Audio-Technica ATW-A49 UHF wideband LPDA (Log Periodic DipolevArray) antennas provide enhanced signal pickup for UHF wireless systems operating over 440–900 MHz, a remarkable 2-to-1 frequency 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-A49 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. The antennas are constructed of 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.
