Audio-Technica ATW-A49S
Single UHF Wide-Band Directional LPDA Antenna for IEM Systems


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.
