The AEW-DA660D is UHF active unity-gain antenna distribution systems that enable single pair of antennas to feed multiple wireless system receivers. Identical in all other respects, the AEW-DA660D operates over nominal 655 to 680MHz range. These units are designed to complement wireless systems operating in the D Band (655.5 to 680.375MHz) as well as other wireless systems operating in the same frequency ranges. Each antenna distribution system provides two identical 1-in, 4-out RF sections consisting of an antenna input, four band-passed isolated receiver outputs and band-passed cascade directional coupler to supply signal to additional equipment. All RF connections utilize standard BNC-type connectors.
