iDirect LNB 11300 to 10000 Option File

Your satellite downlink frequency may be calculated as follows:
    1,346,149,999  Hz (L band cable frequency)
+  11,300,000,000 Hz (LNB local oscillator frequency)
=  12,646,149,999 Hz
or 12.646149999 GHz

This 12.6 GHz frequency is in the upper part of the Ku band and you need an LNB with a local oscillator like 11.3 GHz to get the cable L band frequency down to within the design range of the iDirect modem receive input, which is, I believe, 950 - 1700 MHz.

If you consider the 10 GHz LO LNB.  The calculation would give an output frequency into the cable of 2.646 GHz and this is not acceptable to the iDirect modem.  The 10 GHz LNB will have been made for satellite downlink frequences like 10.95 - 11.7 or 10.95 - 12.15 GHz, so you are unlikely to see much LNB output at 2.646 GHz anyway.

Explain the situation to your service provider.  There is a possibility that they may have another iDirect hub service on a different satellite at a suitable frequency for your 10 GHz LNB.  Otherwise you will need to buy a Ku band LNB with 11.3 GHz local oscillator frequency.
