Abstract: A superheterodyne radar detector includes a compact watertight and durable housing to which a variety of clips and fastening means may be attached. Batteries are provided for powering the radar sensing circuitry, as well as means for recharging and/or replacing batteries. Two antenna horns are mounted within the housing directed perpendicularly with respect to one another and a shield is provided for mounting over one of the two antenna horns. A sensed radar signal is indicated by an earphone and/or an indicator light and/or a speaker.
