The LBC-4000 is a 1RU indoor converter that translates between a 70 MHz IF (140 MHz optional) and L-band, using two front-panel accessible up or down converter modules and two redundant internal power supplies. It suits connecting legacy 70/140 MHz equipment to L-band block converters such as the MBT-4000. The LBC-4000-ST version carries a single module and adds front-panel sample ports.
