The ATW-A49S is a wideband directional log periodic dipole array (LPDA) antenna designed for enhanced signal transmission for UHF wireless in-ear monitoring (IEM) systems operating throughout a wide band range (440-900 MHz). This directional antenna is ideal for extending the operating range and reliability of UHF wireless IEM systems for largescale installations and stage applications. When used in a multi-system IEM application with appropriate antenna combining system, it eliminates the need for multiple frequency-specific antennas.Compatible with virtually all UHF wireless IEM transmitters, the ATW-A49S provides a directional coverage pattern with a typical beamwidth of 90 degrees. The antenna offers approximately 6 dB of RF gain improvement over standard receiver whip antennas and is designed to match standard 50 ohm impedance IEM transmitter outputs and receiver inputs.High-quality low-loss BNC-type connectors are positioned to minimize RF cable strain even when used with large-diameter cables. Designed to mount to a standard 5 /8"-27 microphone thread fitting, the antenna includes an adjustable mount to allow for horizontal and vertical adjustment for accurate positioning. Constructed of industrial-grade copper-clad epoxy fiberglass, the antenna is engineered to resist the effects of corrosion, UV degradation and vibration providing long life and stable performance under difficult operating conditions. The antenna is supplied and is completely assembled.
