Abstract
A remotely mounted radar detector is mounted vertically behind a license plate with a reflector attached to the horn at an angle such that the reflector extends beyond one edge of the license plate to reflect incoming, horizontal radar signals into a vertically oriented plane and to the horn antenna. Preferably, a bracket snugly secures the license plate to the one end of the vehicle, with the radar detector sandwiched therebetween and facing downardly. The bottom portion of the bracket has a horizontal lip spaced from the bottom edge of the license plate so as not to obstruct incoming radar signals that pass therebetween enroute to the reflector. The bottom portion also has a vertical lip with a window, thereby to substantially hide the reflector from view and at the same time to permit passage therethrough of radar signals to the reflector.
