The Shure HA-8091 is a domed helical antenna designed to provide reliable wireless signal transmission or reception with improved bandwidth and range for system integrators and audio engineers in large-scale live stage applications. 360° polarization reduces dropouts and yields dependable RF energy for receivers and transmitters, whether stationary or mobile. It operates in the 460 to 900 MHz frequency range and offers 14 dB of rear rejection. With 9 to 11 dBi of gain, signal strength is not compromised. A right-angle BNC female connector ensures standard connectivity.
