Brief description

To cover large distances, transceiver systems with an output power of 500 W and 1000 W are available. These solutions provide exceptionally high radio link availability even under moderate propagation conditions. 
They provide the higher signal-to-noise ratios required when transmitting at the high data rates needed for worldwide embassy radio systems, civil ATC systems or military applications. Of course the systems also offer frequency hopping capabilities.
