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.The wideband directional antenna shall be designed to be used with
wireless in-ear monitor (IEM) transmitters. It shall conform to the
log periodic dipole array design providing enhanced signal pickup for
UHF wireless systems operating within a frequency range of 440-
900 MHz and shall offer an RF gain improvement of at least 6 dB over
standard transmitter whip antennas. The antenna shall be matched
to an impedance of 50 ohms and terminate in a standard BNC-type
connector oriented to provide minimal RF cable strain. The antenna shall
be designed for portable or permanent installation in indoor or outdoor
locations and shall include an integral mount, allowing for adjustment in the vertical and horizontal planes for accurate positioning. It shall
be constructed of heavy-duty copper-clad epoxy fiberglass with a low
reflective black finish. The antenna shall mount to standard 5/8"-27 threads and come completely assembled.
