A.1 VSAT LNB Data Sheet (physical LNB)
The following table shows the data of the LNBs which are fitted in the ADU.
The FV-110 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 FV-110.
Please see A.1.1 for configuration information.
