WA-0104S/WA-0108S Antenna Distribution Systems

Note: This model has been superseded. Please consider our suggested range of replacement models.

WA-0108S Antenna Distribution Unit

The WiNRADiO WA-0104S and WA-0108S Antenna Distribution Units combine low-noise amplifiers and power splitter devices 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 they are particularly suited for WiNRADiO multichannel receiver systems such as the MS-8118/WSB Multichannel Sonobuoy Telemetry System, these devices 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, 4 or 8 receiver outputs
 High IP3 amplifier
 High isolation between ports
 Rack mount 2U 19" enclosure
 Custom configurations available

The WA-0104/S system features 4 outputs while the WA-0108/S features 8 outputs. Internally, both products consist of a low-noise preamplifier with a high third-order intercept point, followed by a high-isolation power splitter.

The WA-0104/S and WA-0108/S systems are eminently suitable for government, military, telecommunications and other demanding high-end applications.


Rear Panel

WA-0108/S Rear Panel


The single antenna input and 4 or 8 outputs use N-type connectors located at the rear of the device. The fused mains power socket accommodates standard US and European voltages using a standard IEC computer power cord.
