The all-new STI-CO TRAX GPS Antenna is a sleek black antenna smaller than a credit card - just 1/8-inch thick - yet rugged enough to hide under the bumper of a car.The TRAX GPS Antenna can be placed either horizontally or vertically in tight places. Mounting is easy, using either adhesive or a heavy-duty magnet. It provides a new option for vehicle or asset tracking that will not be detected; once in place, it becomes virtually invisible. The STI-CO TRAX GPS Antenna works with most tracking systems using a 3.3 volt device. Users may choose from a wide variety of connectors.
