After setting up your wireless microphone, there are a few reasons why a wireless mic may drop out.
Loss of range: There is too much competition from local interference, from things like TV stations, motors, LED lighting, anything with a computer chip, or cell phone service in the 600 MHz bands. This can be mitigated using directional antennas, bandpass filters, and high-quality coax cables.
Multipath interference: This is caused by reflections of the transmitter's signal, like metal objects in the venue. The reflections can flip polarity and cancel out the receiver's antennas.
Our patented Diversity Fin antenna solves the distance problem by being co-located, while orthogonally mounted elements eliminate cross-polarization fades. Not only is it more convenient, it doesn't drop out!
