Shure Professional Wireless Systems Helical Antenna (480-900 MHz)

The Shure HA‑8089 is a professional helical antenna designed to enhance radio frequency (RF) performance for wireless microphone systems and in‑ear monitor systems. Its helical design provides broad frequency coverage and high gain, improving signal reception and range in live sound, broadcast, and other RF‑intensive environments. The antenna operates passively and supports circular polarization to minimize signal dropouts and multipath interference.

Key Features and Specifications

• Wide frequency coverage: approximately 460–900 MHz suitable for UHF wireless communications.

• High gain (~14 dBi on‑axis) for extended range and improved signal strength.

• Circular polarization, distributing RF energy with minimal dropouts from movement or orientation changes.

• Directional beamwidth of about 57°, focusing coverage for improved performance.
