TELEVES 237003 is an Optical Converter QUATTRO MDU with TDT. It converts SAT (IF) and DAB/DTT signals from optical fiber (FC/PC) to QUATTRO polarizations and Terrestrial output, with F-female coaxial. It features Gain switch for the satellite band (three positions Low – Med – High gain), LED indicating the presence of RF signal, Compact design.
