    This question relates to standard DOMESTIC wall mounted satellite dishes.

    Is the LNB off a 660mm oval dish (to be removed) compatable with a smaller 600mm dish or are the LNB's supplied specific to dish diameter?

    No-one seems to want to bite on this - I've never noticed dish size on any LNB advert so you should be OK. It's a very trivial difference in size anyway.

    No the dish size is only related to how much signal is grabbed from the air the bigger the more signal

    Bigger dishes are harder to line up

    You will find the dishes get a bit bigger the further north you go.

    But the LNB is the same on all of them.

    Folks that go to southern spain and portugal in their vans take a bigger dish as they are on thr fringe of the footprint for astra 2 and so need to grab as much signal as possible.

    Agree with previous posts, however, if the LNB you are removing is from a Maxview dish it won't physically fit the standard clamp on the domestic dish .. and visa versa.

    If it is a sky mini dish then the LNB often has a different fitting to the 'standard' LNBs which have a 40mm neck. Provided the LNB arm has a 40mm yoke then any 40mm LNB will be OK.

    I use a low noise LNB in one my 80cm dishes if I am not venturing further than the Alps or Pyrennees. I use the same LNB in my 1 metre dish if I go further afield. The difference in performance is not great but the bigger dish is much easier to stow and it is lightweight aluminium, the others are steel.
