Overview
The Sennheiser A 1031-U is a passive omnidirectional antenna for wireless mic and in ear systems working between 450 and 960 MHz. It is used for both transmitting and receiving, so it suits receivers, antenna splitters and IEM transmitters alike.
Mounted up and in clear line of sight, it usually improves range and dropouts over rear panel rod antennas.
Works with Sennheiser evolution wireless G3 and G4 receivers and SR IEM transmitters, the ASA 1 splitter and the AC 41 combiner.
