    ...or do I need to source an LNB to suit my specific dish?

    (its an oval minidish..not sure if it has a make/model number as i havent checked yet)

    edit: unviversal is swahili for "universal" :)

    There are 3 basic types of lnb fitment

    1 Sky minidish fitting with a spigot that pushes into the end of the lnb arm
    2 Standard 40mm collar fittings for virtually all offset arm dishes
    3 C120 lnbs for prime focus lnbs.

    Although standard 40mm collar lnbs can be fitted to Sky minidishes unless it is a free one lying around, it is better to purchase the correct type for fitment to the Sky minidish. This is down to the design of the front bit of the lnb (nearest the dish) which has an internal waveguide to focus and align the satellite signal - those for Sky minidishes have an oval throat and those for standard dishes are circular - this design is to optimise the signal reflected back from the dish.
