WA-0851 Antenna Distribution and Frequency Extension System

WA-0851

The WiNRADiO WA-0851 Antenna Distribution System is an antenna switching and distribution device integrated with inbuilt frequency downconverters. While it particularly excels in combination with the WiNRADiO MS-8118/G3 Multichannel Surveillance and Monitoring System (whose frequency range it extends up to 8.599 GHz), this device can also be used with third-party receiver systems. It can be operated stand-alone via front panel controls, or remotely via USB or LAN interface.

Features

 Wide frequency range from 0.4 MHz to 8.599 GHz
 Inbuilt downconverters to 0-1.8 GHz output frequency range
 8 antenna inputs, 8 receiver outputs
 Custom configurations available
 Manual or remote control
 High IP3 matrix switches and amplifiers
 High isolation
 High stability down-conversion
 Ruggedized enclosure for mobile operations

The WA-0851 system features 8 antenna inputs (4 separate inputs for HF/VHF/UHF ranges, 4 separate inputs for SHF) and 8 receiver outputs. Internally, it consists of antenna matrix switches, high dynamic range preamplifiers and high stability frequency downconverters. These downconverters convert input frequencies over 1.8 GHz (up to 8.599 GHz) to the 0-1.8 GHz output frequency range.

The WA-0851 system is eminently suitable for government, defence, law enforcement and other demanding high-end applications.

The antenna inputs can be customized and configured according to the user request by using HF, VHF, UHF, SHF1 and SHF2 modules for frequency ranges shown in the adjacent table.

The unit also contains convenient power supplies for external antenna preamplifiers (12 V current-limited DC voltage source is internally applied to the antenna leads of HF, VHF and UHF inputs).

 

Front Panel

WA-0851 Front Panel

The WA-0851 front panel contains 8 x 8 LED-illuminated matrix switch buttons, a remote enable button and the power switch.

 

Rear Panel

The eight antenna inputs use N-type connectors located at the rear of the device. The eight outputs are connected to the receivers using SMA connectors.

A connection to the USB port is via a standard USB-B connector and the LAN network interface is via an RJ45 connector.

 

WA-0851 Software

When used with the WiNRADiO MS-8118/G3 Multichannel Surveillance and Monitoring System, the WA-0851 software integrates seamlessly with the system, and the frequency range of the MS-8118/G3 unit automatically extends according to the WA-0851 configuration.

When used stand-alone, or in conjunction with third-party receiver systems, the WA-0851 unit can be controlled either manually using the operator control panel, or remotely via a supplied software application.

Programmers' SDK API is also available, to facilitate OEM integration and third-party application development.

 

How to Order

The WA-0851 is factory-configurable for any combination of the eight antenna inputs, which can be either HF, VHF, UHF, SHF1 or SHF2. For example, a WA-0851 unit can have eight HF inputs, or eight VHF inputs, or one HF plus one VHF plus two UHF inputs plus four SHF2 inputs, etc.

The order code is in the form of WA-0851/nT-nT-.. where n is the number of inputs of a particular input model type T. There are five possible types:
