Product Introduction:

Model: LNB/RF SW 2*1
This device is used for primary/backup channel switching of L-Band RF signals. It provides dual RF signal level detection and dual optical level detection. When the primary channel has no RF signal, no optical signal, or its level falls below the preset switching threshold due to failure, the detection circuit automatically switches to the backup channel via MCU control. It will automatically switch back to the primary channel once the fault is resolved. The unit is equipped with an auto/manual switch for manual channel switching if required. Fault indicators are provided on the panel; LEDs automatically activate when signal levels drop below preset values.
