ATWDA49 Antenna Distribution System UHF Active 440-900 MHz

The ATW-DA49A is a 1U rack-mount active UHF antenna distribution system covering 470–990 MHz, enabling a single pair of remote antennas to feed up to four wireless receivers simultaneously while maintaining unity gain across the full wideband spectrum. Its high output third-order intercept point of 32 dBm provides exceptional intermodulation immunity, ensuring clean signal distribution even in high-density multi-channel environments.

Two diversity antenna inputs feed four RF outputs per channel, and a cascade output per channel allows multiple ATW-DA49A units to be linked for larger installations without signal degradation. Both antenna inputs supply 12 V DC at 250 mA to power active antennas such as the ATW-A410P or in-line boosters such as the ATW-B80 series, simplifying cable infrastructure by eliminating separate antenna power supplies. Fully compatible with the ATW-A49 LPDA paddle antennas for extended-range directional coverage.
