Is Something Wrong or Does My Radar Detector Suck?
You’re driving down the interstate an a mile down the road you see a trooper with their reds and blues flashing with someone pulled over.
Then when you’re within a quarter of a mile of the officer, your radar detector starts alerting and you start ask, “Is something wrong or does my radar detector suck”?
I can assure you that neither are the case, let me explain.
Police radar guns are directional, meaning that the RF (radio frequency) they transmit travel in one direction.
So in many cases as you approach an officer that has someone pulled over, the antenna of the radar gun is pointed in the opposite direction that you’re traveling, as illustrated in this graphic.
Therefore any RF that you radar detector is detecting until you pass the officer, is the reflected signal ricocheting off of other objects such as signposts, vehicles and other reflective surfaces within the radar signal path.
