The LA-123 helical antenna provides extended RF propagation for assistive listening installations where standard integrated antennas fall short. Engineered specifically for 72 MHz band operation, it mounts directly to the BNC connector on Listen Technologies LT-800 transmitters and covers up to 400 feet in typical venues. The 90-degree element orientation allows flexible positioning without rack interference.
Integration teams choose this antenna for houses of worship, performing arts centers, and conference facilities where listeners are distributed across large rooms or multiple zones. Its dark grey finish and compact 8.25-inch profile suit front-of-rack placement when used with the LA-125 remote mount kit, enabling optimized signal path without visible infrastructure.
With 57-channel compatibility across wide and narrow band allocations, the LA-123 supports multi-system installations while maintaining regulatory compliance and interference-free operation in coordinated frequency plans.
