The Focal length (F) of your dish is 97.44cm giving you an F/D ratio of 0.32
A C120 lnb of your choice (Inverto, Invacom, MTI etc.) coupled to an Invacom ADF-120 adjustable feedhorn set to 6mm protrusion should work (this setting will give you the correct illumination). You might have to fabricate some sort of LNB holder if the ADF-120 neck diameter is not the same as your Fugi. Then it's just a matter of fine alignment. I use mirrors on my dish (pointed at the sun) to find a vague focal point, then ensure this point is just inside the neck of my feedhorn. I also use a laser pen with a home made insert in the feedhorn mouth to ensure the lnb is pointing at the centre of the dish.

Thank you for your quick response. now with this dish i am getting Insat 2E3B C band channels. I am trying to convert this dish for KU band (meatsat3). Fugi SG-900 having an integrated scalar ring. I purchased it yesterday. No clue how to use it.

Sorry, I misunderstood, I thought the Fuji was C Band.
