    Have to date rescued from scrap sky system( mesh dish and receiver), 105cmX97cm solid metal dish no boom, and now my gaze has landed on long disused larger dish measured it as being 130cm vertical diameter, can't measure horizontal as dish is wall mounted at 6ft of the ground.

    1, So my question is are there dishes which are unsuitable for multi LNB's?

    2. How do I distinguish between suitable and unsuitable?

    Also this dish seems in good condition and probably will cost me, what would be fair? I reckon Euros 60 max.

    Anything over 70cm can be used for multiLNB
    A missing arm is a problem as there is no easy way to calculate angle and length for an offset dish. For a centre fed dish, there is a a formula and of course since feed is on central axis you can easily re-adjust the distance of the tripod that holds up LNB.

    The bigger the dish the harder it is to align. You align the dish for LNB at the "proper focus" and then DO NOT move dish, but adjust each extra LNB in turn.
