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.

| 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:
