Appendix: LNB and DiSEqC Settings

LNB

The LNB (Low Noise Block converter) is the microphone-link object in the center of the antenna dish. The values engraved on the LNB describe its local oscillator arrangement. LNB Settings must be entered for each satellite in the Satellite list.

Example: You purchase a new satellite antenna and recognize the microphone-like object in the middle of the dish as the LNB. Engraved on the side of the LNB are the words: Universal LNB L.O. 9.75 / 10.6 GHz (i.e. 9750 / 10600 MHz). Since L.O. (local oscillator) is 9.75 GHz, i.e. 9750 MHz, enter 9750 in the LOF1 textbox. Since L.O. (local oscillator) is 10.6 GHz, i.e. 10600 MHz, enter 10600 in the LOF2 textbox. Switch frequency is typically 11,700 for all LNBs, so enter 11700 at Switch.

A local oscillator (LO) in the antenna operates at its local oscillator frequency (LOF). A satellite dish antenna may have only one LO, or it it may have two LOs with a switch frequency marking the frequency at which the antenna switches from using the low band local oscillator to using the high band local oscillator. Values for LOF1, LOF2, and switch frequency depend on the specific model of dish antenna and how many LOs the antenna possesses.

DiSEqC

DiSEqC (Digital Satellite Equipment Control) settings are configured when the digital receiver card must receive satellite feed from multiple antennas or multiple LNBs. (Otherwise select None from the drop-down list.) The antenna DiSEqC settings must be specified for each satellite in the Satellite list. In the DiSEqc drop-down list, select the appropriate setting for the dish antenna:

None

Simple A
Simple B

The values should match designations on your antenna hardware; consult your equipment manufacturer.
