An S-Band LNB (low noise blocker) is a satellite communications component designed to receive signals from 1.55 to 5.2 GHz (gigahertz). Signals within this frequency range are commonly used for satellite radio subscriber services such as XM Satellite Radio and Sirius. The S-Band component connects to the receiver with a coaxial cable equipped with threaded connectors on the ends. Hooking up the components and tuning in satellite radio channels takes only a few minutes.

  1. 1

    Turn off the power to the receiver.

  2. 2

    Fasten one end of the coaxial cable to the threaded output on the S-Band LNB. If the jack is not labelled "OUT," look for an arrow on the component pointing toward the jack. Turn the connector on the cable end clockwise.

  3. 3

    Connect the other end of the cable to the "SAT IN" jack on the receiver's connection panel.

  4. 4

    Turn on the receiver and wait a moment for the component to initialise and recognise the S-band LNB connection.

  5. 5

    Turn the receiver's tuner control knob or use the remote control to access different satellite radio channels, which display on the LED panel on the front of the receiver.
