WiNRADiO WA-0851 Antenna Distribution System

WA-0851 Antenna Distribution System

The WiNRADiO WA-0851 Antenna Distribution System is an antenna switching and distribution device integrated with inbuilt frequency downcoverters. While it particularly excells 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 be also 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
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, preamplifiers with an extremely high third order intercept point and high stability frequency downconverters.

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

Module	Bottom frequency	Top frequency
HF	0.4 MHz	30 MHz
VHF	30 MHz	300 MHz
UHF	300 MHz	1.800 GHz
SHF1	1.800 GHz	3.500 GHz
SHF2	1.800 GHz	8.599 GHz

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

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.
