  • Quarter-Wave Ground Plane Design Delivers Omnidirectional Coverage Without Nulls Or Hotspots
  • 57 Selectable Channels Across Wideband And Narrowband Modes Accommodate Multi-Zone Deployments
  • Factory-Terminated 50-Foot RG58 Coaxial Cable Eliminates Field Connector Installation
  • Weather-Resistant Metal Construction Maintains Performance In Outdoor And High-Wind Locations
  • U-Bolt Bracket And Freestanding Base Provide Flexible Mounting For Poles Or Ground Placement

The Listen Technologies LA-107 is engineered for assistive listening installations where RF transmission must extend beyond interior walls or serve large open areas. With a quarter-wave design tuned to the 216 MHz band, this antenna supports both wideband and narrowband channel plans across 57 selectable frequencies. Its omnidirectional 360-degree beam pattern eliminates dead zones in auditoriums, outdoor amphiaters, worship centers, and multi-building campuses.

Built to withstand exposure, the metal construction and ground plane architecture maintain consistent impedance matching even in rain, wind, or temperature extremes. The U-bolt mounting bracket allows attachment to conduit, poles, or mast assemblies, while the self-supporting base permits freestanding placement when bracket use is impractical. Fifty feet of RG58 coaxial cable with factory-terminated BNC and PL-259 connectors ensures drop-in compatibility with Listen Technologies transmitters without field soldering or adapter hunting.
