WA-0108/U Antenna Distribution Unit - Preliminary Information

WA-0108/U Antenna Distribution Unit - Front Panel

The WiNRADiO WA-0108/U antenna distribution unit supersedes the earlier WA-0104/0108S models. It combines a low-noise amplifier and power splitter device in an optimum combination, particularly suited for VHF and UHF applications where a single antenna needs to be connected to up to 8 receivers. While this model is particularly suited for WiNRADiO multichannel receiver systems such as the MS-8118/WSB Multichannel Sonobuoy Telemetry System, it can be also used with any third-party receivers and antennas.


 Wide frequency range from 50 MHz to 1.6 GHz
 Inbuilt low-noise preamplifier
 One antenna input, 8 receiver outputs
 High IP3 amplifier
 High isolation between ports
 Rack mount 1RU 19" enclosure
 Custom configurations available

Internally, the product consists of a low-noise preamplifier with a high third-order intercept point, followed by a high-isolation power splitter.

The WA-0108/U antenna distribution units are eminently suitable for government, military, telecommunications and other demanding high-end applications.
