External Antenna
The Mobile Crossing external antenna is our Really Nice premium external antenna.  We don't think you'll need the external antenna for our Bluetooth unit, and for that reason it is optional equipment and nice to have.  Our external antenna features a non-marring magnet that lets you stick and remove the magnet without damaging the finish on your car.  It is waterproof and designed to hold up well.  We've had these built using an Extra Long length of the high quality cabling so you may install anywhere.  Another nice touch is the MMCX style gripping connector that provides a firm lock that won't slip out.
