This antenna comes with a BNC connection but there are probably adapters to convert the BNC to Motorola. No ideas on antennas with suction cups. Radio Shack used to make a 6 ft connector with suction cups on one end with a BNC female connector and a BNC male connector on the other end. That was designed to put on the inside of a car window or a house window. I will post a picture of that in a few minutes.
