I don't have a pic of it, but I can describe it. I was driving down the highway and got a KA alert on my V1 then followed by a J out. I looked around and saw a guy in a minvan with a RD on his windshield. It was mounted in the center of the windshield, but pointing about 30 degrees off axis to his left and about 20 degrees above horizontial. The interesting part was that his RD had some sort of antenna sicking out the right side of it. It kinda looked like the antanna on my wireless router. Anyone know what kind it is and what the antenna is used for?
