Sennheiser AWM UHF Wallmount Antenna for Evolution Wireless Digital Microphone Systems (UHF II: 823 to 1075 MHz) - 508866

Sennheiser AWM UHF Wallmount Antenna — UHF II (823 to 1075 MHz) for Evolution Wireless Digital

The Sennheiser AWM UHF Wallmount Antenna (UHF II: 823 to 1075 MHz) is an active directional antenna designed to maximize RF performance in Evolution Wireless Digital (EW-D and EW-DX) microphone deployments. By repositioning the antenna away from the receiver rack and closer to the performance area, the AWM UHF dramatically reduces multipath interference and signal dropouts — a critical advantage in large venues, houses of worship, theaters, and broadcast environments where cable runs between the antenna and receiver are unavoidable.

The AWM UHF features a fully integrated internal antenna concealed within a discreet flat-panel housing, making it visually unobtrusive when mounted on walls or ceilings in audience-facing spaces. Four selectable gain settings (-6, 0, +6, and +12 dB) allow system integrators to compensate for different cable lengths between the antenna and the receiver or antenna splitter. A multicolor LED on the unit provides instant visual confirmation of the selected gain level.

Power is supplied either through the BNC coaxial connection (phantom via the EW-D ASA antenna splitter or compatible receiver) or via a dedicated DC jack, offering flexible installation options. The unit mounts to vertical walls, horizontal ceilings, standard 3/8"-16 mic stands, or VESA 100 brackets, and includes a tilt adjustment for precise beam aiming.

Technical Specifications

Typical Applications

• Houses of Worship: Distribute antennas throughout large sanctuaries to maintain solid RF coverage for wireless microphone and in-ear monitor systems across the entire performance space.
• Theater & Performing Arts: Mount antennas at stage level or in wings to eliminate dropouts caused by body-blocking or distance from a rear-rack receiver installation.
• Live Event & Concert Production: Extend the usable range of EW-DX systems in large venues by positioning antennas closer to performers rather than relying on long whip antennas at the FOH position.
• Broadcast & Television Studios: Provides a clean, discreet antenna solution in on-set environments where exposed whip antennas are visually unacceptable.
• Corporate AV Installations: Permanent wall-mount installations in large boardrooms, auditoriums, and training centers using the EW-D digital wireless platform.

Frequently Asked Questions

Which Sennheiser receivers is the AWM UHF compatible with?

The AWM UHF is compatible with all stationary Evolution Wireless Digital (EW-D and EW-DX series) receivers and the EW-D ASA active antenna splitter. It is not intended for use with legacy EW (analog) series receivers.

What does the gain setting control?

The four gain settings (-6, 0, +6, +12 dB) compensate for signal loss over the coaxial cable run between the antenna and the receiver. Longer cable runs require higher gain settings to maintain optimal signal level at the receiver input.

How is the AWM UHF powered?

The antenna can be powered in two ways: through the BNC coaxial connection via phantom power from a compatible EW-D receiver or the EW-D ASA splitter, or via an external DC power supply connected to the dedicated DC jack.

What frequency band does this model cover?

This model (SKU 508866) operates in the UHF II band: 823 to 1075 MHz. If your EW-D system operates in the UHF I band (470 to 694 MHz), please see the AWM UHF UHF I model (SKU 508865).

Can I mount it on a mic stand?

Yes. The AWM UHF includes a 3/8"-16 thread mount for standard microphone stands, in addition to wall, ceiling, and VESA 100 mounting options.

Where can I purchase the Sennheiser AWM UHF Wallmount Antenna?

The AWM UHF (UHF II, SKU 508866) is available from Creation Networks, an authorized Sennheiser dealer for professional wireless audio systems.
