The Norsat Universal LNB Controller (ULC) sits inline on the IF cable and supplies everything a multi-band LNB needs: 13 V or 18 V band-select power at up to 500 mA, a 22 kHz tone, and an optional 10 MHz reference. That's ideal when your receiver or splitter can't provide them. Choose no reference, a built-in 10 MHz reference or a 10 MHz injection port, along with F-type, N-type or SMA connectors and switch, cable or line-length-compensation control.

Frequently asked questions
When do I need an LNB controller?
When the equipment on the IF cable, such as a splitter, distribution amplifier or test receiver, can't supply the voltage, tone or 10 MHz reference a multi-band or external-reference LNB needs.
What does line-length compensation do?
On long IF runs, voltage drop can stop the LNB from seeing the correct 13/18 V select level. The LLC option raises the output to compensate.
Need help with a multi-band receive setup?
Digisat engineers configure LNB power, band switching and 10 MHz reference distribution for teleports, monitoring stations and government terminals. Talk to an engineer.
