The ATW-DA49 is a UHF (wide-band 440-900 MHz) active unity-gain diversity antenna distribution system that enables one pair of antennas to feed multiple wireless systems. Provides two “1-in, 4-out” RF channels; connects a pair of antennas to as many as four wireless receivers. Either passive or active antennas may be used. Both input jacks offer switchable +12V DC output on their center pins to operate Audio-Technica powered antennas or other in-line RF devices if desired. The unit features all-metal construction for extreme durability and protection from radio frequency interference.
