Antenna conector 90 * BNC

Is there a good place to look for a BNC adapter that is 90* and one end connects to antenna conector and the other is BNC to go to scanner, I dont want the wire to go straight out the back of the scanner, I dont have a lot of room where the scanner sits. I need the wire to come in from one side at a 90* turn?



Thanks
