AUDIO-TECHNICA ATW-DA49 Signal Distributor

Audio-Technica ATW-DA49 UHF Antenna Distributor

The Audio-Technica ATW-DA49 is a broadband (440–900 MHz) active unity-gain antenna distribution system. It is designed for use with Audio-Technica 2000 and 3000 series wireless systems but is also perfectly suitable for other UHF systems operating within the specified frequency range. The device allows connection of a single pair of antennas and distributes their signal to four different wireless receivers (2 inputs x 4 outputs total).

The system is "active," meaning it compensates for signal loss that naturally occurs when splitting the signal to multiple receivers. Additionally, the device can provide +12V DC power via the antenna cable, allowing the use of active antennas or signal boosters. The robust metal casing ensures durability and protection against radio frequency interference, while the included accessories allow for immediate installation into a standard 19-inch rack.

Key Features

• Broadband Operation: Covers a wide 440–900 MHz range, suitable for most UHF systems.
• Unity-Gain: No signal loss between antenna input and receiver output.
• Antenna Powering: Switchable +12V DC power for active antennas (on the center conductor).
• Capacity: Serves up to 4 Diversity receivers (4 channels).
• Construction: Full metal casing, rack-mountable (1U).
