Abstract
The present power pack for a portable cellular telephone has a concealed radio transmitter for law enforcement use. The usual battery compartment in the housing of the power pack has a shortened battery compartment above which are located interior walls of the housing which are notched or recessed to support a printed circuit board carrying a radio transmitter. The housing has a shallow recess on the inside in which an antenna is potted. A space inside the housing receives a microphone for the radio transmitter. An opening near the lower end of the housing receives a push button switch for powering the transmitter from batteries in the shortened battery compartment.
