AUDIO-TECHNICA ATW-A49S Antenna

Audio-Technica ATW-A49S Broadband Directional Antenna

The Audio-Technica ATW-A49S is a passive directional UHF antenna (LPDA – Log Periodic Dipole Array) designed for wireless microphone and in-ear monitoring systems. It operates across a wide 440–900 MHz frequency range, making it suitable for most UHF devices. The antenna offers a 6 dB signal gain compared to standard omnidirectional antennas, significantly increasing operating distance and connection stability.

The antenna's construction is designed for intensive professional use: it is made of industrial-grade fiberglass with copper plating, resistant to corrosion, UV radiation, and vibration, making it suitable for both indoor and outdoor use. The BNC connector is mounted to reduce cable strain, and the adjustable bracket allows the antenna to be mounted on any standard microphone stand and precisely aimed at the stage.
