Designed to provide enhanced signal transmission for UHF wireless in-ear monitoring (IEM) systems, Audio-technica's ATW-A49S is a wideband directional Log Periodic Dipole Array (LPDA) antenna that operates throughout a wide band range (440-900 MHz). It's a directional antenna that works great for extending the operating range and dependability of UHF wireless IEM systems used in large scale installations and stage applications. When used with an appropriate antenna combining system in a multi-system IEM application, it eliminates the necessity for multiple frequency-specific antennas.

The ATW-A49S offers support for virtually all UHF wireless IEM transmitters, providing a directional coverage pattern with a typical 90° beamwidth. It delivers approximately 6 dB of RF gain improvement over standard receiver whip antennas and is engineered to match standard 50 ohm impedance IEM transmitter outputs and receiver inputs.

It features high-quality low-loss BNC-type connectors that are physically positioned to minimize RF cable strain even when connected to large-diameter cables. Fashioned to mount to a standard 5/8"-27 microphone thread fitting, it includes an adjustable mount to enable horizontal and vertical adjustment for accurate positioning.

With its industrial-grade copper-clad epoxy fiberglass construction, it provides resistance to the effects of corrosion, UV degradation, and vibration, which allow for long life and stable performance under challenging operating conditions. The ATW-A49S comes fully assembled.

Consumer Alert

This particular wireless microphone device operates in portions of the 617-652 MHz or 663-698 MHz frequencies. Beginning in 2017, these frequencies are being transitioned by the Federal Communications Commission (FCC) to the 600 MHz service to meet increasing demand for wireless broadband services. Users of this device must cease operating on these frequencies no later than July 13, 2020. In addition, users of this device may be required to cease operations earlier than that date if their operations could cause harmful interference to a 600 MHz service licensee’s wireless operations on these frequencies. For more information, visit the FCC’s wireless microphone website at or call the FCC at 1- 888-CALL-FCC (TTY: 1-888-TELL-FCC).
