Thanks for the info and the pics, but I think I'll "pass" on slimline LNBs for the moment as I have worked out that I can do what I need by spreading normal 40mm LNBs across several dishes.
BTW: the SABS slimline one that I ordered came today, but turned out to be very old (from the state of the box) and totally dead (confirmed by my sat meter and substitution by a normal one)! The ebay seller says I have to pay the return postage, but I have told him that either he pays up or I open an ebay "case" because I have a cast iron case of a faulty DOA item
