Abstract: A wireless podium microphone (1) incorporates a body pack transmitter (26). The microphone (1) includes a microphone element (6) that is interconnected to a weighted base (2) by a deformable neck (3). The base (2) includes a first cavity (10) for housing electrical components associated with the operation of the microphone element (6) and a second cavity (21) in which the transmitter (25) may be securely mounted. A keyway (31) receives and constrains a button (30) that is affixed to the transmitter housing (27). Parallel guides (36, 37) are formed within the second cavity (21) and prevent lateral movement of the transmitter (26). An antenna guide (43) is mounted to the base (2) and permits the transmitter antenna (28) to be oriented to the desired antenna polarization.
