Abstract
An active repeater assembly for in-vehicle use of personal communication devices is both simple and reliable. The assembly includes an RF amplifier coupled to first and second antennas, and is characterized by the total absence of removable coaxial connectors between the antennas and the amplifier. The outside antenna is an on-glass device, mounted on the opposite side of the same window. Oscillation is prevented by the provision of electromagnetic shielding between the inside and outside antennas.
