SD1200 Wideband Amplifier model 1203

SD1203 Wideband Amplifier is designed with the use of modern elemental base. It provides high output level of 112 dBuV and allowed to minimize the dimensions. The device is produced in compact due-cast housing which provides optimal temperature regime. The amplifier is designed for compensation of TV signal losses in distribution networks. It is suitable for distribution networks of large block of flats or a group of houses. The devise has F-type connectors (3/8”). Input slope and level adjustments and interstage step slope adjustment allow setting the needed parameters of output signal.
