Motorola Saber
The Motorola Saber portable radio is a product series of Motorola USA, Inc. The Saber is a commercial radio that was developed for the U.S. military sometime around 1989. The Saber is widely recognizable by thin, sleek design compared to other radios at the time. Despite the fact that the Saber was originally marketed to the military, many law enforcement agencies and fire departments realized the benefits of the Saber and Motorola soon had a much larger customer base for the radio than they expected.
