The Audio Technica ATW-A49a is a pair of UHF wide-band directional LPDA (log periodic dipole array) antennas providing and enhanced signal pickup for UHF wireless microphone systems throughout a wide band range (440-900 MHz).

Each antenna paddle is matched to 50 ohms impedance with an integral high-quality low-loss BNC connector; 6 dB gain. For permanent or temporary installation; mounts to 5/8"-27 threads.

The Audio-Technica ATW-A49a UHF wideband LPDA (Log Periodic Dipole Array) antennas provide enhanced signal pickup for UHF wireless  range. This bandwidth includes all UHF TV channels (14–69, 470–806 MHz).

Supplied in pairs, these directional antennas are ideal for extending the operating range and reliability of diversity UHF wireless systems. They also eliminate the need for multiple frequency-specific antennas.

The ATW-A49a is designed for applications requiring increased distance between the transmitter and the receiver—as in stadiums, concert tour venues, theater and large performance areas, or any area where  line-of-sight may be obstructed. This ruggedly constructed paddle-style  antenna is equally suited for installed and portable applications.
The antennas are compatible with virtually all UHF wireless receivers and provide a directional coverage pattern with a typical beamwidth  of 90 degrees. They offer approximately 6 dB of RF gain improvement over standard receiver whip antennas. Antenna impedance is 50 ohms. 

Constructed from industrial-grade copper-clad epoxy fiberglass. This heavy-duty, durable construction is engineered to resist the effects of corrosion, UV degradation and vibration, providing long life and stable performance under difficult operating conditions. High-quality, low-loss BNC connectors are positioned to minimize RF cable strain.

The antennas are supplied completely assembled.
