摘要：
The invention relates to a wireless microphone system. One aim of the invention is to further develop such wireless microphone systems while another aim thereof is to improve the intermodulation distance between HF transmitters so as to allow a greater number of transmitters to be used in the same frequency band. Said aim is achieved by a wireless microphone system comprising antennas that are connected thereto, a circulator and/or an HF isolator being connected to the antennas or antenna.
