    Great work. I wasnt' aware of this end of the radio/TV hobby. It has been a long time since the days of giant C dishes. I thought all satellites were encrypted. Amazing that so much is still in the clear.

    While I"m not familiar with the specific equipment...Rather than adding additional LNA (amplifier) to the chain inside the shack, you should work to place the LNB as close to the satellite feed point i.e. outside on the antenna.

    This overcomes feedline losses and does not add noise like adding another LNA would.

    You may already have done this. bill

    Good point, thanks.
    The Octagon LNB has 60 db gain with a very low noise ratio (0.1 db)
    Experimenting with this COTS breakout board type LNA.
    It will add 20 db.
