COFDM Repeater 1360 - 1750 MHz
This COFDM repeater unit was designed for military, broadcast and large UAV applications where long distance in the line of sight and non line of sight high quality video transmissions are required.
The repeater is equipped with four receiver units and one transmitter unit and can transmit the fourth received video streams to one transmitter channel.
All advanced parameters can be configured in advance through the remote control unit (with LCD display and 6 buttons) or by a PC.
