VSAT LNB Data Sheet (physical LNB)
The following table shows the data of the LNBs which are fitted in the ADU. The SAILOR 900 VSAT High
Power is designed to make any Ku Band frequency in the range of 10.7 GHz to 12.75 GHz available to a
VSAT modem by allowing the user to select the LNB LO of his choice – without having to exchange the
physical LNBs in the ADU. This is achieved by the sophisticated single-cable solution of the SAILOR 900
VSAT High Power.
See A.3.1 for configuration information.
