Shure Brothers Inc UA8-578-638 Omnidirectional Antenna

Product Description

The SHURE BROTHERS INC UA8-578-638 is a half-wave omnidirectional antenna designed for use in professional wireless audio and RF distribution systems. This antenna radiates and receives signal equally in all horizontal directions, making it well suited for applications where transmitter position varies or multiple sources must be covered from a single receive point. The UA8-578-638 covers the 578 to 638 MHz frequency range. It is typically installed by licensed audio-visual system integrators, RF coordinators, and experienced AV technicians working in fixed-installation or touring-production environments.

This antenna is appropriate for use in venue installations, broadcast environments, houses of worship, conference rooms, and live-event production settings where a reliable RF front end is required. The half-wave design provides a predictable, low-angle radiation pattern that supports consistent signal pickup across a wide coverage area. It ships as a single unit and is intended for use with compatible wireless receiver systems operating in the covered UHF band.

Key Features

• Half-wave omnidirectional radiation pattern for broad horizontal coverage
• Frequency range spanning 578 to 638 MHz UHF band
• Single-unit packaging for straightforward inventory and deployment
• Suited for both permanent installation and portable production rigs

Compatibility

Designed as an OEM-style antenna for UHF wireless receiver systems operating within the 578 to 638 MHz frequency range. Verify receiver input impedance and connector type before installation.

Installation Notes

Installation should be performed by a qualified AV systems technician or RF professional familiar with UHF antenna placement and cable-loss management. Power down all associated receiver equipment before connecting or disconnecting the antenna. Follow applicable local and federal RF regulations, including FCC Part 74 rules where relevant for licensed wireless microphone operation. Avoid routing antenna cables near high-voltage AC wiring to minimize interference.
