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.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0603\/7982\/4364\/files\/Zz0wZDVhMmMyMmU3Y2YxMWYwYjk1OWNlM2Q3NWM0MGYwNw.png?v=1780788957\" alt=\"Sennheiser 509169 Spectera DAD UHF antenna rear RJ45 connection\"\u003e\u003cp\u003eConnectivity 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.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBidirectional Operation\u003c\/strong\u003e — The DAD simultaneously manages IEM signals, mic\/line signals, and control data over a single digital link.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUHF Frequency Range\u003c\/strong\u003e — It operates in the UHF band, covering 470–608 MHz and 630–698 MHz.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle-Cable PoE Connection\u003c\/strong\u003e — A ruggedized RJ45 connector carries data and PoE Class 2 power over runs up to 100 m on Cat 5e at 1000 Mbit\/s.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated RF Components\u003c\/strong\u003e — Built-in RF circuitry removes the need for separate combiners, splitters, or boosters in the wireless chain.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIP54 Rugged Build\u003c\/strong\u003e — The IP54-rated housing and rugged RJ45 connector suit both fixed installs and demanding temporary deployments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide Operating Temperature\u003c\/strong\u003e — The module operates across an approximate range of -10 degrees C to +60 degrees C.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAES 256 Encryption\u003c\/strong\u003e — AES 256 CTR Mode encryption secures the wireless link against interception.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterference Management and Remote Control\u003c\/strong\u003e — The DAD provides continuous interference management and remote control through the Spectera system.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTypical Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBroadcast studio\u003c\/li\u003e\n\u003cli\u003eAuditorium\u003c\/li\u003e\n\u003cli\u003eHouse of worship\u003c\/li\u003e\n\u003cli\u003eAll-hands room\u003c\/li\u003e\n\u003cli\u003eCommercial meeting space\u003c\/li\u003e\n\u003cli\u003eMulti-purpose room\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer Part Number (SKU)\u003c\/td\u003e\n\u003ctd\u003e509169\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eAntennas \u0026amp;
