The Listen LA-125 90° Helical Antenna Kit provides a flexible antenna mounting solution for Listen Technologies wireless listening systems. Designed to adapt the LA-326 Rack Mount Kit for antenna mounting, the LA-125 makes it easier to create a customized RF antenna installation for systems using LT-800 transmitters and LR-100 receivers.
The kit includes a 90-degree helical antenna, BNC cable, and BNC feed-through connector, providing the components needed to connect and position the antenna as part of a rack-mounted wireless audio system.
90-Degree Helical Antenna for Listen Wireless Systems
The LA-125 is designed for installations where antenna positioning and RF coverage are important. Its 90-degree configuration provides an alternative to conventional straight antenna mounting and can be useful when working within the physical constraints of a rack or equipment installation.
The antenna operates across the 72.0250–75.9500 MHz frequency range and supports the Listen system's available channels within this band.
Designed for Custom Antenna Installation
The LA-125 works with the Listen LA-326 Rack Mount Kit, allowing the rack mount system to accommodate antenna mounting. This provides installers with additional flexibility when determining how the antenna should be positioned within a wireless audio installation.
The included 18-inch BNC-to-BNC cable and BNC feed-through connector simplify the connection between the antenna and compatible Listen equipment.
Compatible Listen Equipment
The LA-125 is designed for use with Listen Technologies equipment including:
-
LT-800 FM transmitter
-
LR-100 FM receiver
-

It is particularly useful for professional installations that require a rack-mounted antenna configuration and controlled RF coverage.
RF Coverage
The LA-125 can provide a typical transmission range of up to 122 meters (400 feet) under suitable installation conditions. Actual RF range can vary depending on building construction, antenna placement, interference, operating environment, and other system conditions.
For small to medium-sized venues, proper antenna placement can help provide reliable coverage throughout the intended listening area.
