WA-0831 Antenna Distribution System

>>> Prices and availability on request!


The WiNRADiO WA-0831 Antenna Distribution System is an antenna switching and distribution device. While it particularly excels in combination with the WiNRADiO MS-8118/G3 Multichannel Surveillance and Monitoring System, 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.

The WA-0831 system features 4 separate inputs for the HF/VHF/UHF ranges (a suitable mix of HF, VHF and UHF inputs is factory-customizable at the time of order) and 8 receiver outputs. Internally, the system consists of antenna matrix switches and high dynamic range preamplifiers. The WA-0831 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 and UHF modules for frequency ranges shown below:
 

Module	Bottom frequency	Top frequency
HF	0.4 MHz	30 MHz
VHF	30 MHz	300 MHz
UHF	300 MHz	1.8 GHz

 

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

The WA-0831 is factory-configurable for any combination of the four antenna inputs, which can be either HF, VHF or UHF. For example, a WA-0831 unit can have four HF inputs, or four VHF inputs, or one HF plus one VHF plus two UHF inputs, etc. All combinations are possible, as long as the total number of inputs is four. Here are a few common configuration examples:
