Sennheiser 509169 – Spectera DAD Antenna UHF

Product Overview

The Sennheiser 509169 Spectera DAD is a bidirectional digital antenna module for the UHF band (470–608 MHz and 630–698 MHz), connecting to the Spectera Base Station over a single RJ45 cable. This directional active transceiver antenna manages IEM signals, mic/line signals, and control data simultaneously over one PoE-powered link. As a Spectera UHF digital antenna with integrated RF components, it removes the need for separate combiners, splitters, and boosters in a wireless deployment. It is built for broadcast and large-venue installations that demand high channel density with simplified UHF RF infrastructure.

Product Description

The Spectera Digital Antenna Directional (DAD) is the remote antenna element of Sennheiser's Spectera bidirectional wideband wireless system. Operating in the UHF frequency range (470–608 MHz and 630–698 MHz), it transmits in-ear monitor signals to performers while simultaneously receiving microphone and line audio, all over a single digital link back to the base station.

Connectivity is handled through a ruggedized RJ45 connector carrying both data and PoE, supporting cable runs up to 100 meters on Cat 5e specification at 1000 Mbit/s. The antenna is powered over Ethernet at PoE Class 2, so a single cable provides both power and the full bidirectional signal path. Because RF components are integrated into the antenna itself, the DAD eliminates the dedicated RF gear — combiners, splitters, and boosters — that conventional wireless systems require, reducing rack clutter and installation complexity. The module carries an IP54 environmental rating and operates across an approximate temperature range of -10 degrees C to +60 degrees C, suiting both fixed and temporary installations. Signal security is handled with AES 256 CTR Mode encryption. The DAD provides continuous interference management and supports remote control from the Spectera ecosystem, giving integrators centralized oversight of every antenna in a deployment. The UHF variant is well suited to regions and venues where the 470–698 MHz spectrum remains the practical choice for wireless audio.

Technical Specifications

Frequently Asked Questions

What frequency range does the Spectera DAD UHF cover?

This DAD operates in the UHF band, spanning 470–608 MHz and 630–698 MHz.

How is the antenna connected and powered?

It uses a single ruggedized RJ45 connection that carries both data and PoE Class 2 power, supporting cable runs up to 100 meters on Cat 5e specification at 1000 Mbit/s.

Do I need separate RF combiners or splitters?

No. The DAD integrates its RF components, eliminating the need for dedicated combiners, splitters, or boosters in the wireless system.

Is the antenna suitable for outdoor or harsh environments?

The module carries an IP54 rating and operates from approximately -10 degrees C to +60 degrees C, making it appropriate for demanding fixed and temporary installations.

How is the wireless link secured?

The link uses AES 256 CTR Mode encryption to protect audio and control data.

What is the difference between the UHF and 1G4 DAD versions?

They are functionally identical antennas that operate in different spectrum: this model covers the UHF band (470–698 MHz), while the 1G4 version operates in the 1350–1525 MHz range.

What system does the DAD work with?

It is designed to operate with the Sennheiser Spectera Base Station as the remote antenna element of the Spectera wireless platform.
