Scanner antenna with suction cup mount and coaxial cable. Uses a BNC connection to fit most standard scanners. Designed with mobile scanners in mind, especially in a car or pickup. The great thing about this antenna is it doesn't mount outside of your vehicle. Simply plug in the BNC connector the back of your scanner then, with the included suction cups, mount the wire to the inside of your windshield or rear window. Clean, easy setup to improve your scanners performance.
