka accurately measure your speed?
